PPEI Tune selector

[Shawn Thomas]

so I was looking for a tune on ppei today for a different engine and stumbled back over to the ecodiesel tunes and they now make an option that you can select between all the tunes they offer, for an extra 150$ (100 for the other tunes, 50 for the selector switch). I am mainly just throwing this out there for those who might be interested and didn’t know about it, and also, if someone does decide to go that route, let us know about it!!

How does that switch work? Plugs into the OBD Port or?

That I’m not sure about. I was actually wondering that myself. I’ll look more into it tonight, but this seems to be the closest anyone’s gotten to something other than a single allowed tune which is interesting

PPEI said the tune is switchable on the fly, and the selector is wired into the ECM and ran to the cab I presume. Below are the install instructions they emailed me

Figured it was something like that.. did that on my old Duramax. A very tedious process!
