Hello



i will be doing a rebuild on my gen 1, skimming and porting the head, large air filter, 252 lift cams and a tubular manifold and performance system. do you think the standard ECU would be ok? if not any recommendations?.



Thanks

 

Will it run, probably. Will you actually see decent gains, probably not. If you want to maximize the power out of those mods your going to need to tweak those crap stock fuel/spark maps if possible.

 

cheers for the reply but what tweaks to the fuel/map will i need to do to get the best out of the mods

 

That depends on what hyundai did with your stock stuff. You would need a wideband to see whats going on with the air/fuel mix and a dyno to see if you could gain any power from tweaking the timing.
