Getting a catless DP installed sometime this week. I was wondering if it is possible to clear the CEL with JB4? Or if there is any other ways to clear it? I would prefer not to go through the trouble and price of getting a full tune and unlocking the ECU as I have a '21.

Also other than JB4 are there any other piggy back tunes that can be used with the locked ECUs?

You can clear it but it’ll just come right back. Only way to keep the CEL off is through a real tune. Just go get a real tune IMO and ditch the JB4. That’s if your car is tunable.

You can clear the CEL but make sure you know what it is for before you clear it. If its for the catless DP it will eventually come back.

Yes you can use the JB4 to stack with an ECU tune. Gen 1 B58s have been doing that with MHD for forever. BMS offers free MHD maps as well. When your car can be unlocked and tuned id go with ecutekt though.
