Using the same pinout for the A & B connectors giving seamless upgrading from our other ECUs, the Thunder has two additional connectors (C & D) for increased capacity. This is the ECU for your high end applications requiring maximum performance, flexibility and tuning control, with the same sleek profile of our other “black” G4+ ECUs

Requires "A" & "B" looms and, if needed, C & D connector kits.
