    In search of a E78 wizard for an L96 engine out of a 2012 GMC sierra 3500 WT

    Hey yall,
    I need a guy that can actually explain what some of the values in the E78 ECU are meaning. Mostly in an effort to get the Speedometer working so I can do idle tuning. As a side note, I am running the dakota digital 8K inline pulse generator with the dakota digital signal amplifier with zero luck. Also always looking for more information on the fan set up for this particular ECU. Currently just have both electric fans locked on due to not having the ability or know how of what needs to happen to fix this issue. I am finding TONS of info for the E38 ecu, to the point I have considered swapping EVERYTHING over. But I would rather stick with my E78 if possible to avoid the headache, I just want things to work! lol

    Any help is appreciated!

    Thanks,
    Dan
