  • Megasquirt and FI tuning question

    I was searching posts and one thread seemed to suggest that I could skip complicated tuning and buying the 500$ HPtuners programmer to tune my low-boost setup, if I bought a megasquirt? Is this true?

    I'd be using either 27 or 36# injectors, and wouldn't run more than around 7#'s of boost.

    You want to avoid complicated tuning by skipping HP Tuners and getting a Megasquirt system? I think you may have that a little bass ackwards. Megasquirt is all custom stuff, replacing much of the PCM's functions. Compare that with just editing a couple tables in HP Tuners.

      Yeah, I posted that before finally finding the main MS site, and reading that I'd have to basically rewire my ignition and fuel system.

      I think I'll pass.

        It is pretty complicated. Even though I run it and love it it would still be a better option for most to just go with hp tuners. At least for those that can use it. I still don't like the inability to tune for boost and have the MAP sensor actually see greater than atmospheric pressures. But I guess the MAF could compensate?

            I looked into the megasquirt too but I found out that no one has successfully gotten the megasquirt to work on a 3.8 motor yet.
