I drive a 90 crx Si. When i blew the stock si engine, i replaced it with a plug and play, lthe SOHC ZC.

I think i read someplace that you can use a different, more aggressive ECU. I think it was supossed to come off of a first generation Integra.

So, yesterday Wednessday was my day off. I went to the junk yard and found an Integra with the ECU still in place. I bought it!! I can't wait to install it. but need your advice.

Any comments will be greatly appreciated.

 

pm5, pm6, pm7? i think its something like that. i dont know the right one though.

 

1st gen integra, i believe is pg7

 

I thought i read someplace that i could use the PG7. Is this true? If not, please let me know cause i am now a proud owner of a PG7. As far as my PM6 goes, I'll find out later on tonite wether it's been switched or not.

 

yeah, i think it should work. but, it has to be 88-89 pg7

 

thats the Teggie with the pop-up lights right? Hope this doesn't mess anything up.

I'm such an ***!! I don't quite know why i'm making such an issue out of this?Anyway, should i reset ECU before i do this?

And again.. I'ts a SOHC (Single-Over-Head-Cam) ZC.
Thanx a 1,000,000

 

you just spent money on something you wernt sure if it would work or not. you dont want to spend more money then you need to... so i dont think your an *** yet...

 

your fine with that ecu, im running it without problems at all.

 

make sure its from an 88-89 integra 5 speed. an auto will not work.

 

I can honestly say that my old SOHC ZC felt slower when itook out my PM6 and put in a PG7. Yea i know it was the "but dyno" but I know my car and it did feel slower. I even kept it in for a few weeks and checked my mpg and i was getting 5-7 less mpg. PG7 is only good for the DOHC ZC, not SOHC.

 

i'd say the stock ecu since the sohc zc is basically the same engine u had stock. the pg7&pm7 are for dohc zc

 

thanx guys.
I guess since you folks say it wont mess anything up, maybe i'll try using the pg7 over the weekend and i'll tell you how it went on monday.
laterz.
And thank you very much!!

 

Well did it work? I'm planning a sohc zc swap for my 90 si. With so many different opinions its hard to find the right answers.

 

Just keep the stock one n chip there. I wouldn't have spent on another ecu.
