Startup ignition and fuelling.
At the mo I'm having a nightmare getting my Astra started from stone cold. It usually takes about four attempts to get it started!
1st go) Just turns over
2nd go) Turns over and splutters a bit
3rd go) Sounds like it's gonna spark into life but doesn't
4th go) Start's up fine!
Each 'attempt' I'm obviously giving it a bit of throttle. I also leave the fuel pump to prime for four seconds each time.
Does it sound like an ignition thing or an injection thing? In the first speed/load site, the ignition is set to 10 degrees. I might try upping both the ignition and fuelling and see what happens!
if there is a seperate map for cranking put it up nearer the late 20's and give it a bit more fuel.
There doesn't seem to be, just a startup timing advance tab in the ignition map. In the graph section there is a cranking graph but I don't know where it's getting the figures from??
Cranking Enrichment vs Coolant temp it's telling me?
yeah thats the ticket then, give it more advance, see what happens.
Yeah, I'll give it a go Daz
Rob, can I send my map up to you and could you tell me what you think of it? Recommendations ect? Please!!!
yeah sure, i likes maps give me a while to look around it, not looked at an emerald one for ages firstname.lastname@example.org
play with the startup timing advance. i think fuelling is covered
I'm gonna whack the ignition up 10 degrees and see what happens. The next speed site is on 25 degrees.

that main map does not come into play until the ecu demms your car to be "started"
this will probably be a predetermined rpm, maybe 500 or 600rpm, maybe you have an option, but anyway cranking wont be affected by changing the main map.
yup, but theres the cranking advance there
the extras and coolant vs ignition and fuelling are the maps for warmup obviously
let me know what differences that map makes, it might be all wrong lmao
i think i can convert the mbe grpN map into emerald speak if its still crap
just tell us what temps are wrong if it settles down
thats the cranking fuelling, leave that for now, i think your idle fuelling was too low and besides the %ages look ok
the middle one is the warmup map for fuel, top is the warmup for advance
Oh I won't touch it! Just wondering where the 'warm up' map was, that's all
