I just got a 6 pos ts chip with their canned tunes on it just to try out before
i get custom tunes for future mods.
my truck is a 99 f350 4x4 dually manual trans.
build date 05/99 / pcm code DAC2
ts chip says default code AWA3 on the card that came with
my problem is when the chip is plugged in it starts fine in any position
but a few second after i drive the check engine light comes on
the truck still drives fine , this light comes on while going slow and stays on
not under boost , it is not flashing, just on solid. cant be an overboost condition as when i turn the truck off and restart the light is off.
A few seconds after i start to drive even very gently as to not generate boost it will come on solid.
is it a bad burn ? wrong year ? any help is much appreciated
i searched and could not find any direct answers.
thanks
Dustin
