Thanks for your reply. We used the FCB manual to do the calibration and everything seemed fine until we started moving the pedals. They didn't respond as I expected in that the display showed 06 at heel down and --- at toe down. I have an FCB with an Uno chip and calibration shows 0 to 127 which is what I expected to see. I assumed the response was a feature of the Uno4Kemper chip.
i will ask my friend to check the settings in his KPA though. It's a couple of years since I set mine up and I can't remember where they are either
