We just brought home a 2001 v10 this past Saturday. I have doing a few repairs etc. While I was installing new headlight lenses I saw this small, obviously not stock, dial.
The wires went into the air intake and at first I thought it was one of those gimmick “Electric Supercharger” things that are worthless. I went ahead and took air filter box and tube apart to inspect. No “Electric Supercharger”. I flipped the dial over and saw this
Googled it and evidently it is a super cheap “Chip” that is supposed to increase performance and mpg by adjusting the MAF reading to trick the vehicles ECU into thinking it is running lean or rich. What the heck? It amazes me what people will fall for sometimes. This could explain why my initial mileage seems to be pretty bad. I was expecting 12-14mpg for mostly hwy trips....looked like I was getting 11mpg.
Anyone see an issue with me removing this and just splicing the original wires back together?
Just remove it and reconnect everything, for the MAF Sensor, you might want to dab a little solder in there to make sure there isnt high resistance on the connection or you may get readings that are a little off, but yes, some jackass obviously believes anything they see on the internet. Its just a resistor in a shell, possibly a variable resistor by the looks of that one, but none the less. And you are best off ripping those things out before they cause problems.
unless you have 3.73s i wouldn’t expect much more than 11mpg though.
Okay. I currently have 3.73, but looking to change them in the future. This vehicle was specifically bought to tow our camper, so deeper gearing will help.
It’s official, I no longer have a chipped/tuned Excursion. At least the previous owner was nice enough to use weatherproof spade connectors. Made removal pretty easy.
When other people say they have a chip or a tune, it never involves one of those, its either an actual circuit board chip that plugs into the ECM, or else a handheld tuner that edits the ECM programming directly, in the case of a chip, there is no wiring, it just plugs into a factory port on the ECM, in the case of a tuner, it just plugs into the OBDii port, what you had, was a fake knockoff.

Definitely. When I saw it under the hood all I could do was just shake my head and chuckle. I have reached out to 5 Star Tuning and will be getting one of their tunes for the Excursion. It will be dragging our 30ft camper around, so the change in transmission shifting etc will help a lot.
i actually found the tune SCT provides themselves on the tuner to be quite respectable, definitely more umph, but still perfect drivability, its the Strategy tune on the device, if you get a handheld tuner from SCT, they also include their generic mild performance tune as well, and it has a lot of configurable options in it, i get reasonable gas mileage on it as well. Been dragging my heels on getting 5 star to write a tune for it.

do it! i finally did it this past spring/early summer and I run the performance tune with stock transmission pressures as I have a shift kit installed and their transmission shift pressures are just way too much for my rig and normal driving. my normal mpg increased by about 0.5mpg and it drives much nicer
