I used to have just the wiring diagram for PSE of 997.1. Since you need it for a 997.2 I advise you to keep looking for it.
d0lph1n started following PSE button wiring ? and What's the location of "CU On Board Comp. Network"
For a 2005 997 C2, where is the "CU On Board Comp. Network" located and what's the easiest way to access it? On the wire schematics I have, it shows it's located on the driver's left side. Any visual clues?
Can anybody please confirm, is the Sport button's ON/OFF LED connected directly to DME or not? On my copy of 911 2005 Sheet 4 "CU CLuster / Combined Steering Column Modul": I'm guessing, the Sport Button's LED (A12) - On Board Comp, Network Control Unit 2/E10 - 397 Ye/Ye 0.35 - NR. GM Also, what's the easiest way to access this wire or what's the exact location of the CU On Board Comp. Network?
I appologize for my previous chaos. I have a SPORT button, part of the Sport Chrono...not a PSE button. I'm really sorry. I've been reading lately the PSE install pdf which has the instructions for both..Sport Chrono or PSE only. I've updated my previous posts. Anyway, do you have the DME pinout or schematics?
But the PSE ON works accordingly: - better throttle response - faster gear shifting - gear shifting at a higher rpm - full pse solenoid control - the steering wheel is more responsive - more aggressive engine break (i think) etc In reading your various posts I think you might be confused (or I am) about your PSE. What you described above for "PSE ON" is not PSE but "SPORT" mode. You say you don't have PSE mufflers so I'm thinking you don't have PSE at all. One external indicator would be to look at the tail pipes - do you have dual quads with the inner pipe with a smaller diameter than the outer pipe. Yes you are right...I made a huge error. I have a Sport button, not a PSE button. What I'm trying to do applies to either PSE or Sport button.
It turns on/off with the Sport button. No idea how it does the modulation. I don't have access to Piwis or Durametric. When I had access to Duramteric V3, the only error was CAN BUS display c112 in the gateway module..i think Also, When I purchased the car, I paid for the an independent Porsche mechanic to inspect it. All the issues found (the Sport button wasn't working at all) including a DME issue were fixed by the dealer via a Porsche dealership. I was able to double check it by asking the Porsche dealer for the repair history. It looks like at that time the dealer replaced & programmed the sport button control unit..for $1000.. Part number 997.618.516.01 was replaced
But the Sport button ON works accordingly: - better throttle response - faster gear shifting - gear shifting at a higher rpm - full pse solenoid control - the steering wheel is more responsive - more aggressive engine break (i think) - open PSE valves etc
I've been driving all day with the solenoid disconnected. I did a check few minutes ago, the obd scan reports zero errors. Re: the wireless solution, if the Sport mode switch is not connected directly to DME, I might integrate it with my idea, if I'll be able to make the relay control the wireless remote. Having an extra button to push is no good ;)...for me.
I see, I'm familiar with the wireless solution but I'm not familiar with a DTC fault. A lot of people recommend disconnecting the wire harness from solenoid. Anyway, as I mentioned earlier, my goal is to install a relay that does the followings: 1. Detects PSE or Sport Mode button ON (Ex: PSE button's LED light) 2. Switches off the DME connections to solenoid simulating a solenoid's harness removal. If what you say about DTC fault is true then instead of switching off the connection to the solenoid, the relay could swithc it to a fake resistance (same value as solenoid's). No need for a wireless or wired 12V alternative circuit. My car 2005 C2 (no-PASM), came from factory with the Sport Chrono package (Sport button) but without PSE mufflers, solenoid etc. What I'm trying to say, the PSE worked fine withtout a solenoid until I purchased it and installed a solenoid and PSE mufflers etc.
I think I need the Sport Chrono install pdf. Do you know where I could find it?
My goal is to tap into to PSE or Sport mode switch= > install a relay; if PSE/Sport button ON the relay will disconnect the PSE solenoid from DME...so the PSE exhaust will remain ON all the time, as long as the PSE button is ON.
Year and model is always helpful. You would need the car's wiring diagrams. The Bentley manual has a set for most 996's. It's a 2005 C2, Sport Chrono package. I have the 101 Projects book, I'll check it later. Meantime, I've checked the 996 2002-2205 which is supposed to have the same DME version. I couldn't find the PSE switch pins. The car came with factory installed Sport Chrono but without PSE mufflers. As far as I understand, the mufflers were not available at that time. I installed the mufflers (2nd hand) & wiring+valve (new). I'll PM you asap.
Is the Sport or PSE button connected directly to DME? Where can I find more info about the wiring?
I hope you are right. I need to buy or borrow a durametric asap. If possible, I would recheck the car with a more current version of the system, Reason I say that is there was a rash of Chinese clones of the Durametric system, all of which were old versions (current is 126.96.36.199), and many of which were questionable to the point of actually damaging some cars. So unless you know the provenance of the system you used, I would recheck it just to be safe, and because if the code is real and live, the next moves will be more complicated and possibly expensive.
No aftermarket audio. I don't have any problem that i'm aware of. I had an ignition coil short few weeks ago and a drained battery. But all the ignition coils, plugs and 3 ignition coil connectors have been replaced. The battery is fully charged.
