Nismo Rb26 550cc Injctors In Rb20

[Ceffy_SA]

Hi Everyone,

Just wondering if i would need a resistor pack installed with my RB20 as i have just bought some GTR 550cc injectors that have supposedly come from a RB26, usually i would assume yes i would however i am running a AP Engineering RB20 power FC instead of the standard computer, i have searched but couldnt find an answer.

Any help is much appreciated.

RB20 ECU expects high impedance injectors, RB26 injectors are low impedance, so yes you need the resistor pack. Unless the AP Engineering has some sort of switch to switch between high/low impedance, but I doubt it (I've only ever heard of it the switch with Megasquirt ecus)

the ap engineering rb20 PFC behaves the same as the stock ecu, that is, it doesn't know what injector type you have, it assumes stock injector setup

it can support larger ones etc, but they must be the same type, that is, impedance, voltage etc
