Evan morris Posted May 7, 2013 Report Share Posted May 7, 2013 I have recently built an rb25de with itb's from the rb26det and i am considering the g4 storm but finding little to no info on the system running an itb setup. Does this ECU have any features to properly run a set of ITBs?

Simon Posted May 8, 2013 Report Share Posted May 8, 2013 No problem at all to deal with ITBs Typically you will configure the ECU to have its main fuel table tuned on TPS and use a 4D overlay table spanned on MGP to compensate for changes in VE with boost. I would suggest if you can make it to the Xtreme it will give a better result as it can then run sequential fuel. And allow for slight trimming of cylinders if the ITB's are not set spot on.
