Title: Exhaust Gas Regulation not working? (firmware1.2.30)
Post by: black on September 21, 2017, 07:14:14 am

Hello,

why is the exhaust gas regulation not working - EGT regulation is set to 984 deg. Calculation table is showing the right calculation (lambda -0.1 and boost - 7kPa but ECU values do not change. So no effect  :o

I can scroll to the right ( "boost target curve (RPM,GEAR) = 298 kPa - dont you? :) but I show you the curve ;-) thanks

ok, maybe find some spot where it's not over 5 degrees... because that vt values, not ecu. it should be working properly and 200% it is working as it should.

when you are using 3 year old fw you can find even more interesting things

After lowering threshold to 960 deg - its clearly working now. Thanks.
