i've been doing a little research on which ecu to use for a dohc zc motor but i only ended up confused. they said the integra ecu is better because it runs richer and has a better air/fuel ratio. or the integra ecu isn't as good because it runs too rich. i also read that the zc is the best ecu for the dohc zc. so now i'm very confused and don't know which ecu to buy for my car. i can get a zc ecu for $150.
so if anybody really does know which ecu is better for my motor please help clear this up for me.

 

zc ecu is defintiely the best....if you can find one for a good price... 88-89 teg does the job.. runs a little rich.... other option is chipping a si ecu to the zc specs...

 

ZC for ZC the only reason not to go with ZC is the speed limiter I think 112PMH-if you go that fast-then you need to die

 

EDM PM7 from a D16A8, no speed limiter, but otherwise JDM PM7 is fine since its for the ZC too...

 

look for a zc ecu a little harder, ive seen them on ebay for 80$. i paid $40 an $20 for both my PG7's(89 integra) when i had my zc. make sure the ZC is the JDM ecu which i beleive the code is pm7. most people try to sell the ZC ECU as a pg7 which is the USDM 89 integra. a crx si will do the job, but pg7 is better. get a safc to help lean it out.
