Picked up a cheap mace 25mm plenium spacer, goes well, LTFT went to average of about 50% Lean so it's increased the airflow by a huge amount, this is on a stock VS V6 with CAI and Pacemakers, so im recalibrating my MAF again.
The trouble i have though at the moment is the need to change the park position of the IAC, because now when i start it, it quickly jumps straight upto 1600rpm because of the bigger plenium volume and takes a few seconds to come back down, so does anyone know where to start looking for this? I notice the $11 vr xdf has it.
Thanks Guys

un-tested in a car but give the latest v1.10 a try, bottom of the tables list theres some IAC stuff defined now.

Re: 1.08 $51E XDF IAC Park Position Location?
that would be good, i need to change my IAC settings cause it revs to high when it first starts, i think due to not having a/c, power steer etc load on it.

just did a quick reburn and test in the carpark at work seemed to work fine, still have to drop it a little more but it only reved upto 1200rpm. Will check it again in the morning from cold, I used these values for the IAC Park during crank vs CTS

wouldnt a simpler solution be to back off your throttle stop screw?

Re: 1.08 $51E XDF IAC Park Position Location?
yeah thats my point..... its expecting the IAC to be at a certain point on startup, but your throttle stop screw is too far in so the IAC needs to close a long way to bring the idle back.

yeh fair enough, hot and cold are a bit different though so it would help to a degree
