I have a 2003 7.3, that I am in the process of installing stage 2 injectors from PIS, and a GearHead Hydra chip. GearHead tells me there is no way to run the Hydra without unplugging the PATS module, under the dash.
Here is my question. Is this even possible with out ending up with a disabled Excursion, and if so, what will I loose by unplugging it?
If this is possible, where is the PATS module? I was told to just unplug the big green connector going into it.
I just plugged mine in and ran with it. I did download the software, but I have not changed anything on the chip since they sent it to me. My theft light blinks rapidly for about 2 mins each time I start it. Then it just goes away...
This is the reason I purchased the DP F6, it works with PATS. My dash lights operates as designed. I did pull my DP, but PATS works correctly with the chip/tune.
I would like to try the Hydra/gearhead, however I don't want to rear into my dash to disable modules of the Excursion.
