Why does MPH stop at 127?

[mikel]

I recall something about there being 2 speed pids, a high speed and low speed, and one will stop at 127 as it is the max value hard coded for that PID?

it could be worth a shot on DV.

problem is, trying tio get the tool to 'cache' all the PIDs for your vehicle would hog up tons of memory, and there is no way to just do it on the PC, since it needs to see the PCM to know what PIDs to offer..

well, the trinity does not store anything but the default pids you can select from in the list.
If its not in the list, it takes some work to get it into the default list for Trinity.

I mentioned this to Johan and he seemed to be pretty sure that the correct hi res speed PID should be there....?
