2017 mustang GT 6MT PP BLACK
HI guys~

this is my first post here~

I really don't know i should post it on Mustang S550 General Forums or Shelby GT350 Mustang Forums, I am facing a cross breed issue...


I have a 2017 GT PP

Two weeks ago, I swapped a tr3160 to my car, it run fine and smoothly, then i noticed a strange phenomenon.



if i press the clutch pedal and release the gas at the same time, my engine automaticly revs 1500RPM higher and keep the RPM like 1 second, then drop to idle RPM,

if i release the gas for like 1 second before press the clutch pedal, the engine will not rev higher, just return to idle RPM.

my friend said it is the rev match... but could a 15-17 GT has the features of gt350?

I have no clue how that happened, but it happens every day now...I really want it disabled.... but I can't find any setting in the gauge screen....



does anyone know how to disable it? using forscan?



what happened at that day

1, I swapped a gt350 guage to my car.

2. i found the mileage is incorrect, so i swapped my gt gauge back to my car.

3. I pulled the MT82 off my car

4. installed the tr-3160, two mt82 pigtails were plugged in

5. drive, the speedometor works correctly.



I personally suspect that

there maybe are different microchips in the speed sensor in MT82 and tr3160, once i plugged the pigtail to the tr3160, it enabled some features in BCM.

I am planning swap a MT82 speed sensor to tr3160, i ordered a new MT82 speed sensor, it is on it's way.
