Power FC tuning with ITBs, share your knowledge

quick question

i have ep3r with air filter, and soon to have cat back exhaust, what will i need to eventually run itb's??
also how loud is it or everyday driving??

i made more power out of ITB, but then again it was a stock ECU stepping up to ITB + ECU, so can't be sure that i wouldn't have gotten them just tuning the ECU on it own

Yeah but you are talking about a factory car that has come with ITB's and the requirements, ECU and is tuned to run them, its a different story when you are putting ITB's on a motor that hasnt come out of the factory with them, if you get what I mean. Im trying to say for someone that wants to put ITB's in, do some motor work before you do to get the best result with ITB's, not just put them on a stock motor. Because the motors that did come out with them were specifically made to suit that setup.

I'm on holiday in sunny Gold Coast atm and don't have access to my tuner, does anyone know if it is possible to tune in this way with the power FC?

Any other advice or thoughts with regards to ECU tuning for a daily driver with ITBs is welcome. We're still in the process of improving drivability and fuel consumption :)

It can be done but to be honest it is bothersome to tune as FC is MAP sensor tuning.
Your advantage here is the vacuum block you already have with IACV attached. (OER throttles from memory)
With a few changes & lap top software, a reliable responsive tune can be had that will deliver both good driveablity & reasonable econnomy.
It won't be a cheap tune as it takes a while to get right.

That said, if it were my car,
I'd ditch the FC & use an S300 (Hondata)

Thanks for your input TODA AU. So anyone want to buy a power FC, and when are you heading down to melbourne to tune my car?
