Default GREEN/BLUE DBC PCM (Where?)

I Know which pcms came with IAC drivers. The trouble i am having is finding someone who sells them with a flash and tune! (green/blue w/ iac driver)

I currently have one thats been flashed (used . But my car will still not run correct. Its a swap and went over everything and cant get rid of my MAP codes p0107 p0106. My spark advance is 20+ at idle and the 02s are jumping like crazy. Map is good. ready correctly.

Its only been flashed for vats egr rear 02s. Im wondering if it need to be set for my exact motor (lq4).

So based on this im going to just get a new pcm.

(runs when it wants, shitty idle, stalls when given gas, wont pass 1500 rpms)
(new o2s, iac valve, tps sensor)

Read somewhere a guy had almost the same symptoms. Except with a MAF code. Turned out to be the CMP sensor. Ill give that a go for now.

Open the PCM and check for IAC drivers, that's the only way to know for sure.
However the problems you have can also be caused by a shitty tune or mechanical problems. I highly doubt that lack of the IAC is causing all that issues.
