Any codes or comms to the ecu?

This was a new version from europe. My file is getting loaded for Steve on this go round. Zero problems with my file since day one.

Looking forward to next week.

**speedtrapped** · October 22nd, 2010, 17:40

well, sorry I didnt get back in time....Ty Dave for the color. Yep, we charged her, tried to run codes, nada. then we took ecu off harness, reinstalled and turned her over-ran great drove her again and she drove wicked, perfect. w/ my mechanic in car, drove back to my house turned her off, pulled key went To restart, nada,,,turns over but no fire. pulled ecu and reinstalled , bamm started right up. we did this 4x, each time we had her running, he did pull codes, cleared and pulled....no problem tcu, no immobilizer, something 30(sorry blanking right now)....each time we shut her off she would not restart. as Dave stated shipped her off to EC for a reflash. Will keep ya posted, should have it back tues.
TY everyone
Stephen

Well, that's good. Software bugs can always be squashed. Dumb question, but did you try just disconnecting the positive battery lead and shorting to ground to ghetto-reset the ECU? Thinking that by pulling it you were possibly just resetting it.

Either way, sounds like some rogue code in the tune, a ghost in the machine which will hopefully be purged on the flash. Before experimenting with alt tunes, it's ideal to have a second ECU coded to your car. Unfortunately their aren't many out there.

Ditto...........

**speedtrapped** · October 22nd, 2010, 20:15

live and learn....I actually thought I was getting Daves, but I did not, no big deal.

**speedtrapped** · October 25th, 2010, 16:31

Ok so I spoke with jerry this am, he has my ECU-he sent me a photo of my board, turns out a jumper was dislodged, stock on the epoxy, he is resoldering it. He has to check the otherside as well, fingers xxing.....I emailed Dave the photo, because I dont think I can post at the office....

**marklar182** · October 25th, 2010, 16:55

I take it this was probably from shipping, correct?

**speedtrapped** · October 25th, 2010, 16:57

i gotta assume-but Jerry did note, that back in the old days when an ecu was flashed, this jumper would be removed for flash then resoldered. I know duckwingduck had the engine stock, but maybe 1st owner had it flashed? If not then yep, likely box saw alot of tossing and bouncing around

**SteveKen** · October 25th, 2010, 17:44

What's the history with your ECU? Please excuse me if it's already been posted.

So, you sent it somewhere for a reflash? Got it back, it ran once and then will not run again?

If I was messing with the tune and did a reflash and this happened, then I would suspect that it's some type checksum error.

In other words, the car runs fine (or through one cycle) until it re-verifies that things are as they should be and then locks down?

Does this make sense?

I was thinking the same thing, that or a register. But it seems it was just a simple jumper that came loose.

Probably the 20" rims and KWv3 settings...

**speedtrapped** · October 25th, 2010, 18:04

I was under the impression the car was stock as per last owner(duckwingduck). I wanted to flash my ecu/tcu. Installed both when units came back, EC and MTM. On maiden start, (drove car prior, no issues, even had the TB/75k service, no codes) car ran like a raped beast. Shut her off went to bed, woke up nada, crank no run. check relays, and connections, everything checked. Had my audi mechanic friend make house call. codes werent coming in, battery was reading low voltage. Then he removed ecu and plugged back in and bam, started right up. Huh? So I thank him, and said lets turn her off and start again, just to be safe, nada no start, crank but no fire. we did this 4x, same result, unplgged and replugged started-turn off key and restart, nada. Jerry @ EC was at a loss, but has been great to deal with. He got the ECU this am, opened it up, found a jumper that had fallen off, resoldered, bench tested everything, no issues! In transit back to my house tomorrow-cant wait! Keep you all posted. Ty

Ben u might be on to something, my car rides rails and any little bump at hi speed and the front end bangs, not literally, but u know what I mean

I remember riding in it once and there was that type of road surface that is similar to when a dirt road is dry and driven on alot with the ripples/ridges/waves.
It was in a corner and it felt like the front was skipping/sliding over the top of the crest of each ridge/wave.
It was a very odd sensation - on power - turning - skipping/sliding - yet gripping kind of ...
It was oversteer (front pushes and rear is straight) or understeer (front grips and rear comes around?)

edit: and I wasn't driving....

**speedtrapped** · October 25th, 2010, 18:16

man I luv the rims, but now almost tempted to go 19" with a softer type profile(tire), any way to soften the KWv? I luv the handling....

Greg said the same thing about going to a 19"
Search for Headshot's modification to the shock tower so as you can change the settings without removing big pieces of V8 or suspension pieces - VERY nice DIY with photos
