After trying a few maps my 06 990 kept running like crap, adjusted the TPS, idled fine, but kept missfiring sometimes from idle and often when coming from a full closed throttle and then accelerating harder.

I read in the 690 thread that having ignition on, kill switch on, engine off, slowly rotating the throttle from null to full, and then full to null again slowly, and then switching the ignition off, would reset the throttle position against the ECU.

Did that, and... got alot better, not perfect, but no more sputering and hesitation.

Anyone did this before? Never heard for the 990, but it made a difference.
