Nearly stalling when starting from cold

[Tony C]

right been playing again,
she fires up when cold then stalls after a few seconds and then on restart fires and idles around 800-1000 rpm,
which is better than before,
im heading the right way slowly :D

Increase the size of the afterstart parameters...  They do seem to need to be large.

[Tony C]

which bits Dave?

[dnb]

In MT in priming/cranking/afterstart in the settings menu there are 2 parameters called afterstart enrichment added value and and afterstart enrichment scaling.  These need to be fairly big, otherwise you risk actually adding LESS fuel than when the car is warm!

I don't remember the actual values I use, but I will look at the car at lunchtime.

[Tony C]

cheers Dave,

[dnb]

Didn't get out at lunchtime!  Damned people wanting me to tell them what's wrong with their radars ;)

I use 70 for the scaling and 30 for the added value.  It seems to work as I can start the car with no throttle now.

[Tony C]

hi mate.
is that the afterstart enrichment scaling at 77c % you set to 70?
and afterstart enrichment added value % to 30?

[dnb]

That's it :)

[Tony C]

[Tony C]

I was wondering that did you get this problem cured?

[Tony C]

so left it as was,

[Tony C]
