Ok so with 300zx's when you install an aftermarket ecu such as JWT the AIV's are deleted in the code somehow and smog is unnaffected. Do they lean out the idle portions of the fuel maps or is there actual code to remove the AIV? After some searching on
www.twinturbo.net removing the aiv's without an ecu upgrade it is common for the car to stall while decelerating as well as running fairly rich around idle. That sounds like a similar problem many sr swapped cars have. So if anyone has any insight to this please let me know so I can alter the ecu to adjust for aiv removal. Thanks in advance.
