I need the ecu now which is better? final answers plz 89 integ LS ecu for 100 bucks or 91 crx si ecu fo 125 bucks which which ? hurry hurryi got 45 mins to make up my mind.

 

anybody?

 

I would say that if the sohc zc motor is stock........then i would get the 91 CRX Si ecu (PM6 i believe) since the sohc zc motor is VERY similar to the D16A6 crx si motor. that's what my friend did when he did that swap in his 88 civic dx hatch, and it worked great.

yeah i was thinking same thing since my **** is single.. maybe if it was dual i would get a ls ecu hehe ill just stick with the si thanks guys

 

Go with the integra... it will run a little rich but it has a better fuel curve... and a higher rev limit.

 

just get the j-spec zc ecu. u will avoid the engine codes

 

Run the 89 Teg. The redline is nicer, and if breathing properly it does help the car.
This is from experience with SOHC and DOHC ZC motors.

 

Honestly, the PM6 ecu will give the SOHC ZC plenty of fuel.

There is no need to use the LS - and about the higher rev limiter? It's only 300 RPM higher. PM6=7500 rpm LS=7800 rpm

Just stick with the PM6 - that way you know you have a good solid ECU, the LS could have some glitches.
