I think this would be a tremendous help in trouble shooting our finicky motors.
Don't really think any of the current tunes would be capable of doing this. OP, look into a Pro EFI ECU -- Undercover Performance are tuning on that ECU specifically for the N54. Strong possibility that the EFI would be able to monitor/store data like the HPF AEM unit.
