Thread: MSD EFI LS and Racepak

    Default MSD EFI LS and Racepak

    Has racepak come out with a cable to connect the atomic efi on the ls motor. I have an IQ3 dash and a 2002 lq4 motor almost three years ago both mad and racepak said this cable was almost ready for sale. Does anyone know if it is and what the part number is. I know there is a cable for the throttle body from msd to racepak dash. Will this cable work for the efi on a ls motor.

    no sir, that was part of the brain wave that got discontinued about two years ago.

    with that being said are you aware of how someone would go about getting there very expensive dash to read what is going on with the engine. It is a shame that this system was cancelled especially after I purchased this combination based on what MSD claimed was a well paired system. Any help or part numbers would be helpful.

    unfortunately, there dash would require the use of the racepak sensors and hard ware .

    after talking with both racepak support and msd support this is possible. No single company makes a specific cable but they each offer half of whats needed. You can purchase an extension cable for the hand held unit from msd and you can purchase a ls atomic cable from racepak. Cutting the ends off the racepak cable and attaching it to the handheld extension cable will enable your dash to read everything the atomic is monitoring. The only down side is you cannot use the handheld and the racepak dash at the same time. Racepak offers detailed instructions for the wiring and msd was helpful with providing the cable.
