theres a how too on justcommodores.just disable auto error codes in the tune turn the idle screw in until it doesnt stall coming to a stop from a roll and wire the speedo sender direct to the dash via the dash loom plug by the ecu .and send it out the door LOL
If Its Got Gas Or Ass Count Me In.if it cant be fixed with a hammer you have an electrical problem
Thanks delcowizzid, found and read how to on the other site, i probably should have been clearer, the mechanical part is a breeze, the tune for me isn't, surely just disabling the error codes isn't all there is to it?
