Homebrew V3(ish); whats the latest map I can run?

M3to335 · 07-27-2008, 05:05 PM

From what I understand vs what I have, the PnP V3 has an additional harness for controling fuel trim as well as a relay so the unit isnt sucking power all the time. I have a homebrew v3-ish with iat and map switching enabled from in the car. I said screw it to hooking up the traction nanny, so right now I am running the 5-22 map.

Are there any later maps that would work with this setup? Im not opposed to going the extra mile and mocking up the rest of the wiring if its at all worth it. Honestly, its running rock solid right now, so I dont even know if changing it up is worth it or not.

Oh one other question......I havent done this, but has anyone switched maps while flooring it? Is that a no-no?

You have the last non-fuel controlled map so that is it. And yes, you can switch maps under load.
