transmission temp calibration
transmission temp calibration
So the question is; Is the problem for sure a tuner studios issue? Should I inform Phil about this or could this be something else? Basically, every time I tried to calibrate GPIO trans temp over CAN it would change the engine coolant temp. Every single time, it never once worked correctly with any version of GPIO or MS3 firmware or different versions of TS. I had never tried calibrating when I was connected through serial to GPIO since I'm almost always doing GPIO stuff over CAN, but it hit me to try today while reloading firmware and now it works great.

Re: transmission temp calibration
I sent a message to Phil and they had mentioned some of the issues on why GPIO probably would not be able to calibrate over CAN pass-through. It occurred to me that maybe I was not clear that was how I was trying to calibrate it over CAN and then I wondered if I had missed any info in the documentation I had read about not being able to calibrate over CAN pass-through?

Re: transmission temp calibration
The CANbus pass-through *should* allow the thermistor table to be reflashed, but doesn't (for you or on my bench, at least). This could be because of the INI has some problems, the trans code has problems, ms3 has problems, or tunerstudio has problems doing this. I will look in to the INI and trans code aspects of this.
In the meantime, as a work-around you can connect directly to the GPIO board to calibrate the temp sensor (then you should be able to use the CANbus pass-through for setting parameters, loading an MSQ or datalogging).
