    V6 ecotec 3800. Tuning ls1 ecu

    Hi guys,
    I have heard of people using hp tuners to tune ecotec 3.8 v6. Can anyone give me any ideas how this is done.
    Do I change platform?
    Firing order?
    Any heads up would be greatly appreciated. I relies looms wil have to modified and I have been told to use an ls1 2003 operating system.

    Once again guys thanks in advance.

    I have been looking at this too.
    I think I have worked out the crank and cam signals through the DFI module to the pcm.
    dont know what to do with the est bypass wire ?
    I think we have to select low resolution in system options.
    If anyone has worked it out please share this info with us.
