Default Need help after single turbo install - 06-17-2020, 06:52 AM

Hi Every fellow n54 enthusiast,

Recently I installed a speedtech single turbo kit on my n54. I am running a helix overdrive kit,precision coils , bucketless walboro 450/525 with a hob switch. I am using a jb4 with a mhd bef controlled with a mac solenoid. I flashed the newest St firmware and bef. I installed a new tmap and keep getting 2abc/3100 and a half engine light. I changed the sensor settings from 0 to 1 on jb4. The car runs horrible and bogs out. I switched it back to 0 and its drivable. I re pined and in not running the harness. I was abel to get one log

Do you have the n20 option selected via MHD ?

If yes- uncheck & reflash

Set JB4 to 1
