Will COPs work with the OEM ecu?
 

As the title says; does anybody know whether COPS will work with the OEM ecu?

I searched but could not find the answer.

Also, if I wanted to take my car back to NA; what else besides the MAF would I have to consider?

Thanks

I dont know if they'd last but when I did emissions last year I ran them with the stock ecu for a couple days and they worked fine.

I have my COP setup running on the stock ECU (99 NB). Been running for over 2 years now.

Good to know.

Thanks to both.

Mike, we don't have to pass emissions down here.

this is good to know. what about on a na?

Yes, it will work fine. I drove over a year on one of my motors with Toyota COPs, NA na, without issue on stock ecu. Its "pnp"ish, just have to wire it in or make the pnp harness using a gutted ignitor, I had no need for the dwell reducer circuit at all.

Umm, time to start looking for cops. What year and model toyota should i look to get
