    Agree. I have done that too. Simple to check and fix.

          fatii: send the config to someone. The first thing i would check is the fueling map as it may be that there is not enough fuel when the throttle is pressed and therefore it stalls.

          then i could start thinking other things. When vems was fitted, did anyone check the timing marks with a strobe light? Have you changed the VR sensor cable as should be done? Have lamda and IAT sensor and TPS sensor been calibrated? etc etc etc
          I need your mail A80Avant

                  The sensor on the flywheel teeth is 0.5-1.25mm. The one that picks up on the small single pin is 0.45-1.25mm.

                            I had a look at the config and I must say that it must be a combination of things. The basic settings seem ok but the maps are decently horrible.

                            You need to upgrade the firmware to the at least stable 1.1.95 and make sure you use a strobe light to check the timing angle that it corresponds to vems. Then I have made some changes to the map but I have sent an email to find out some info for the engine specs before I continue.

                            Whoever decides to go vems they MUST get involved and not rely on a tuner who knows generic stuff. Whoever put values on this map either wasn't interested in the car or didn't know a lot of info. Please read about what you can do and we will try and help you as much as possible.

                            The crank sensor needs to be as close as possible without fouling the pins. If it still doesn't work then you need to weld a larger pin by copying the size and length of the original dual mass flywheel pin

                              I also got the config file and not by what is done there that the car will have that problem. If you look good is constantly trigger errors. Any problem with VR sensors.

                              The tables must be done correctly, but I repeat that what is there, must work properly and do not turn off the car as it appears in the video.

                                The only way to find out is to make sure the car has an ecu that is properly configured and doesn't have all those config validation errors. Only then you can say its the crank sensor
