Looks like the same issue i had with my UD do you get a check engine light? I use to have power loss and ended up being injectors fix that and a couple days later my HPFP went bad after that the truck works fine where are you located i have the ud software

You need UD Data Link software to scan the truck and see what codes you have registered Check if the ITV isn’t stuck or any clogged fuel lines maybe bad scv or bad turbo

You should check if your ITV is drilled also check the scv valve if you have the updated part check banjo fittings and fuel lines maybe clogged

Because there is not alot of UD support with scanners and the dealers here have more HINO support and maybe they can remap my ecu since i have the 2008 model it came with alot off issues including the un modified ITV and creates alot of soot

Hello i was wondering if the 2008-2010 hino 268 ecu would fit my 2008 UD 2600 ? I know they share the same engine but i think UD blocked the ecu so only there software computer could diagnose the truck ?
