Default after switching to a chipped ecu car throws IACV code and idles speraticly

Hey guys whats up,

I just socketed and chipped my ecu let me give you the details. I have an LS motor that ran fine with a stock ls computer(P75) But then I socketed and chipped my P06 loaded it with a stock ls basemap. after switching the ecu the car's idle jumps up and down really fast and throws a code for IACV. what the heck, it runs fine with the other computor? I dont know what bin is on the chip (I didnt burn it)

What could it be

Well if it is ecu specific. There is a problem in the IACV circuit of the ecu.

Was this ecu ever converted to vtec?
