when you order the ecu you tell on which bike you will plug it and they send you the proper wire(for Xt660 or raptor any any other injection bike) and you plug it straight away by removing the stock ecu and connencting the new one,and also you have to unplug the immobiliser wire under the fuel tank to work properly on xt660.The map is 3d you have to set all air-fuel-advance-ignition to work properly,i think there was a topic with the links

ok...can you find the links Steve.....very useful information for me...thank you.

Is it a Dynatek ignition for a Raptor 700?

Allmost plug an play... 3D ignition and fuel maps and a lot more

Not really that expensive and you get full control over fuel&ignition systems and there is quite good documentation available for megasquirt
...this is what i would use

heh... thats just a -little- bit complicated for me...
