Thanks for all the advice So it seems the main difference between the FIM ECU & PC is the ignition adjustment & the FIM ones come with better maps so I'm told by Neil at sigma as they're set up on the dyno & tested on the bike Does anyone know what ignition/timing adjustment involves and the benefit/effect of ignition/timing adjustment other than more power (which is a good thing!!) & do you need new maps if you change the gearing Thanks |
