I recently swapped to a 3.5 bar map sensor and flashed the car with the n20 option MHD only. After driving for a bit the vehicle runs rough and im getting a 2D2E THROTTLE ANGLE FAULT. i bought the adapter harness from bms but it had a little tab that i had to cut off on the harness side. Any idea what can it be?

Have you try to reset throttle adaption, also double check and make sure everything is plugged in and the sensor is installed all the way

Sounds like you got a counterfeit sensor as you shouldn't have to cut any tab off the harness, its straight plug and play with the option ticked in MHD.

Switch back to original sensor, revert the harness to factory position, untick the box in mhd and see if the problem goes away
The sensor i dont believe so i swapped it with another 3.5bar sensor and it does the same thing. The adapter i brought straight from burger motor sport. I had no other choice but to stick with the stock one

If you interested shoot me an email [email protected] . Would like to send you a test map to run. I had couple of customers on my end that bought the BMS N20 kit and when they used the MHD 3.5bar support option they got those same codes. When I integrated N20 3.5bar calibration into the map itself they didnt get those codes anymore.

Pretty sure that mapping option is for jb4 people
When you're running JB4 with 3.5 bar, JB4 handles the conversion with N20=1, flash needs to remain stock 2.5 bar or JB4 will rescale on top of it already being converted in the flash.

Sounds like BQ is saying there may be an intermittent issue with the flash time values writing or they may be writing different values than he uses.

I have the same problem with two different TMAP sensors. I have tried to use the checkbox on MHD with the same error.
