Hello,

I'm wondering which ECU I should get for my '88' CRX Si which has a ZC enginge installed. There's a guy on the board that's selling a ZC ecu for $125 should I get it?? or should I just buy a '89' Teg ecu for about $150 from a used parts place.

Does anyone know which ECU will give me better performance? ZC ecu or the '89' Acura Integra ecu.

thanks in advance......

 

I'm pretty sure the zc ecu will be better as I think it has better mapping for fuel and slightly hight rev limit

 

I'd get the ZC ecu. Be aware that it has a speed limiter around 112 MPH.

How much different is a '89' Teg ecu ??? Is the speed limiter higher than the ZC ecu of 112 mph ???
A guy here on the board just offered me one for just $50 I guess if it's legit then I should go for it right????

Help me out guys....

 

As far as I know the Teg ECU has no speed limiter. I had one running my ZC for a while before I went with a Chipped PM6.

$50 is a pretty good price for a Teg ECU. Make sure its a 88-89 model if this is going in a 88-91 model.

 

we have run both the PG7 (integra) and PM7 (ZC) and find no difference at all in how the car runs - get the integra - fuel cut-off is same on both at 7500

 

$50 is steep. I can get ECU's all day long for $25 at U-Wrench-It in Kansas City.

 

get the ZC ECU, it's the correct ECU for the engine..... I've seen many a teg-ecu'z ZC cars have lots of problems...... running rich and frying dizzys......

 

i have a sohc zc in a hf with the orginal ecu. The hf ecu has been programed by jet but it still floods and doesn't run exactly right.

I dont see how that would happen. The PG7 ECU should run a little rich on a SOHC engine, seeing as how its made for a higher horsepower DOHC engine. I know i'll probably get flamed for this, but you know essentially, the D16A1 and ZC are *VERY* similar. The PM7 would be the ideal ECU, but if you cant get a hold of it, a PG7 will still rip major ***.
