Hi everyone, I am sorry if I am not posting in the correct place, but this is my first post- I'll learn the ropes!!
I bought a 2002 Mustang GT back in August of 2012, and she ran and drove great. No mechanical/drivability issues whatsoever. It is a 5spd, and it shifted smooth, everything felt exactly like it should have. However, the only issue was: the speedometer was off by about 10mph. So I decided to pull the car out of the garage since it is officially Spring, took it for a spin; needless to say, it was awesome!
I then decided I would update the SCT SF3/X3 tuner with the newest updates and firmware- but first I returned the vehicle to stock, then proceeded to update the device. It updated successfully and still had the custom tunes from BAMA. I brought it out to the car and tried to load the 87 STREET tune, but I adjusted the tire size to 790 revs/mile because the car has 18" rims with 275/35/18 tires and I calculated it out to 787.9, and the tuner only increases by 5's so I figured that was the closest.
Instead, the idle RPMs are really low (500-600) and the car shuts off sometimes, even with the clutch all the way down. The speedometer is off (says 110mph when I'm going like 50). The RPMs don't drop after I shift up either. The RPMs don't dip like they are supposed to after a shift. The car just doesn't feel right at all, I really just want to bring it back to the tune I had before. I have tried returning the vehicle to stock with all tunes completely shut off, and the car still does the same thing and behaves the same way.
I am not sure what to do or how to go about it- all I know is that SCT Customer Service is very hard to get a hold of, even during their regular hours of operation.
I'm hoping that my new friends on here can give me some insight! I've even tried letting the car idle for 10 minutes, turning on the A/C and letting it idle for 5 minutes and repeating, but it doesn't smooth itself out.
The car is 11 years old now with 109k - so I don't think there's a warranty on the ECU :laughlitt
I appreciate any help or guidance, really, I do! Thanks in advance!
