H22 ECU

I am running an OBD1 P72 ecu right now for my GSR. I was just wondering if it would be any benefit to put a H22 ecu OBD1 in instead? Would it even fit?

No benefit at all, in fact it's a downside because the H22 ecu looks for an EGR valve that doesn't exist on the GSR and thus you will get a MIL code for it (CEL).

unless the GSR is chipped, its probably a poor match for the H22 motor. Chipping it would be both more cost effective and more benefitial than a P13 H22 ECU.

EGR valves are required for emissions. How does a P72 not look for it?

If the ECU isn't programmed to run an EGR system, it doesn't run an EGR system. P72s are not programmed to run an EGR system

Weird. I was under the impression that most newer (90+) cars needed to have some sort of exhaust gas recircularion system in order to be emissions-compliant.

What if it was a chipped P13 running my GSR motor??

As radnub has mentioned, unless the program specifically eliminates the EGR information from the said program, then it's no benefit.

If it does, I sure hope your GSR is built up, because the 2.2 maps are not going to work well for the 1.8

huh.....good to know....... <_< Glad I asked first.

Doh! I feel like a fool for misreading the question!

H22 ECU won't help a GSR. Chip the GSR ECU.


dohcvtec_accord: re - emissions... LEGAL compliance vs sniffing compliance vs looking compliant are all different. There is almost always more than one way to skin a cat - having a present but inoperative emissions system can often be countered with effective tuning.
