TCU failure. Need help
I have a failure in my Rotax 914
As soon as it reaches about 4,500 RPMs, it starts sputtering.
Removing the airbox from the carbs, the engine will perform flawlessly as a normally aspirated engine, but with the airbox connected, the engine won't rev more than 4,500 rpm.
So I think something's wrong wit the TCU or one of its peripherals.
How can I use the Communication Program to diagnose and find the problem?
Thanks in advance por any help or comment.
