a q45 afm will loose your low down resolution but you should at least be able to get it to idle correctly
start again completely
i think your k constant should be 27398
and latency should be 580 unless there is data showing there is a different lag time compared to stock injectors.
set ttpmax to 255 all across
and ttpmin to 0 all across or i found 2 kept it steady
then basically make your map completely flat in target afr's
14.7 to the middle then 12 afr to the end.
now open the maf translation map and with the car running you will which cell its in highlighted in green
you want to highlight the green cell and the 2 to the left of it
then you need to press -, it may take a while but it should bring your afr's to 14.7 as commanded in the fuel map
i've found while on the road you need to highlight the cell in green and the 2 to the left to keep it all smooth
now adjust a few low sections of the map translation parked up from idle to 3000 ish till you get the commanded target afr in the fuel map
now the hard bit where its alot quicker with 2 people one driving and one adjusting
before you go driving make sure you map is safe by taking out a few degrees across the whole map.
then simply drive the car at various speeds and throttle positions and adjust the maf translation map till your getting the target afr in the fuel map on your wideband.
when you start getting to bigger numbers we went down or up in 500s etc
before you do this tho make sure all your boost pipes are tight and exhaust isnt leaking
when you get this sorted you will be able to command a target afr on the fuel map and get it on the wideband this makes things hell of alot easier
also the car will drive alot smoother as the map isnt rough anymore
here's an example of map fuel map now its been fixed
