These LS1 ECU brackets were developed to make the life of anyone trying to mount one of the ECU's much easier. We laser cut and press brake these brackets from .090 steel for low cost and repeatable precision. Builders have mounted these ECU brackets under the dash and to the rollcage in a race car. The have been installed in delivery trucks and ski boats to some very high end hot rods. They can be mounted wherever is easiest for you.
