Awesome! This makes me wonder if there's something wrong in the math I did for the AEM 5-bar. All initial testing was fine....sorry man Glad you didn't give up and kept pushing forward! Good work! Now go enjoy the car

Im confused with what your asking... do you mean what was my TPS code? If so, it was P0121.
Something about TPS range. Upon adjusting it, I got a P0122 which meant reading below threshold or something. But all went away after I adjusted it so that WOT reads exactly 5.00v
Closed throttle reads around 0.45v-0.47v. I've read that it should read 0.5#v-0.72v... so I'm not sure if this is ideal.

Apparently some of the lean issue has come back even with the 4Bar Omni Map Sensor. It definitely helped... but it didn't fully solve the problem.

Something is telling me that my boost controller is messing with me.... When I'm at low RPM and I fully floor it... as I'm building low amounts of boost... (1 - 5psi) if I back off of the throttle slowly... at about 90ish percent throttle, my AFR will go up a point or two, and the car will feel like it got a 50 shot of nitrous... it's as if it goes to a different load cell of timing/fuel or something. Maybe it's the ECU that is screwed. Once boost hits hard, it's fine, but the daily driving is making me lose my hair (and my clutch) The word aggravation only skims the surface of what I feel with this car right now. Nothing ever works right and no one wants to do anything/make money/or deal with it. These are the types of problems that make me want to sell the car. It's a damn shame because everything in this car is so bad a$$. wish I knew what little thing I did that made it go wrong.

I wish there were tuners out there that gave a f#$@ and took in a car and saw it through to the end of a tune instead of kicking you out the door to make a quick dollar for a WOT tune.

I've had my motor built for over 12k miles, and I've yet to have a finished tune. I don't care if a tune requires more parts to be swapped out for compatibility... I just want the g0d damn thing finished... (end rant)

Hows your AEM treating you? That AEM drove better in my car than this stock ecu.. I should have never bothered. I guess it all just comes down to the tune. Maybe I'll fold and get an AEM v2 and hope that id drives better than the v1. Or just trade my car for a stock evo and leave it the F alone. This is getting ridiculous.
