Problems with calibrating MMP

Got my MMP (running the original V1.22 software that it came with).


When I tried to calibrate it (turning the switch on while holding full throttle etc...) it registered forward fine but it didn't register brake/reverse ( and of course I didn't get to the neutral calibration part).

I'm running 2 MMs and one MMM in other cars with the same radio gear (Spektrum DX3R) and never had problems calibrating.

I tried to reverse the throttle channel and different throttle/brake end points but it didn't help.

Any ideas how to calibrate?

BTW - I tried running the car without calibrating the MMP and everything seems to be acting normally, the MMP isn't dead or anything, just won't calibrate.

make sure that the brake EPA is at 125

I tried EPAs of 100%, 120% and 150% and none worked.

I know that spek. dx2/3s have a "secondary" EPA on the grip that can affect the calibration...

I just verified the the EPA on the grip is set to max.
I also tried setting the EPA to 125%.
Still registering forward but not brake/reverse.

I had a similar problem with one of my MMPros. I tried a few things and can't remember which worked, but I fiddled with the throttle trim and also reflashed the firmware.

Brian,
did you reflash to the same version or to a newer (beta) version?

Actually, I flashed to an older version, and then again to the current version.

Ok, problem resolved.
I tested several firmware versions and the problem occurs only in versions 1.22 and 1.23.
Versions 1.21 and 1.24 calibrate without any problems.

good to know. I hope to see my MMP early this week.

I had the same issue, updating to the latest firmware seemed to fix it
