Exclamation Help! Jb4 new - 05-21-2017, 10:50 AM

Hi,
I bought a new JB4 like a month ago. In the beginning I get a random safe-mode errors. I download the motor (n54) e92 repair all high pressure pump , water pump,thermostat, oxygen sensors, injectors, turbos, seals, etc... like $5,000. If i use the car without the jb4 the car work fine and great. When i put the jb5 I start to get errors inclusive if the jb4 is on map 0 erase the codes automatic. I flash the latest firmware and i cant resolve the problem. Every 5 min i get the safe mode message and jb4 automatic clean it, and in some minutes i get the same error and get safe mode drive.
Any one can help me!!

You need to attach a log in .CSV format. This log contains information about your jb4 configuration and is needed to adress your problem.

2F0C is an air intake temp fault.. Log might shed more light on it. Does JB4 have anti-lag kit installed?

sorry to bump a old thread but i'm currently running my jb4 with anti lag installed i'm intermittently getting a 2F0C code. with the half engine light. I have not had a chance to re flash my car with a backend flash so currently running without. Is this likely my issue or am i looking at a fault tmap ?

The BEF is required for anti-lag.

I just installed my jb4 with anti lag chip but not turned on in settings. Is it safe to say without a BEF the 2F0C will keep coming up sporadically?

I don't recall the code that it will generate but yes, you need the BEF installed.
