Title: 1.8T ME7.5 hot start fueling
Post by: Rocky on July 18, 2016, 11:49:00 AM
Hi friends

i have hot start problems on 850ccm 1.8T mafless with race camshafts.
i see there is a bit too much starting fuel.

-lambda on idle is near 1.00 but with little misfires. (i know that lambda readings with misfires is not reliable:))
-idle rpm raised to 1000rpm.

i have tried to lower FNSSM with no success..

Regards

log tmot and tweak KFFWL

source x TMOT   --->>> GGTFM EIN Motor-Temperatur
source y TMST   --->>> GGTFM EIN Motorstarttemperatur

what is the difference between Motor-Temperatur and Motorstarttemperatur;)

One is the temperature when the car was first started, other is tmot (current temp)

How long after starting? if within ~50secs there are afterstart tables

In ME7. 1 it is always used, iirc. I don't know about 7.5
