Dear Mr Hondata,
could you please allow us to separate out data logging frequency for each metric? Don't want to use the logging memory up too quickly but logging a temperature might need 1Hz but RPM would be nice to have much higher. That way we can make the memory go a lot further both in terms of ...

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!

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 ...

silly me, its all here

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

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

Also did you have to remove any PCB to feed the cable underneath?

Ah nice, thx for images.
And deutsch as well
Maybe that is the go and I don't get greedy wanting the other pins on the digital side. Saves me pulling out the PCB to drill the case out.
And your image shows ...

ah woops

and now wonder if I should do analog connector at the same time, uurgh.

Great, thanks Spunkster.

I might as well keep this thread rolling if I'm going to do this in case others have any interest.
So looking at the board the pins on the digital connector on the PCB are
- Ground
- Digital out
- 2 digital inputs (+ & -)
- 2 rs232 (transmit and receive)
- 2 CAN (high and ...

On a KPro4 there is a 10 pin connector internally that includes CAN and a punch of other pins. How are you guys getting that to the outside world?

Seems like two options
1) I make a little harness from the 10 pin connector internally and cut a hole in the side of the case for a 10+ pin plug (or ...
