Has anyone ever tried to get IAB's working with Crome Pro using the P30 ROM? I know that the IAB's will work using a P72 ROM but that ROM does not support ITB's, only the P30 has ITB support that I know of. Any Crome info or suggestions would be much appreciated.

if you have ITBs why do you need the IAB functionality? the intake that has the IAB setup would be removed when you go with the ITBs.
or are you simply looking for another output to play with?

No not for output..... your right I am going to be installing a set of GSXR ITB's and I realize that I will not be using the actual honda IAB's. I need the IAB control because I am using the GSXR's Secondary Throttle Valve System. I figure instead of having to go out and buy a GSXR ECM and wire it into my Accord sensors. I could make the IAB system work to control the secondaries on the GSXR Throttle Bodies.

Would enabling VTEC in the Crome P30 ROM and using the VTEC solenoid signal to run the IAB solenoid work? I'm thinking that will be a cell nightmare where the IAB is only one pin and the VTEC is two. I would have a dead signal possibly throwing a cel where I'm not running a VTEC head. Is there anyway into tricking the ECU into having VTEC pressure? can I run a switched (engine running) 5v signal to that pin?

I was finally able to figure this out and get the pin swap to bypass the VTEC pressure switch. I now have the VTEC signal from my ECU to power the Suzuki STVS servo. Never-mind using the vacuum driven cumbersom Honda IAB system, that would just be another source of vacuum that I would need to have available
Now all I have to do is figure out where to set my VTEC engagement point for opening the secondaries... that will come after a few WOT runs on the dyno to see where it needs all that air. thanks again for all the help!
