Title: Engine swap. Can I use 900 PC map to compensate the 620 ECU? Post by: Goggles Pizano on July 11, 2008, 03:12:14 PM As title says. Can I just download a 900 map from power commander and plug it in to the 620 ECU to make the 900 engine run right?
If not anyone got a map or know of a site to download one? Thanks Title: Re: Engine swap. Can I use 900 PC map to compensate the 620 ECU? Post by: clubhousemotorsports on July 11, 2008, 08:25:10 PM Yes and no
the power commander is just affecting your fuel. The 900 and 620 I am sure have different ignition timing as well. the power commander does not address this. you could try it and as long as you are not having any detonation at wide open throttle you probably will be fine with just adjusting the fuel. I just tried a set of ignition boxes that were for a 750 on my 853thingy and the bike hit a point around 8000rpm where it was not happy at all. went back to 900 timing and the bike pulled cleanly to 10,000 sorry no help with pc maps. anyone?

Post by: brad black on July 11, 2008, 09:19:38 PM a 900 map assumes you have a 900 ecu on a 900 motor. what you have is a 620 ecu on a 900 motor, so you'll need around 50% more fuel as a starting point. not sure how much spark advance a 620 has, but it may hurt power a bit if it has more than the 900. worth a try anyway.
