So, I have a full Akrapovic system, I didn't make any changes on Exup.Between 7000 and 8500 rpm, the pointer of the rpm meter is trembling during constant acceleration. :error Could this electronic box fix the problem, or should I do anything else?

I'm not certain but I've heard that you need to fool the computer into thinking that the EXUP is there.

thats correct. you do have to fool it. does your tach dance all the time while youre riding? by dancing i mean going up to 8 grand then down then back up to 8 every 3 seconds.

It isn't dancing.Do this only between 7000 and 8500 rpm, at other rpm rate it works perfectly. How can I fool the computer?
