need advice

[tintoy]

Sir i just installed an evo3 609, 510cc, evo3 fpr, small 16g and evo4 fuel pump to my jdm 1988 vr4. And I'm still running the stock 8618 ecu. I'm running reach or lean? Do I need to replace my ecu to suit mod? Thanks.

you need to get a E-PROM ECU with a custom chip to suit your needs or you need to get a Wideband gauge and a tuning devise, i.e. - SAFC or DSMLink. the car will not run properly with just throwing in a different MAS, FPR and injectors. the turbo is fine to just be put on, but the fuel pump you might want to rewire.

Fuel pump rewire done and got a SAFC. Just need a wideband guage. Thanks for the advice. /ubbthreads/images/graemlins/smile.gif
