v3/4 Plugin Hard cold start

Recommended Posts

HI all 

I'm currently tuning a mates 1996 Subaru legacy with a v3/4 plug in and i cant get it to cold start correctly at all 

It will  take a long time to crank over for the  first start in the morning, after the first start it will start much better 

I have played around with all the cold start settings making both small and drastic changes to see what difference it makes, but none were observed 

I have also lowered the trigger voltage table from 0-1000 in order to maybe pick up sync quicker but also has not worked 

i will include the tune file and a starting log to view 

Any thoughts are appreciated and criticism to any other aspect of the tune is welcomed also 

 

Thanks!

It looks like it syncs almost instantly in the log so I would be concentrating more on fuel settings.  Comparing to our base map it has about twice as much pre-crank prime and crank enrichment than yours.  Most other stuff I looked at seems pretty typical.  So try the map below, I have just imported these two tables from the base map.

With the stock settings it is much better,  but is still struggling to start like factory, it doesn't seem to jump into life like normal.

I was thinking of stepping up the starting step a bit, but really unsure how to figure out what the engine wants when it starts
