CARB Legal ECU Tuning

VenomNinetail · 03-31-2022, 11:30 AM

Hi, Just wondering if my Fellow Z brethren could help me out with something?

I live in Cali, and want to Run an ECUtek kit, but i couldn't find a carb exemption order for it.

Are there any Carb Legal ECU kits, and any engine management kits, that bypass the ECU, so I don't fail OBD-II inspection.

I'm also thinking of adding a map for flexfuel. in addition to the standard 91 octane, and vaslet modes.

Contact Eugene Turkov at enthusiast auto care. He'll have CARB legal tunes soon.

Same question about EcuTek. Has anyone in California tried to pass smog this year with an EcuTek tune, and if so, what were the results?

If not, what did you do? Does their support give you some way to go back to the stock ROM?

Can’t say 100% but your probably going to have to flash back to oem to pass smog. I didn’t bother risking it and just flashed back for smog and then flashed back to tuned after. I have a flex fuel map as well and depending how your setup (not boosted) you may not have issues. Msg if you want to know more.

Uprev claims to have a CARB-approved tune at https://www.uprev.com/secure/uprev-carb-cal.html

“This tune is for people who have a license on their vehicle already and are not able to pass their states inspections. This is a performance tune so it is not stock settings. They meet all criteria for 100% C.A.R.B. approval. This will be permanently written over your current tune so that your vehicle is in compliance.”
