Could I just run an integra ecu for this? the one that came with the zc motors, since the p29 pistons came from a ZC?

 

You could use whichever ECU you want, PM6, PMy7, PG7. I dont see where changing the pistons would require changing an ECU that is on a stock program. I'd get a 91' PM6 and run a program on it to tune.

 

Well you are bumping the compression from like 9:1 to 11.?:1

So the increase in compression wouldnt it be safer to run an integra ecu than the stock 108hp pm6?

Yes tuning would be best, but wouldn't the integra one be closest?

 

yea 88-89 pg7 ecu
