    Hi guys, I bought my 1999 Porsche 911 C4 Tiptronic back in January and I've been doing little projects on it ever since. I used to have a 2016 Dodge Challenger R/T Scat Pack with a 6.4 liter V8 that I traded in last summer, but I was missing the sports car feeling too much so decided to buy the Porsche. One of the things that stood out to me on the test drive was just how sluggish and unresponsive the Tiptronic gearbox felt compared to the one I had in the Dodge. Since the rest of the car was in very good condition (invoices for every oil change & repair going back to 2003, IMS bearing changed, etc.) I decided to buy it anyway, assuming I would get used to having to mash my foot into the carpet everytime I wanted the thing to move. Looking through this forum and others, I heard about the Sprint Booster and how it might help with this problem. For those of you that don't know what this is, it is a small plug that sits between the gas pedal and the cable harness running to the ECU and that changes the signal sent to the car from the position of the gas pedal. The factory set up makes it so that when you push the gas pedal, the revs rise very slowly for the first 50% of pedal travel. I think I read somewhere that halfway down, the pedal will only give you about 25% of the power. This means that in order to get the Tiptronic box to do a downward shift, you really REALLY have to mash the pedal and do it in a quick manner. In general it makes the whole car feel unresponsive and not at all like the free-revving, happy sports car I thought I was getting. The Sprint Booster module (which only works on cars with electronic throttle control or "e-gas" pedal) will take the gas pedal input and modulate it to reflect a more aggressive pedal action. The only thing that changes really is the voltage that is sent to the car's ECU, and how this is calculated in relationship to the position of the gas pedal. The unit comes with a little control gadget where you can set it to one of three basic settings - Factory (simple pass-through, nothing changes from stock), Sport (about a 30% more aggressive response), and Race (about 50% more aggressive). Within both Sport and Race you can then fine tune with an additional setting from 1-9 for each of the two categories. By default the device will put you in "5" or the middle ground. The device costs you about $300 and there is no discount to be had from any of your typical market places. I simply bought mine directly at the manufacturer's website. Since it was my birthday last week, I decided to treat myself and see if it might work. You have a 30-day money back guarantee and the install process is completely reversible, so I figured I'd give it a go. If it actually helps make my tiptronic feel peppy it will have been worth every penny. If not, I'll just return it. For the installation my first problem was figuring out if my particular car had an e-gas or electronic throttle system or not. Looking at the gas pedal I can see a cable running up the bulkhead so I wasn't feeling too optimistic. With the help of others on this forum, I learned that all 996's have e-gas except the 98-99 C2. I also popped the hood and looked at the throttle body itself. To be extra sure, I also asked the vendor to confirm that my particular model would work with the product. The manufacturer's website only shows MY 2000 and beyond as approved for installation, but they came back and confirmed that in fact the -99 C4 does have e-gas and so I could proceed with the purchase. 3-4 days later I get the box in the mail. It is a tiny little thing and doesn't appear to be much for the $300 I paid for it, but whatever. The installation manual shows pictures of the device being plugged into a port located somewhere on the gas pedal assembly itself. It is clearly the most common spot for most manufacturers to link the throttle to the ECU, but that's not the case in a Porsche 996. The gas pedal pulls on a cable and if you follow the cable up from the pedal, you'll see it attaching to a metal box conveniently located under the actual dashboard, and at an impossible angle for any human being to get to. In these cases I like to resort to child labor, so I bribed my 13-year old son to help me. By laying upside down in the driver's seat and sticking his head + one arm under the dashboard, he was able to get the device plugged in correctly in as little as 2 hours. I was basically reduced to cheer leader, and voice of reason to guide his efforts. We made use of my cell phone camera to try and figure out from the pictures how to disconnect the old plug and get the new Sprint Booster in place. The pictures attached to this post will show you how we figured it out: The entire installation process is done by touch and feel as you cannot see any of the components directly. I would recommend our approach of using a camera, talking about what we need to do next, and then use your fingers & imagination to figure out what it is that you are doing. We found it helpful to start with where the cable attaches to the box, then run your fingers over until you hit the little metal flange that sticks out with the white plastic butt underneath it. When you have your hand there you know that the plug itself is just above it. After the initial installation we immediately took the vehicle out for a ride. The gas pedal felt weird, and we had intermittent revving and a noticeable delay when pressing the pedal. I figured it was simply down to the device having to calibrate itself so we went for a ride. 20 minutes in we get a check engine light come on so we headed back to the garage. Ever the optimist, I simply disconnected the battery to reset the CEL and then went out for another drive. This second time it worked beautifully! The car felt like a different animal all together, and the gas response was crisp and immediate. Problem solved, or so I thought, and we called it a day. The second day I went for a drive and got not only a CEL but also the PSM and ABS warning lights. At this time I was ready to call it a day and send the device back since I don't want to have to deal with buggy electronics or stuff that I can't trust. Called up the son again to have him pull everything out and that's when he noticed that the OEM male connector at the end came lose by simply touching it. Turns out we hadn't been able to plug it in all the way until it latched onto the Sprint Booster module. I guess it is not manufactured to the same tight spec as the OEM stuff, and by a fraction of a millimeter the plug can't go in far enough to secure it with the latches. Using force and patience, we eventually managed to push it all the way in until we heard the very satisfying "click" of the plug latching onto the module. If I have to take it off again because it comes loose, I will certainly use a file to remove a bit of material on each latch and ensure that they lock into place without having to push too hard. Since this point I have driven the car 4-5 times and about 50 miles, driving it as I usually do and without holding back in any way. No CEL or other warning lights and the thing runs really well. Having tried the different settings, I have decided to leave it in Sport-5 which I think is a happy medium for a sporty feel without compromising the ability to drive smoothly when you want to. Race mode makes it more binary, and it is like mashing the pedal at every stop light. It might be fun on a track, but for everyday driving it is just too aggressive. In Sport-5 it'll pull away softly in 2nd gear like it did with the factory settings, but if you simply give the pedal a little shove it'll immediately downshift to 1st gear and take off with gusto. All in all I have to say that this was very much worth it. The car feels different - more sporty and responsive, just like you'd want a Porsche to feel like. I know this doesn't add any power to the engine but just by having the Tiptronic gearbox work more like a modern sports car it really changes everything. I'm now planning on driving it for the full 30-day money back period, and if I run into any issue I will post an update to this forum. Cheers, Magnus

