ok well i have a couple of questions for you guys.



last night we finally got my timing all figured out and got the car idling well. but when we go to acutally do some tuning, of the idle at least. we find that the injection times are about 3.4 when the map it is reading has an injection time of about 1.2 ish. about 1/3-1/2 of what the injection times acually are. we finally got the times we were inputting to equal the times it was outputting by changing the fuel scale factor to about 45-55.



so i was wondering what is causing us to need to do this, is there some setting or map some where effecting the injection times we cant find.



next problem! the car only like to start when you dump alot of fuel into it. so when we were messing around with the fuel scale factor every time we killed it by going to lean we would have to bump it up to around 70 to get the car to start and then could bring the times right back down. what map will effect the ammount of fuel the car gets while cranking.



the post start map seems to have no effect on the ammount of fuel getting into the car at cranking and the priming map is in time and tempature, no fuel! what the hell does the priming map even effect?



thanks-

The engine start timing and fuel map is usually the 500rpm 0 vacuum load site or if you have a 250rpm site it would be that.

That should get it started a bit easier.
