RB25de running ITB's

[Evan morris]

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?

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.
