I was looking at my local Craigslist for some parts for my 00'' 7700 that I just picked up. I came across a Hypertech tuner that someone had up for 100obo. The model is 42003 listed for 04-09 5.4 expedition/navigator. Would this work with my truck or no? Thanks in advance.

 

Can't tell if a troll or not. But no. Wrong model and vehicle.

 

No trolling here. I was reading that some people updated the firmware in models that were not specifically for their truck and they got it to work. Wasnt sure if anyone had tried to do that on here and had any success.

 

Haven't heard of it. Or anyone trying it.

 

I doubt it will work. The newer engines are different physically. They have 3 valves per cylinder while ours have 2. It's a totally different physical configuration

 

Thanks for the feedback, I figured it was worth asking.
