I'm wanting to know if anyone was able to upload a different OSID tune file, successfully, to a 2015 Mustang GT using HP Tuners 2.25 beta.
Can this be done by taking someone else's stock file, but different OSID file and changing the VIN on the file somehow? Anything else to look out for?
Any How-To's that would point out how to do this with the new 2015 Mustang GT ECU?
I have a base 2015 Mustang GT with MT82.
OSID: FPGM0KE
Any recommendations on what OSID to use?
I'm having an issue with some weird idle routines when the car is cold/cool, and the car also runs very inconsistent (almost like its on/off the throttle by itself, or majorly inconsistent torque management) when not up to full operating temperature.
The service department said everything is within spec and they didn't discover any mechanical issues that would cause this.
Back in the day, on the GM side of tuning, I discovered that different OSIDs may have had the same parameters, but the routine's that handled them were a little different, which would cause the car to run/act different even though the parameters were the same from file to file.