    111,000 miles so far. I’ve put 6,000 on so far this year. Discovered the AOS needs to be replaced day before yesterday. Looking forward to the tinkering opportunity!

    Most quality shops did, just as the followed their “preinstallation inspection “ directives, both of which benefited the car’s owner at no cost to the shops. We regularly had customers ask us about both when shopping for someone to do the retrofit, signs of an informed consumer. DIY’s on the other hand were another story.......

    I believe that you will find that list is for the IMS Solution only, there is a sperate list for their ceramic hybrid retrofits.

    Pelican is infamous for publishing questionable maintenance procedures, just look at their IMS procedures, which resulted in more screwed up engines than you can imagine. I did this for a living; drop the engine down a couple of inches and you will be done with the AOS in one hour. Pull the intake off and you will have hours of reinstalling, followed by hours more of smoke testing to find the vacuum leaks. View simply is not worth the climb.

    You would be better served to run a voltage drop across each of the primary cables, none of them should drop more than 0.5V across their length after the connections are clean. Any greater voltage drop is a sign of corrosion inside the cable creating resistance and the voltage drop, which can only be corrected by replacing the cables.

    Check the high current connections, they are to thick ones from the battery under the seat to the starting circuit and to ground. Now that you know it's a corrosion problem then unbolt and clean them, don't just look. Check any connectors you can get access to as well.

    Interesting, that product is a direct rip off of the LN IMS Solution, which is patented to Jake Raby. Stand by for this to be shut down in a lawsuit...…..

    Hate to say it but that yellow sludge in the oil filler tube and cap is a classic sign of not running the engine long enough and hot enough to burn that stuff off. If you had the coolant system pressurized and leak tested, what makes you think you have a coolant leak? Surely something would have happened if the leak test failed. And one quart low on oil? When was the last oil change and how many miles on the oil change? It is not unusual to have to add a quart of oil every once in a while depending on mileage. As said, if you are smelling coolant in the cabin (but again, you had a pressure test done on the coolant system so ????) it could be your heater core. Are you losing any coolant?

    They are welded, need to grind it off from below, drill 8mm hole, fit the replacement by welding it underneath to the body. Stud should be M6, normally that would be 10mm socket for the nut. Tightening torque is 6.5ftlb.

