Running 440cc injector with stock ecu... also when the car run fine or spitting, when I excelurate the engine dies ever timr... anyone knows what going on. I think it flooding the motor with gas...

jacky4566 Posted June 11, 2017 Share Posted June 11, 2017 So many questions... Ok first. If you want to stick with the stock ECU here is your new bible: http://datsunforum.com/datsun-fuel-injection-bible-200sx-280z-280zx-810/ Second. The stock ecu was never meant to run 440cc injectors so unless you know how to tune the Z31 ECU I would stay away from that mashup. Third. How are you measuring 0psi fuel. its not possible to run with 0 psi so something is wrong. Quote Link to comment Share on other sites More sharing options...
NewZed Posted June 11, 2017 Share Posted June 11, 2017 (edited) Edited. A moderator must have deleted my other post, with its good information, in the other duplicate thread. So the comment that was here just looked like random rambling. Context, moderators, context. Consider all...
