Sorry to hear you are having trouble! A few questions...Ok so updated my xrt pro last week to the latest tunes which are very nice, but now running the hot damn tunes my cruise doesnt work. Anyone else having issues? I talked to H&S yesterday and they say no, but I see on their forums another person has same prob.
Thanks for the info. We haven't had a problem with this before, we will gladly get your situation forwarded to our Ford Engineer for consideration! Another question that may help us, is the check engine light on? If so, what codes?Thanks for responding H&S I talked to someone on the phone this morning about the issues. Have not changed tire size or speed limiter. Loaded tunes on Thurs drove about five hundred miles over the weekend. Actually pulled over and restarted truck a bunch of times as this has helped in the past with new tunes so I would say at least 30 key cycles. Tried reloading tune last night drove approx 80 miles 6 cycles no different. Loaded default tunes when I got home, but have not been able to test.
Definitely is not fun. You can return to stock without putting the DPF back on and still get one start to test if the code comes on. In the event that it does, then it would be necessary to find a mod friendly dealer or put the exhaust back on.Yes I must have miss typed I was going off memory. Very frustrating I guess I should have left well enough alone as It's a real pain returning to stock to take to dealer.
Correct, you will get all sorts of emissions codes. Drive it for a few miles anyway and then check to see if one of the codes you get is the Brake Switch. As we said, you will get one start once returned to stock and the sensors are unplugged. After that one start, the truck will not crank and you will either need to clear codes to get one more start, or re-install DPF removed tuning to get multiple.I guess I'm not following you if I return to stock and start engine with no sensors hooked up I am going to get all sorts of codes and engine lights. Brake lights function normal although I think it's somthing to do with the update because the one you released just prior to I had no problems with, but it did rattle so I updated again when you released that version and that's when the problem started. Oh well I'll figure it out
Couch- I think I may know what your problem is. There is a switch on the fire wall down by the break peddle that for some reason goes bad with tuning. I have come accross this a few times on the threads. It will throw a code if its bad I believe it only a $15 part from the dealer. I run spartan and have not had any troubles yet. But you might want to try going through their 6.4 forum I believe that's where I saw a few guys talking about it. Never hurts to check it out.
Great info guys! Definitely something for the OP to check. Easier than putting the DPF back on that's for sure.Im also running a Spartan and mine started doing the same thing, no cruise. I would have to pull over and turn the key off then back on, but over time that would not work either. It ended up being the switch thats on the brake mastercylider. That switch actually tells the crusie your on the brake thus not engaging the cruise function. Its the very first switch from the front of the truck that located on the bottom of the mastercylinder. Hope this helps.
