The first start of the day always fails. It will start, and then as soon as ASE is done, the engine dies. The second start always takes and doesn't really even act like it's going to die.

I have tried both with the first start enrichment on and off but that doesn't seem to make any difference.

I can let it sit for hours after the engine has warmed up and it will start first time, but if left overnight it will not start properly the first time.

Any suggestions?

 

Mine does the same since installing my 550s except it takes me like 3 or 4 tries that first time of the day. Also, mine doesn't even finish the 30 second ASE before it dies.

How long is your ASE and are you running decay or fixed then decay? I have had much better luck with fixed then decay.

 

first cranking settings, then ASE, then warm-up enrichments; in that order.




waytne_curr, did you compensate with your cranking settings and req_fuel once you fitted larger injectors?

 

Yes I did. I think my cranking settings are fine since it catches on the first try. I figure I just need to increase the ASE a bit.

 

I turned MAP mode to normal, else it would either die or oscillate heavily till the the MAP timer ran out...
