HKS EVC 4 problem

since relocating my battery to boot, i cant get my boost controller working any more

it comes on and all, but the boost/vac signal seems eratic (it has a monitor mode), sometimes it seems to read similar to my boost gauge other times completely different

tried self learning mode and first pass went ok but on second pass boost kept swinging from 0.8 to 1.2 bar about every second or less

tried a few different vac sources:sad:
