Did HP Tuners get your EPATS issue fixed?
We are still working on the issue at this time. I spoke with Eric at the beginning of the week on the issue, and he is going to UPS some of HP's equipment next week out to me, so that he can remote tune the ECU via my laptop and their interface in an attempt to delete the EPATS.
Aside from road testing the car (driveshaft shipped yesterday) my bypass solution is solid as well, of course, it should be as it retains the factory equipment and PATS system.
Now that I've proven it out, here's the details:
My system simply incorporates using the stock BCM, which is the interior fuse block of the truck the motor/trans were removed from, as well as the PATS transponder antenna and 1 key from the parted out pickup. The Fuse block is small, so I simply pined out the fuse block which was 7, 18 gauge wires including the PATS antenna, power and grounds. Secured the key to the antenna and the antenna to the BCM, then located them behind some paneling in the trunk of the car.
This serves two purposes. The second being, there is no external neutral safety switch or backup lamp switch on the 6r80 trans, therefore you have no reverse lights without the BCM being involved. So now, I have the reverse lamp output hookup on the BCM to activate the reverse lights in the Marauder, keeping everything working on the car in totality.
For this to work, unless you have dealer level scan tools to reset the PATS, you need to have the PCM/BCM/PATS Antenna/Key from the same donor vehicle.
Eric @ HPT still wants to use the car for R&D at this time for their EPATS disable, so we're proceeding with that next week, it will allow me to remove the key/antenna from my BCM, but i'm still retaining the BCM at this time due to my backup lamps being necessary.
I will keep you posted on the EPATS bypass as we progress. The way it's looking, the car should be on the road by next weekend!
