IRC Auto Blipper / Quickshifter

[slipliner]

Ive just had an IRC Auto Blipper / Quickshifter fitted & the guys that fitted it are having problems.
It will downshift but not upshift.
Can anyone shed some light & throw me a help line ?

Timing needs adjusting, i had opposite problem. Best setup on a dyno. Adjust the L setting to adjust the loading required to change gear it's probably set too high. Some work out of the box some don't. Standard setting says 22 try less
