    convrting to 2 bar no OS conversion for this setup?

    I put a 1998 7.4 liter vortec into an F-body,I have added a turbo and bought a 2 bar map sensor looking to delete MAF. How do I convert this OS over to speed desnity ? I seen this option in OS section on other ECU's but is it not avalible for this setup?

    Custom o/s are not available on the vortec pcm. To take advantage of one you would have to rewire and switch to an 0411 style computer.

    so can I just add more paremeters to the MAP table to make it work or is there no way to expand it with HP tuners?

    I would not use that controller for that application.
