Would jus changing out my ECU give me more power or nything, without doing a motor swap, maybe be a dumb question but it jus popped in my head and thought it would be a good idea. If it can be done what would be a good ECU to swap for an 86' CRX Si.

 

if its vtec try the 90-93 gsr and if non vtec try the ls

 

don't listen to him. the 92-93 integras are obd1. You'll need an obd0 computer, but honestly I don't think it would benefit very much.

IF you have other mods, like intake, header exhaust, and a cam, then maybe you should look into a way to tune it. Then you should get a 90 or 91 civic computer, since it's chippable, an have someone tune it for you.

 

I gotta CAI, and a cat back thats not to moded but jus a lil, its the factory EW3 1.5. so if I get the ECU outta 90-91 civic? Would it be "plug in play"?

 

I've got a PG7 ecu from a DA teg that will work. It runs a little richer and has a higher rev limiter. It may not be a huge improvement now but if you ever plan on boost or nitrous it'll work great. PM if you're interested.

Jus tell me the least you'll take. And we can go from there.
