Hey can you tune a SDI system, we all have learn't to tune carbs
but are we going to be able to tune the SDI system h, have Ski-Doo left the electronics open ??

If they haven't how will we hot up the sleds ?.

Can they not play with the programming of the MPEM on the MXZx 440 sleds? When I bought my 2001 MXZ 600, to make an extra DESS cord for me, the mechanic had a scan tool that he hooked up to the MPEM & had a DESS cord plugged into it too. He pushed a couple of buttons & I had my cord.

Glenn: Talk to the mechanics @ your dealer, they should be able to tell you.
