  1. Engine is largely stock. So for a street car, would the ECU seeing only 78% when pedal is 100% depressed be an issue?
  2. Have been using my Durametric to try and isolate a misfire on my 1999 (DME 5.2.2) cable throttle 996 C2 (race car) which has a RoW tune. Unrelated to that testing I noticed the recorded Throttle Plate Angle when pedal is fully depressed (WOT) is showing 78%. A visual indicates my throttle body plate is easily opening to 100%. Do I need to worry about the DME getting this 78% signal when in fact it is 100% or does it calibrate itself but not show a calibrated value in the software?
  3. Code value, yes. That's what the Durametric shows, as per the screen shot.
  4. thx, Fan is long gone. Would you happen to have any guesses on a range of resistance values that I could test through? I can probably come up with something variable to test with and then later swap out with a final resistance value as "the fix". But I have no idea what range to start with given that I have no fan here to measure.
  5. Porsche 996 C2 - 1999, M5.2.2 DME Engine fan removed many years ago during conversion to a Grand-Am Cup race car. Always ignored this error as there are no shorted wires to that fan. The wires are independently taped up and tucked away. I figured it would be nice to get rid of this code over the winter. How can I resolve this?

  7. Anyone know what type of sealant this green stuff is?
  8. Widening your track is a basic competition change made to many cars when raced. A wider track will lower the roll center therefore reducing understeer. A wider track will also reduce the load transfer to the 'outside' tire which will reduce the loss of grip from the 'inside' tire. Look at the history of Porsche base models to their evolved cousins... 924 > 944, Carrera > GT3RS, etc. Now unless you are tracking the car you probably wont notice the difference. However if you are tracking (or racing) the car, every incremental step toward an optimum setup is a step worth taking.
  9. Is there a "shadetree" method to determining if the resonance flap on the 996 intake is opening at the correct RPM? I can test the solenoid that triggers the vacuum but I want to know if the flap is actually opening @ the correct RPM.
  10. >> it looks like the throttle body is jamming or something. This would be independent of RPM. Don't tear it apart yet.
  11. It may depend on where you plan to move. The easiest changes will be those related to emissions. Every state has different requirements that need to be met. In fact, here in PA even different counties have different requirements. I'm no expert but other than emissions, I think that by 2003 Porsche was building the cars all about the same. So things like safety glass, bumpers, etc. should all be the same.
  12. 88k ... just pulled the original 3.4L engine last month after finishing my LNE / JE / Carrillo etc build. The new motor is in the car. After inspecting the old 3.4L, the only signs of wear I see are on the 1-3 cam gears & lobes. This was due to an intermittently failing Variocam solenoid that was left un-repaired for a few years. The RMS had started leaking but the IMS was in good shape for its age.
  13. Thanks Loren, I was wondering why there was a TPS on the pedal in my car which has a cable throttle. You would think Porsche would have had a non-egas pedal designed for the early Boxster and 996. Regarding the cable routing, I was more looking for info on how it lays over the top and back of the engine and down past the gearbox. But no worries, I finally figured it out tonight. It is VERY specific about where it is routed or it gets too short. You have to fish it though the coil on the clutch slave line or else it bends too far to the side and takes up too much slack. Then clip it into the plastic clip that is bolted to the top two bolts of the diff housing cover. After that its a straight shot to the front section you have pictured above.
  14. Hello, I'm looking for a Diagram or Info on routing the throttle cable? Recently had the engine out and upon reinstalling I'm finding the tab where the rear cable section (to engine) connects to the front cable section (to cockpit) doesn't have quite enough slack. If I reassemble correctly it keeps the throttle plate cracked open resulting in a 3000 RPM Idle! LOL I have the Porsche factory PDFs that are floating around but have yet to see the cable routing & adjusting info. Currently I have the cable routed up over the manifolds and down the back next to the trans. Technically its laying on top of both resonance pipes and then drops down the back. Thanks in advance if you can help. - Bill
  15. Thanks Loren, Just out of curiousity, do you know where the engine compartment temp is measured? - Bill
