search online i found instructions how to get into calibrate there is a sequence to press buttons on the display console and i think may also be in operator manual.i have searched online and now cannot find the page i used to reset the calibration on a 8080.

What are we calibrating?

When I used it it was for throttle calibration on a jcb 8080 that would not open throttle much as far as I remember. It did solve the issue, but I think the fault the op has can’t be done through console? In the machines manual it showed a step by step of how to calibrate throttle. I don’t recall any others.

On an 8080 can you send pics of screen and buttons, include throttle dial

I am no longer working am retired now, there was a sequence on which buttons to press and the order to do it once that was started the throttle was put in lowest position then I think ack button pressed then a screen prompt full full throttle position and ack again and that was basically it. The machine had the older type console I think a 2004 machine. It did make the machine rev more and would also boost the revs if tracking. It made the digger much better to operate and at a better speed if needed, I guess it would also work on older js machines with the same type console. I will try finding a pic online as I don’t think I took any back then.

This was console type and a YouTube clip of calibration if it helps.
