  1. Thanks Loren. Does anyone have the DME OBD II service manual for 5.2.2 996? If so can you scan in the pinouts or pm me? Thanks, D.
  2. Looking for the connectors and DME pinouts for the Motronic 5.2, 7.2 and 7.8. Thanks, D.
  3. What are the rates for the 996 Fuel injectors and fuel pump for all models? Are the before catalytic O2 sensors wideband on N/A as well as FI cars? Thanks, D.
  4. Here is some more information discovered. 3.6 has a longer stroke and the same bore as the 3.4. 3.4 Non-Egas uses Motronic 5.2 Non Egas models include those without PSM from MY98-00. 3.4 Egas uses Motronic 7.2 (All C4s and PSM cars) (7.2 cars also have 300hp vs 296hp which is a skeptical issue because this would mean the MY99 C4s have more power than the MY99 C2s) 3.6 uses Motronic 7.8 (same version for turbo) (Motronic 7.8 is more efficient than the *.2 versions mentioned above meaning the larger displacement is better on the environment and still makes bigger hp.) It looks like the egress valves might be larger on the MY02-05 3.6 but I cannot find supporting information at this time. The 40th anniversary car has major headwork, oil baffling, a different intake, headers and a remapped Motronic 7.8. (Loren, I hope this is not too specific) For you Boxster guys the 3.4 Non-Egas uses the same computer as the 2.5L cars but a different mapping obviously. The Boxster 2.7 and 3.2 uses the Motronic 7.2 much like the 3.4 Egas no-shocker to you Egas guys. Please correct me if I am wrong on these claims. Thanks, D.
  5. Thanks for the information. I think the noise issue is the reason VTX pads are steeply chamfered before they are shipped as the picture that I attached shows. They should have just attached some proper shims to them and they would be fine. Honestly, the Textar pads are really nice on the street I just have to clean my wheels.
  6. The backing pads/pucks are adhere to the pad by adhesive, you peel off the wax paper and stick it to the pad, just like a sticker. I wasn't able to re-use the the old ones, as trying to pry them out and overcoming the adhesive more or less destroyed them. In anycase, I couldn't think of any adhesive I could use that would withstand the temps of the brakes without rendering it useless. I figured, if it didnt stick on, they wouldn't work, might as well do without them - or buy new ones. So which is the new design and which is the old design? The ones with the "weights" or without the "weights"? The pad area of the pad without weights looks bigger though. From what I recall from Physics in university, is that friction is not a function of area, only the miu and the normal force, but then againt that is classical Newtonian mechanics, perhaps too ideal for the real world? Look closer are the pads and you'll notice that it is an optical illusion...lol! Plus the compound or brake pad material has a bigger effect on the stoping power then the small differences in surface area. The friction area in my picture is of the VTX pad anyway not the Textar. The new design on the Textar pads has the same surface area as the original pads. The VTX pads are probably fine pads if you don't mind the fact that they make some noise and do not stop as well until they are warmed up.
  7. :) Yes. And no egg yolk. To let those who are not familiar know about the vibration dampeners on the Porsche here is some information. The factory pads have shims adhered to the pads. Mr. Fraser is referring to the separate vibration dampeners that pop, snap, click or attach to the pots in the caliper. These vibration dampeners are actually glued to the OEM brake shims during your Porsche’s assembly. You can replace the dampeners with new ones when you replace the pads if they are worn out. It is always a good practice to replace all shims and dampeners where available and applicable. Now, in the case of the VTX pads, they do not have the brake shims attached to them. The pot dampeners touch the bare steel on the pad. Plus the brake compound is harder and a different composite than the OEM or Textars/ Pagid...etc making a squeal. Yes, I could have made some shims and blah, blah, blah but why? I just spent $240 on brake pads they should be right when I get them. That is why I am relaying the information to you here in this forum. As far as egg yolk… The brake anti-squeal compound that some use on their break pads was originally designed because newer coatings were not yet developed on the shims to cut down on the squeal. When a person installed their shims they would coat both sides with this anti-squeal or seating compound. Because it was off white in color and has a sticky nature it is also referred to by older mechanics as "egg yolk".
