accord 2.2 cdti injector correction quantity
- Thread starter hondansxr
- Start date
Interesting, I would probably start by throwing some injector cleaner down it. Also check the manifold for leaks
going to do a terra clean on it in new year got to order some more fluid for machine will let you know if it changes the settings . noticed the other day there were a set in the boot (inj x 4 ) so dont know if these were for change or have been changed ?

Those figures are the "fuel quantity which ECU corrects" figures, meaning the ECU has detected the deviation and is already making the necessary compensations. Somewhere on TA there's an 'HDS' thread where I posted pictures from when freddofrog and I checked my injection quantity corrections using his HDS... mine were approx. -1mg, 0, +2mg and -1mg (the range of correction appears to be +/-5mg). Sorry, but at the moment I'm unable to post links.

Thanks Brian (again!).
It was jayok in post #19 (and Fahad in post #20) of that thread that eventually cleared up my confusion about these correction figures being nothing to worry about... used injectors will never be spot-on, so some level of correction will normally have to be undertaken by the ECU. The system is pretty smart and I guess you only need to worry if the correction figure goes off-scale!
