Adaptation 1.9 TDi BKC with arl injectors and turbo

by **arceoxis** » Fri Aug 28, 2020 3:36 pm

Hello, I'm trying to adapt my stock software to run 1749vb fron arl and al injectors from arl too. I attach what I've done, I have copied the maps from arl to mine and adapt torque maps taking in account tq2iq. I have modified pressure axis in torque limiter to be the same as in arl ori, but I'm not sure if this is ok, I have set iq limit by map to 60 as in arl ori but I'm not sure neither.

I have tried this and the car runs ok from 3000 rpm but in low rpms it doesn't run good, I mean it is slow. Could anybody help me? Thanks.

Did you try to move N75, boost, boost limit maps and SVBL?

Also with ARL turbo MAP sensor should be replaced (after sensor replacing MAP linearisation and diagnostic message type need to be changed too).

Now I can see your file, is MAP limited and you have filled it with 60mg, you can start with map from 105hp and correct last column to higher boost and fuelling.

TQ limiter at 551 1000 and 1250 RPM is a bit strange, in this range torque should rise.

NM to IQ can be extrapolated to higher values.

Make logs, especially boost log, because PID maps may need tune too.
