Hey all -
I'm currently knee-deep in a project truck...a 1990 Suburban 2500 4x4 that is getting a Vortec 350 transplant. This is also including the Vortec manifold/fuel injection being operated by the 0411 PCM sourced from the '02 Express van.
Seeings how I am trying to get a *slight* increase of fuel mileage out of a 6,000 pound beast, I'd like to implement a few things. Biggest change I'd like to do is adding electric fans and have the PCM control them. Is it possible to turn this feature on through the tuner, or will a custom code need to be done?
Thanks, Brad