  8. This is also the case with Bosch pads. They are Textar too. According to Pelican Ate, Jurid, Textar, and Pagid are all OEM brake pad manufactures. Which it is quite funny that my front pads came in a Pagid box anyway. I do believe my OEM brake pads were of an older design though and being ten years old they possibly started to deteriorate thereby causing more dust than normal. Albeit, there appears to be no alternative to the dust (v) squeal dilemma. As to the weights on the pads, I can find no information on the web. Logically they are there for to cancel out brake chatter but who knows really?
  9. To follow up on this post, I decided to purchase 18s with the appropriate sizes for 99.
  10. Does anyone know if there is a low dust and quiet pad for these cars?
  11. This is also the case with Bosch pads. They are Textar too. Here is a picture of my OEM pads compared to the VTX pads. The steel side of the Textar pad (Not shown) looks identical to the VTX with the addition of the vibration shim. you can see that the factory pads did not have the extra weights.
  12. What do you mean by couter balanced by the way? Here is a picture of the front OEM pads from 1999 compared to the VTX pads. You can see the extra weights on the pads.
  13. C2 MY99 The Brembo pads were quite dusty. I found my wheels covered with black brake dust after driving ~100 miles. VTX promised less dust but after I installed them they were very noisy at stops. The VTX pad does not have a vibration shim adhered to it like OEM. The VTX pad also stops better after warming up. Textars are quiet and somewhere in between the other two mentioned on the dust. They are not too dusty like the stock Brembo 996 pads but do shed some light brown powder after ~200 miles. Both the Textar and the VTX have provisions for wear sensors and are counter balanced (front). My 2 cents. D.
  14. What are the actual differences between the 3.4, 3.6 and 40th Anniversary 3.6 (Not concerned with GT3 and Turbo models)? Does anyone have all of the engine specs and details? This is what I have found to date on basic specs 1999 3.4 = 296 hp 00-01 3.4 = 300 hp 02-05 3.6 = 320 hp 04 40th 3.6 = 340(5) hp Additionally, many have noted that the 40th headers are different. Is this because of the heads? Does anyone have all of the engine specifications; from bore and stroke to camshaft lift and duration? Thanks, D.
  15. Just out of curiosity does anyone know what changed between MY99 to MY00 to gain the extra 4 horsepower in the 996? Thanks, D.
  16. Is there a forum member who lives in Southern California with a Porsche System Tool to enable my OBC and to recalibrate my speedometer? I am in Riverside, CA and will drive to your location. I will pay for these services with cash or beer or cash and beer; your choice.
  17. After hours of searching on this site I decided to start this thread. I have copious amounts of brake dust on the wheels of my 99 996. I believe my pads to be OEM at only 38k on the ODO. What is a low dust alternative to OEM? Thanks, D.
  18. This does not appear to be a popular topic. I'll post on the install in a couple of months. D.
  19. No service techs on Saturdays. Does anyone in Southern California have a PST2 tool on this forum? I would much rather pay a member if he or she is available. D.
  20. Oops, just realized the fourth stalk is just a rocker switch...lol! This is actually a very inexpensive upgrade! I'll call Porsche today to get a quote on enabling the OBC. Bill, I have to tell you thanks again. I didn't even know where to start searching on this one. D.
  21. Thanks Bill, that is what I am looking for. Now I have to decide if I want to do it the Porsche way or purchase a Bluetooth OBD II unit to use with my Kenwood... I guess it depends of the availability of parts. New four stalk units are probably quite expensive as well as dealer services.
  22. Thanks a lot for the information. That is exactly what I was looking for. I do not need my idle hands modifying anything unnecessarily on this Porsche but the devil in me wants to...lol! Knowing that this sensor was not designed for auto lights calms my desires. D.
