yeah don't rely on my map, anyway i think that one was pretty dodgy it was really lean in cruise areas to save fuel, trying to see what economy i could get without killing my power and responiveness.
Are you running standard injectors??? (mine are 210cc)
That said it should idle without problem. From memory your req_fuel should be 8ms if you run 4 squirt/cycle (which i found to be the best comprimise) and alternating. The VE values around the idle should be about 45% i think. This all works out to about a 3ms pulsewidth.
i would send you my configuration but ive since moved to 12x12 map and beta software for the megasquirt.
your problem sounds like afterstart enrichment. It could also be running off the cranking pulse. But 3 seconds sounds a bit long for that, most likely after start enrich.
please READ the megamanual (specifically the tuning section). It explains how to choose number of squirt etc. A little bit of reading always pays off in the end.
It also goes through a step by step tuning section.
it is all explained very clearly.
But to give you starting values:
Required Fuel: 16ms (worked out from engine cc's, injector flow, etc)
PWM current limit: 70%
PWM Time threshold: 1.0ms
Injection per cycle: 4 (2 works aswell)
Injector staging: Alternating
The other constants should be fairly obvious
I have cold cranking flat out at 25ms, warm cranking at 4ms.
AFterstart enrich at 35% for 250 cycles
Make sure your VE table is around 45% around the idle area (1000rpm, 40-50kpa).
That should make it idle, remember these are just starting values. DOnt expect it to work perfect. The megamanual gives you a systematic process for working these out. Ie, what causes which symtoms. www.megasquirt.info is your friend.
cheers
