  4. Hi,

    Im looking for some info on the GM 25008302 MAF. I am trying to use it in my research project, without an ECU and on a stationary engine. I was wondering if you know what the supply voltage, and current it requires, the signal type, and how I would convert that signal into mass airflow. Finally, Im looking for the 3 pin pigtail, if you know what part number it is, I might be able to find one.

    I know this is a lot of information you might not have, but if you have any, we’d like to hear!


  5. Hi,
    Just wondering, will it work if I hook up AFC neo unit to a haltech sprint500.
    So that I can have last minute touch up for NY engine.

    • Hi Din, thanks for reading!

      yes the AFC NEO will work great with your Haltech, are you using speed density or a MAP driven system? It’s flexible, easy to use and would be great for quick touch ups to your tune as you need them.

      Thanks for commenting, let us know how your project turns out!

  6. Y’all know if anything from a 96 Acura 2.5 Tl can be used or swapped into a 94 Honda civic..? The Acura is a straight 5 which I never knew existed before seeing this car

    • Hi Donnie, sorry but that’s definitely a rare engine that’s not normally a Honda swap. There’s not much information on this swap but that doesn’t mean you can’t be the first! Sounds like an awesome project, let us know how it turns out!
