Is there anything i should check or need before buying second loom and ecu?
I spoke to dynojet last week who told me they should have a cure for 07/08 bikes by the end of the year, thats fine but by the time its had a custom downlod it,ll be over �400, i can buy a lot of fuel in russia for that.@40p lt.
I understand where you are coming from. Dyno jet like me thought we were close to a cure for the 07 XT's. They have also hit some hurdles & are still working on a cure, I am still in correspondence with Dyno Jet UK. We now have a new forum member from Dyno Jet USA on Board, I am sure he will introduce himself later. A power commander with a custom dyno fuel map will improve things, but it will not cure your problem of surging, the O2 sensor is still a problem for the 07/08 models in the closed loop circuit.

If you want to get rid of your surge once & for all, you will need a 04/06 wiring loom & a 01 ECU with a fuelling device. http://www.xt660.com/showthread.php?t=8478
