Help finding a COS (Electronic Traction Control)

[L31Sleeper]

Hello L31Sleeper,

I realize it's a 408 - but the parts combination was not stated. Had assumed it was using the 5.3 L TB / injectors / and perhaps MAF. If so, those 5.3 L parameters will need to be used, and the displacement set to 408 CI.

You are welcome, by the way ... hopefully it works out.

Taz

You are right more info would help. umm...slow hoe

Sorry guys. My work computer won't let me on the forum so I am using my phone. It's a 2002 Tahoe 408ci, 60# injectors, TVS2300, LS2 DBW TB (i have an adapter harness), want to go to 2 bar map if possible. What else do you guys need

And I have an 80E now. The Tahoe was DBW from the factory. Runs on a MAF tune right now.
The tune attached is with a 6L, 42# injectors, oem 87mm DBW TB, M112 blower at 8psi.

You are going to have to switch to a cable throttle or get a corvette TAC and Throttle pedal.

The PCM / TAC / TB must all be mutually compatible - either all truck (in this case 2002 only) or all Corvette. Generally almost any APP (throttle pedal) may be compatible.

The DBC swap will probably be the most straight forward approach.

Is the limiting factor the boost level? I mean if I can run 8psi now can't I adjust the current OS to run the 408 with maybe 6psi? (maxing the MAF and fueling dependant)

In short NO, once you go above 0 the PCM doesn't know what is happening.
