Hi there,

Firstly I am new here, and sorry if this goes against forum guidelines. More than happy for someone to link me if this has been covered. I did do a search and couldn't come up with anything.

Im trying to wire in a Motec C127 display and in KManager am unable to select any of the drop down items from either Digital or CAN outputs?

Any help is greatly appreciated as this is the last piece to the puzzle.

Thanking you

You need to open a calibration.

and as soon as you got it open, turn on the appropriate CAN in the drop down (data speed etc) and my frames came flooding out.
Now need to see if there is a doc for what each of those frame IDs are. Not sure if they are honda or hondata specific

silly me, its all here

now just need to get excel to pick apart the data and turn it into something useful

and when you get the frames capturing can you look at the IGN part of the 663 frame. Its 16 bits (the second two pairs of hex) and its signed but the documentation doesn't say how many bits for the sign and how many for the ignition data.
My quick capture was only 00 00 or FF FF and I can't make a reasonable number come out of 0, 16, 255, 4095 or 65535 depending on how many bits for the +/- sign.
Or just post a few of the 663 frames and I'll work it out from yours.

Ah ok so it assumes the first bit is a negative decimal number. But tagging a value as signed or unsigned is like having another bit of info. And the max negative side will always be 1 value larger in magnitude.
Thanks Mr Hondata!
