Thread: Commander 950-24S Specs

  1. #1

    Default Commander 950-24S Specs

    Looking at a Commander 950-24S for a '72 Cutlass 455, that I currently have running on a carb. It's a street car, just built the engine last year. I would say it's mild to moderate probably around 425 HP & 500 torque. I like the idea of the Commander, as I can use it with the GM HEI/Mallory CD Ignition that I have to control spark, and I will also be able to tune it. The kit I'm looking at comes with the narrowband O2 sensor, and on the back of it it says:

    Holley Pro Version 3.0

    200R514-1AV 0611

    012 '04

    I'm not sure what any of this means. Will the ECU work with the wideband O2, or do I need to send it away to Holley to have its firmware updated? Will I need anything else extra to make it tune easier?

    Thank you.

    Yes, software/firmware version 3.0 & higher is capable of running a WBO2 sensor.

    Try the "350_85.950" base map. You may have to "Cell Action" the entire Fuel Map for more fuel.

    You're welcome. I attached a zipped copy of my tuned Commander 950 TBI engine file (900 CFM, 75 PPH injectors, 22 psi, big block Ford) to post #4.
    It should be a much better starting point than any C950 base map. Of course, you'll have to change the Engine, Ignition & Oxygen Sensor Parameters.

    Can the Commander 950 be used to control timing using a GM 4-pin HEI? I see in Appendix 10 of the manual it only references the GM 7/8 pin HEI?

    That's because it has to be a computer controlled distributor for ECU timing control.

    So on that thread the guy was running a Pontiac (similar to Oldsmobile like me); I would need to track down a 7 or 8 pin distributor to be able to control the timing? It can't be wired to work with a 4 pin?

    Yes, you must use a computer controlled ignition module for ECU timing control. If your distributor has a mechanical (centrifugal) advance mechanism, it won't work. It has to be an OEM computer controlled module/distributor.
