DME program mismatch caused the issues. Ignore the "warm up" lights on the tach in the running video at the end. The oil level/temp sensor is not working correctly.
I don't know which specific maps had the issue or if it was the file versions having a mismatch. For example, 1601 base file versus 1701. I know the EWS deleted file with the tune on it was created from a 1701 base file. I determined the issue by matching the tune file back to the DME it originated from. This way I knew the base files would match. Since then, the only actual help I got was from a friend to get a stock/factory full 512kb file loaded onto the DME I intend to keep in the car moving forward. Now I have a known good 1701 factory file from which to have a custom dyno tune worked up. That likely won't be until the fall. I'm still waiting on some specialty parts. For now I still have the tuned DME from my other M5 bolted into this car.
Do you think it is legal to make carbon fiber of all car parts, even the car chassis?❤
Who was able to diagnose this base map vs other throttle map for you?