    2003 Cayenne S So my wife's pepper had a fishbowl in the passenger rear taillight for awhile now. I guess long enough that it shorted something out as the running lights no longer have power. I have 12V going to every pin in the connector except the common orange wire for the dual bulbs in the bottom of the tail light. Brake lights, turn signal, back up light work just fine. The fuse on the passenger side panel is in proper working order. I believe there is a controller box for the taillight somewhere in the rear cargo area (not the tow controller, the actual taillight controller). I am guessing that the driver for that power line has shorted out since I cannot get 12V on that one single pin (I think it is pin 3; grey/red strip wire). I have the rear cargo area torn apart looking for the control box with no luck finding it. The cable harness branches and comes back together in so many places I cannot identify where that Grey/red stripe wire gets power from. Does anyone have knowledge, or a graphic of where that control box is? The wife is getting pissed that she can't drive the truck at night for fear of getting pulled over by the police. Any help is greatly appreciated!!! -JB

    These rubber "accordians" can crack over time. Fortunately the rubber piece is only around $60, and can be replaced easily. You'll need to set aside about an hour and a half if you haven't done this before. Tools needed: Flat-bladed screwdriver 4mm allen wrench Ratchet with short extension and 10mm socket Parts needed: The bellows Two plastic expanding fasteners (might come with the bellows) First, deploy your spoiler manually, and shut off the ingnition. No need to disconnect the battery. You will see, along the rear edge, four caps, as seen below. These pry out easily with your fingers or with a flat bladed screwdriver. No paint to worry about, just try not to mar the plastic. With the caps off you can access the 4mm allen head bolts: I found these to be a bit tight due to exposure to the elements, but I was able to get them off with an allen key. A long allen socket would work better. Once the bolts are out, the top tray (painted part) of the spoiler can be slid toward the rear and off. Put it somewhere where it won't be scratched. Now you can see the fasteners holding the top of the bellows to the spoiler. There are two explanding plastic fasteners, one on each corner, and several sliding hooks. I destroyed my plastic fasteners since my new bellows came with new ones. Just nipped them off with wire cutters. With the two plastic fasteners off you can disengage the hooks and detach the top of the bellows by sliding it to the right, and down. The top edge of the bellows is actually sandwiched between a long metal strip and the spoiler. The metal strip has the hooks that go through pre-cut holes in the bellows. View from below: With top of bellows detached: With the top of the bellows detached, open the engine lid. You will see several circular clips holding the bottom of the bellows to the engine lid: There is one under the fan, so you will have to detach the fan. Just three 10mm bolts. Just let it hang by the cable, out of your way. Be careful not to scratch your paint while removing the clips. In my case, the clips themselves had scratched the paint a bit. Fortunately this is one of the body areas that receives only a "rough" paint job from the factory anyway. Save those clips. It is not necessary to replace them. With the clips removed, you can pull the bellows out. As with the top, there is another frame piece running the length of the bottom of the bellows. This sandwiches the bottom of the bellows to the engine lid. The bellows has pre-cut holes for the nubs on the metal strip: Lay your old bellows alongside you new one, so that you can see how the top and bottom frame strips fit. Reassembly: Transfer your frame pieces to your new bellows. Then attach bottom of bellows to engine lid with the circular clips. Push those numbs through and get those clips up as tight as possible. The idea is to clamp onto the lower bellows edge. Re-attach the fan. Close engine lid Make sure the top frame piece hooks are threaded through the top of the bellows, push up through the corresponding holes in the spoiler, and slide to the left to secure. Make sure all of the hooks are engaged and snug. Then insert and secure the two plastic expanding fasteners in the corners. This step will confirm that you have the bellows and the spoiler snug and aligned properly. Now grab your painted spoiler top, and look under it to make sure the locking tabs are lined up. Push down, and slide toward the front of the car to lock the tabs. The top and bottom of the spoiler should mate very well. If you feel gaps around any edges, check and adjust. Finally, secure the top of the spoiler with the four allen screws. Put the plastic caps on, and manually raise and lower the spoiler to make sure you haven't left any tools in there...

