  1. [need help] downgrading GPEC5 ECM/Harness hardware to GPEC2a?

    I have zero understanding of those systems, so apologies. What the guy from Prodigy added to the discussion is the body harness, so I'm asking if the engine wiring harness is connected to the body harness (and if so, do the controllers part of the body harness)? again, sorry for my ELI5 level...
  2. GPEC5 limitation, More power, How to?

    hmm, that's good to know; my goal is to gain more power in the low range than in the upper, so maybe a larger throttle body and ported manifolds are not the way to go...

    I'm from IL the country, not the state, stuff here is extremely expensive, all imported cars and motorcycles need to pay tax between 114% and up to 129% depending on engine displacement and pollution... fun.
  9. [need help] downgrading GPEC5 ECM/Harness hardware to GPEC2a?

    Thanks much for the detailed reply, sounds like a task for a hardware reverse engineer... in any case, from your input I get this is a brick wall.

    @Escape.idiocrac, thank you for replying! the thought had crossed my mind, and I've looked for what in the market, I have two issues with it. First, there are not so many gladiators on my side of the woods. The second, this is a brand new vehicle, less than a 1K mile (it costs $135K here, and...
