d16/ZC what ECU to use?

[importgod94]

i got a 90 civic with a ZC swap and i need to know what ECU to run with. NOT oem or STOCK.

P.S. will a PG7 work?

ne help is apprecitated. thanks

i think an integra ecu... not positive

what ZC are you tlaking abot?Is it DOHC, if so you have 3 choices.

First is the 88-91 Si ECU, first gear pulls good but lags in 2nd and 3rd.

Now there is the 86-89 Integra ECU, i use this ecu in my dohc zc swap and there is a big difference between this and the SI.Mainly because the si is a single cam computer so the fuel maps are less aggressive.With the Integra 2nd an 3rd gear pull very nicely.

Now there is the JDM ZC ecu which is perfect if you have the DOHC ZC tranny and the gears are for this ecu.

You also have the option of geting your computer chipped.I would rec. www.zdyne.com for this.

I just have to clarify something here... the PG7 from 1g integras... you can only use 88-89 PG7 as the 86 & 87 uses a vacuum advance distributor... will not work with 88+ pgmfi

the best ecu to use is the 90-91 crx si. i have the same swap in my crx, and if you dont have a tranny yet use a dx. lot higher gears works awsome.

Thanx for catching my mistake yea they do have a vacuum advance distributor.

Also 90 rex, run a pg7 and then you will say the si ecu is crap compared to it.There is one problem though, this ecu does cause you to run a little lean.I use to notice this when i first started my car.So i just turned up my fuel pressure about 5lbs to compensate for it.Trust me, with this ecu an a little more fuel, you will feel a good increase in power.

I raced a 96 gsr with a few bolt ons an stayed even after he caught me in 3rd gear.After his third gear we were bumber to bumber with no one pulling ahead.And all i have is the pg7 ecu,bumped up fuel pressure,intake, and i'm still running the stock dx exhaust manifold.When i get my headers an piping, i'll be able to crawl away from gsr's.