    2003 Boxster - Purchased new in December '02 with mileage from the Port to my dealer here in So Cal (17 miles). I just changed my oil at 135,000 miles yesterday. I've only performed standard maintenance and do most of it myself: Oil and Filter (Amsoil 5W-40/Mahle Filter) every 15K Front Brakes - 60K Drive Belt - 60K Front and Rear Brakes - 120K Drive Belt - 120K Clutch as not been replaced on the vehicle. I have had to have my key reprogrammed on a couple of occasions over the years. I also had to purchase the shroud that must be removed to fill the transaxle twice due to road debris. I drive the car daily here in Southern California and drive a windy mountain road called the Ortega Highway to get from Southern California Wine Country to Orange County. I seem to replace the rear tires every 25K to 35K (I dumped the Pilots on my first tire change for a better wearing tire). Fronts about every two sets of rear tires. Best car I've every owned. It's my daily driver and runs incredible. Other than rock chips on the front from Southern California freeways, you would think the car had 20K miles on it. I just got in from the store...top is down and it's a beautiful day here today. Must be back in the 80's...heading back out to grab some carne asada for the barbecue.

    9) Remove the xenon ballast in the bi-xenon headlights (6 bolts) then disconect the harness, now remove the 5 pins (thin black, thin brown, red, yellow and uncovered ground wire) you only need two wires to turn on the xenon (Strong black and Strong brown) 10) Cut all the wires in the connector (bi-xenon headlight) NEAR to the connector and then use the plastic trick to remove it from the headlight. Take the Halogen connector and use this diagram: PIN 1 - Parking Light Lead (+) PIN 2 - High Beam Adjuster Supply PIN 3 - High Beam Adjuster Sensor PIN 4 - High Beam Adjuster Ground PIN 5 - EMPTY PIN 6 - Low Beam Lead (+) PIN 7 - High Beam Lead (+) PIN 8 - Additional High Beam Ground (-) PIN 9 - Turn Signal Lead (+) PIN 10 - Low Beam Ground/Parking light/Turn Signal (-) PIN 11 - EMPTY PIN 12 - EMPTY (tanks to toby http://www.renntech.org/forums/index.php?s...pic=1189&st=20) 11) Tap every wire as this diagram says, note that inside the headlights (Halogen / bi-xenon) the grounds wires are brown and leads black 12) if you want to, remove this resistor from the bi-xenon shuttle 13) Remember to tap the bi-xenon shuttle + Auxiliary high beam whit the pins PIN 7 - High Beam Lead (+) PIN 8 - Additional High Beam Ground (-) Corner light + xenon ballast whit PIN 6 - Low Beam Lead (+) PIN 10 - Low Beam Ground/Parking light/Turn Signal (-) 14) Check all the wires, solde and insulate all wires. 15 reinstall the xenon ballast, connectors and you are done!

    Ok here we go: vehicle: Porsche Cayenne S 2004 (Halogen Headlights - No Air Suspenssions - No Headlights washers) Factory halogens headlight part no. bi-xenon headlight part no. Before start i have to remove the orange look of the headlight... Done! Things you need to know... you DON`T need the bixenon wire harness (part no. 955 631 239 10) to make the bixenon headlights work. I re-wire the internal of the bi-xenon headlight. * The only diference are: 1) bi-xenon have an extra light called (cornering) i tap this to the xenon wires, every time the xenons turn on both cornerin lights goes on. ALSO this prevent the computer detect a problem whit the low bean xenon ballast. 2) I tap the bi-xenon shuttle whit the auxiliary high beam lights, if i don`t have the xenons on and i flash the high beams, only the auxiliary and the shuttle goes on, NOT the xenon. there is a resistor in the shuttle that you can remove (more details next...) * Start 1) Take out both headlights (Please see manual for more info) 2) Take the 3 covers out 3) Remove the Autoleveling motor (remove the 3 pin harness and two bolts) from the Halogen headlight 4) You have to take out the Pin conector, to do this insert a plastic (Use an old Credit card, cut it in two and then resize it to 3cm wide) insert the plastic at the top and bottom inside the housing make sure it reach the end and then pull out the connector (This is a pain in the a..) 5) Once the connector is out start to cut each terminar as long as you can, NOTE: don`t cut the 3 pin connector in this harness you will use this whit the autoleveling motor in the bi-xenon headlight. in the end you will have this: 6) Say bye bye to the halogen headlight... don`t be panic now... 7) Remove the 3 covers in the bi-xenon headlights 8) Now remove the Autoleving motor (remove the 5 pin harness and two bolts), then install the 3 pin Autoleveling motor Side by side (Left Halogen 3 pin, Right bi-xenon 5 pin)
