I hope what I did above was ok because that is what I did and just started the car again. I updated the VE table to the new one that bob put out. My car runs like crap at idle. I have PTE 680 (like 650 injectors) and I had my mainscale set to -44. I have now made my mainscale like -40 and have tried to add 15% at low and mid at 400,800 and 1200 and my car still idles lean and is bouncing up and down.

Also, when I tap the throttle, the RPMs drop super fast and the car will sometimes die. I have adjusted my tps to .45. I am unsure of what to do now. There is so much information spread throughout this thread, can someone give me some hints on what to try next. As of right now, my car idles like crap and I doubt it will drive very well. Also, even though the wideband says it is idling lean, the car smells super rich.

You have to reflash the maft-pro unit, too. There's instructions for this somewhere.


You have my problem. My AFR used to read lean but it litterally dumped gas out the tailpipes...or it used to anyways. Set your TPS at .60 volts. Also, try driving the car around to warm it up. That helps mine A LOT. I've checked connections, sensors, leaks, all that good stuff. I'm thinking that maybe I have a bad ISC, so I ordered a new one, but i haven't heard from the guy I ordered it from yet, so I'll post up with those results.

Also, write your own VE table. That's the best way to get it to do what you want.


edit: forgot, i lowered my base fuel psi...and compensated with the mainscale. That helped somehow. I think it prevents a little of my decel mode issues.
