Hello all!
I have a 2004 Dodge Ram 2500 4x4 5.7L with 61k miles that I got a few months ago.
I've recently added a Superchips 3842 Flashpaq Tuner and did a "Quick tune" to the 87 Octane mode and i am getting great performance from it. However, since installing the tuner my cruise control shuts off once I reach 47mph, and will not turn back on when I push the button until I have slowed down to lower than 47mph. The cruise control worked perfect before installing the tuner. So, I reset the truck to stock settings using the same tuner and the trucks performance has went back to stock, but my cruise control still shuts off at 47mph.
After reading online i decided to try to adjust the tire size through the tuners advanced tuning mode. I measured my tires and set the tuner to the correct size but didn't do any other changes in the tuner, all stock settings except tire size. No change, cruise still shuts off at 47mph.
Next I set the tire size about 1.5 inches bigger than my tires actually are just to see if there was any change, and there was. Now the cruise control works until i reach 66mph and then shuts off, and my speedometer is also now about 3mph faster than what my stereos GPS says i'm going.
So yesterday i reset the truck back to stock using the tuner, then I took my truck to the local Dodge dealer and asked them to flash the pcm to factory settings. Upon hooking it up to their computers, they said everything looked stock, including gear ratio/tire size, and they didn't feel comfortable re flashing the trucks computer because it could brick the computer and then i'd have to buy a new one. I was very confused on how he could brick it by re flashing the stock flash onto it, and he couldn't answer me as to how that could possibly happen, he said "that's just what my tech told me". So sadly I left with no solution and nothing else to try.
So, now that I am out of things to try I am really hoping someone here can give me some ideas on how to fix the cruise control. I'm going out of state for Thanksgiving and it would be great if I could set the cruise and have one less thing to worry about.
Any help would be greatly appreciated!! Thank you very much!
