tps problem

A forum for discussing applications and implementations of the MegaShift transmission controller code for the GPIO from B&G. This can control up to 8-speeds and 6 shift solenoids (plus a 16x9 table for controlling a PWM line pressure valve). It has manual and fully automatic modes (16x9 load x speed table), with under and over rev-limit protection, and full data logging of all inputs and outputs (among many other abilities). A TransStim to test your completed board is also available.

I believe you contacted us by email; I was able to get the same error message, as shown:

However, it's difficult for me to match forum posts to emails, so I do not have a copy of the tune. Can you please post that?

I had exactly the same issue setting up my tps on my 91 diablo. I did point this out to John.

This problem is still in the code. Anyone around who can fix it? I’m guessing it’s something with the INI?...

So originally I was looking through the source code trying to figure out how to get this function to work; it never dawned on my till to today to think, WHY doesn't this function work. The simple answer, IT DOESNT NEED TO. We are so used to using the TPS calibration function because that is what was used in most MS projects. This controller is coded to use either CAN or local TPS... or MAP signal for load. It is not setup to use both separate local Map and local TPS (for whatever reason, and I might look into trying to incorporate that for myself in the future).

ANYWAYS. Long story short. The tool you need to be looking for to adjust your tps OR map min and max values is below TPS calibration and it is called "non-Canbus Load Calibration".
