Hello 3sgto
I'm posting up here because I'm stuck (still) with this flash ecu. I replaced the clutch in my 91 tt GTO, and am now working through the 400 mile break in. I'm hoping to get the small issues sorted out now, so once I do hit that 400 miles, I will be able to start tuning the car and having some fun with it. I really have 2 issues:
1. Evoscan does not register any fuel trims. At all. They read 0 from start up to shut down, no matter what I do. I replaced my O2 sensor, re flashed the ecu with the second O2 periphery on, and off, with no change whatsoever. The length of drive doesn't make a difference either. I've been out for up to an hour at a time and still nothing. I have a battery disconnect, but have left it on for the past 2 weeks and that hasn't made a difference either.
2. My idle will NOT drop below 1000rpm. The only time I'm able to make it drop to the 650 it's set at in evoscan, is when I manually put it into SAS mode, and then it will idle down, but as soon as I uncheck the box in evoscan (or unground the pin under the hood) it jumps back up to 1000.
Can anyone help me? I've been seriously considering wiring in another O2 sensor for my PNP ecu, but I can't find a pinout anywhere that labels where everything needs to go; and will that even help me, if I do get it wired in? I am getting realy disheartened with this whole setup. If I put the stock ecu back in, the car runs like a champ. Seriously, I'm willing to paypal or e transfer money to anyone willing to help. Thanks
Kyle.
