Pcm4less Ecm Complete With Tune


Recommended Posts

evidently it'll work as long as 03 or 04.

It will work for an 03, but the fuel gauge will read backwards, as I've already found out. 03 has return fuel lines & 04 doesn't & it messes with the gauge.

 

Just to let people know...

i dont have the electric fans. would it be an issue or would that part of the logic just go un-noticed?

 

 

it would go unnoticed.... the computer basically has a bunch of empty plugs, so bryan at pcm4 less programmed 1 of the empty slots to provide power for the fan relay at the set temp..... if you dont connect a wire to that port, it would never be noticed.

it doesnt provide power it grounds the circuit. you dont have to have fans to use the pcm in fact if you do use fans I would have it reprogrammed anyways for a better fan control tune for your climate.
