Hello, I recently finished my na-t setup ( besides my standalone im trying to get )
Im wondering if im wasting my time with trying to tune with my safc or not.
My fuel system consists of a 320 LPH fuel pump, 800 cc injectors, and adjustable FPR.
I noticed when ever i see threads regarding na-t supras with safc's they seem to never go any larger than 550 cc injectors.
Im guessing the stock ecu even with the safcII just can't handle the 800 cc injectors. For the most part under throttle the car sounds good, but idle is nearly impossible when its warmed up.
Im hoping there is nothing wrong mechanically on the car but i've made sure everything is hooked up, i have my timing on 10 BTDC the only thing not connected is the acis valve which i welded in the closed position.
What i noticed is the car on open loop ( cold ) tries to run pretty smooth, But soon as it is closed loop ( warm ) it just wont idle.
Is it possible i simply cannot tune with the safc with what my fuel system is ? or do i just have something wrong ?
I've seem to master this safc II on my 240sx but i feel like the stock ecu is not capable of getting a smooth idle with the fuel system.
Thanks for reading
