I've tried race gas without any changes, and I run nothing but 93 octane. Terry from BMS said the only thing that would fix the problem is the backend flash... which I think is ridiculous... I spent ~$500 on the JB4 expecting it to work nicely... it doesn't, and now I have to spend another ~$150+/- to make it work properly... I should have just purchased the COBB AP at this point...

The tablet has OTG support, it came with an OTG cable, and the OTG cable works when I hook it up to the JB4's USB cable in the car...

I'll buy the cable from or whatever and see if that works... if not then I guess I'll be selling all this crap and getting a COBB tuner....
Don't buy a Cobb. Use an existing Android device or buy a $50 tablet from Amazon and use MHD rather than Cobb. Way cheaper and better supported.
