there is this adjustable tuning box that i bought from germany a while back. At the current setting, while slowing down with the clutch not pressed and the gear in neutral, the engine's rhythm changes vastly, going from the usual tah-tiki-tah-tiki-tah-tiki to a highly pronounced TAR-TAR-TAR-TAR (sorry for the sound effects
) . This happens while only slowing down until I stop, once I stop the engine goes back to normal. There is no change in idle revs while this happens. And this doesn't happen if the clutch is pressed or stops when i press the clutch pedal. The tuning box is clearly not at its max setting as I don't have any smoke. Engine operation without the box is completely healthy. Since I had these symptoms I removed the tuning box, but I would like to know if there is something wrong with my engine. A remap could be in the near future, and I would like to foresee any problems such a serious power increase might bring along. please help me diagnose this guys
thanks a dozen
