LS3 Engine

[highflyer]

Could somebody let me know what ECU they are using on their LS3 motors please, mine has the GM one, but have since found out its very difficult to find anybody who will touch it so looking to change it in case of any future issues thank you

If it’s a standard engine then the GM ecu should be fine, however if your looking to change heads cams ect then most of the aftermarket ECUs should work fine, it all comes down to what you want it to do and the features needed. I’m running megasquirt MS3 pro ultimate, it’s got all the features and more that I need, it’s all diy with this system, maybe approach a local rolling road operator and ask which system he would recommend based on your needs and can map.
Good luck
