Hi,
I have a problem with cold start the car after the last day i drive on lpg.
Car start and shake violent for 5-10 second (like it is missfire very bad and an strong smell of petrol at tail pipe), after this 5-10 second the car run ok.
If I run car last day on pretol cold start are perfect.
I try colect maps again but same problem, car runs ok with load at any speed or load but what i can see it is my idle long fuel trims are a little bit off:
Petrol long fuel trim it is about +3%
Lpg long fuel trim it is about +1% but this free of load.
Now i have a few questions:
1.when i trun on my headlight long fuel trim goes up to 10% and here i think is the problem, how to prevent this?(if i trun off light fuel trim goes down to 3%) this only happens on lpg.
2.if my petrol fuel trims are 3% i need to set also on lpg to be 3% ? or need to set -3% ?
3.i attach my curent setting, between 1 and 3 ms there is a steep curve it is ok? if not how can i set to be ok?
