We provide a plug-and-play, tuned, ready to go MS43 engine controller to suit your specific needs. Please choose from the options avaialble when ordering, and contact us for any special requests.
NOTE: We do not recommend raising the rev limit above 6500 on vehicles without an oil pump solution.
This ECU is also unlocked/tuned so you can :
