As far as I can remember, the piggyback, well, the eManage anyway.. Just fudges numbers for air, fuel, and spark. Defo no timing.
Why go piggyback? Bcoz at least if it *poo*s itself, and needs fixing or retuning,... You can just switch it off, and run the factory ecu and tune n keep driving.
With a reflash or a stand-alone, you car is a paperweight until you get it fixed.
Much better for those on a budget, and that have only one vehicle.
