Default Fault code with BEF/JB4 - 11-07-2020, 11:01 PM

I reinstalled everything as usual and then used MHD to add the BEF. I drove around town and then took a trip to a friends house an 1.5 hours away. The car ran like a beast. Parked the car for a few hours and when it was time to leave the car would start, sputter and then die. I was able to get it in the driveway at the friends house. Something told me the JB4 was the culprit. I took out the JB4 and the car started like nothing happened. I did get codes 2c58, 2c6f and 2c70.

Something with the TMAP connection/boost sensor. Perhaps a loose OBDII connection?

I assume after removing the JB4 the BEF is still present? If it is, do I need to flash my MHD stage 2+ bin from before until I have more time to work through my issue?

You can run on the BEF only while sorting out whatever your problem is, or flash to Stage0 stock tuning if that's easier. I wouldn't waste money on another flash map.

How does your BEF compare to the MHD stage 2+ that I purchased months back?
