550cc injectors driven by j-spec ECU

Iam thinking about getting 550cc injectors aka euro/uk/us spec injectors. i will obviously also need to either get a resistor pack or build one myself. my question is, will there be any problem running the injectors with my ecu (j-spec)? reson iam asking is due to me digging abit in the cylinder head, iam bought a mines ecu and some other bits improving the flow. and iam getting abit scared that i will need (god forbid) lower my boost pressure due to not have enough fueling. (also i dont want to increase my base fuel pressure usinga tweakable FPR or use a progressive FPR)

 

if anyone have any ide how to wire in the resistor pack aswell please share.

 

Cheers

Yeah thats what i thought. Well its out of the question i guess. as i dont want to fiddle with piggyback systems. maybe its possible to exchange any of the vx-rom for running 550 injectors?

 

As i want to stay BPU and dont want to have a standalone ecu system iam guessing i will need to put down the boost if i see it leaning out :( i guess i could squeese abit more out of the j-spec injectors using a progressive btr but i would rather not use it tho.

 

thanks for the info tho heckler! apreciated

 

regards

johan
