Just found out that the iacv is disabled in the ecu. I'll turn that on later and see what happens.

Noticed at idle my iacv duty is like -38 % and no matter low much i change the iacv duty table it wont make it go down. As it warms up it keeps going into the - more. I have the duty at 0

Then why am I having so much trouble getting it to start? If I give it gas to start it then let off it dies. But if i hold it around 2k for around 20-30 secs and let it off it will idle.

does your boost gauge read vacuum? Is it stable or does it bounce around? what are the readings at idle?

I dont have a boost gauge, but I can log it and tell you...

Did not do the valves. The set screw on the tb was holding it open so it was idling high. I drove it around some and it didn't die. Its idling around 900-1000. But its still only pulling like 9-11 vac

do the valves when you can. I bet that is part of the problem. I was looking over your log, you need some part throttle tuning done.

Base fuel pressure of 38..... That's a little low for any injected system... Does the wideband show that the afr during this startup is okay? A few weeks ago I saved a mechanic alot of heartache diagnosing a no-start: the fpr was bad yet letting 42psi of pressure in the rail, yet, it wouldn't run until I told him to put his smog clamps on the return line.... Fired right up. Just food for thought.
