Default 7 Series with JB4 - Cannot Remove Engine Light? - 08-08-2020, 11:24 AM

It may be posted someone, but I can't find out how to keep the engine light off?

I have a 2013 750i with the JB4 just installed, I also have a cold air intake system with the Mass Air Flow Sensors disconnected. I can remove the codes for the Mass Air Flow sensors, but the engine lights stays on.....what am I doing wrong?

I am using the JB4 app with an iPhone.

Thanks,

Ron

Can't get rid of it. As long as the MAFs are disconnected, the light will be on. Autoclear has been removed from the JB4, so the light will always be on.

Well that sucks! I am told by Burger Motorsports my application must have the MAF's disconnect more max power....and this autoclear option was one of the reasons I purchased the JB4 over flash tuning.
