We put bigger nozzels into alfa 1.9jtd 105, from jtd110 or 136, they are about 20% more flow, so car now runs at 1100 rpm at idle and smokes too much.
I know that we need to change injection duration map can
someone help me which are duration map locations
heres original file http://upload.horvat-varpol.hr//file...Bin891-733.zip (http://upload.horvat-varpol.hr//files/1/mape/891-733.Bin891-733.zip)

Original injectors were 0445110002 and new ones are : 0445110119

can I copy values of duration map from jtd110 ?

works fine in idle, 1st,2nd gear but in third and 4th gear -5
between 2000-3000 some seriuse problems at full throtle
like every 200rpms cars stops and starts accelerating

I see that you change two maps by +25%

You must copy duration maps with axis from 110 cv to your file and all will be ok :)

i don't think it will be succes from the fist adaptation
i need to try some solutions until it will be succes 100%
it's not chiptuning,it's a new programme for ecu to drive new injectors
try this and repport; same pw
