Does the MS-II extra fuel while cranking?

 

The MSI Extra does. The amount of fuel is determined by the cranking PWs. No idea on MSII.

 

Any idea where that setting is in the software? There seems to be a temperature dependant setting, and while it fuels WHILE I'm setting that, I wonder if there's something else I'm missing.

 

This is just a random table example. We adjust our cranking fuel by going to Cranking/Warmup, Cranking Settings.

Well, thanks - at least I don't feel like a tool. Mine has the same chart (with a nice graph!) but none of the other settings. There's a crank pulsewidth table, but it seems to be being ignored. Guess I'll keep digging. Thanks though!

 

Actually, ok, priming is in MS. Cranking is in %. And most of those are in the hundreds, they all are. Like, 180% to 430% - I imagine it just means that much richer than the running pulses. No idea. I've set them all to numbers in the teens, I guess I'll get out the stim and try it

 

Er, thanks for all the help. I think I've got it. This is the second problem that just... "went away", litterally all on its own.

I'd powered it on and off, loaded and unloaded settings, etc. But now nothing I do can break it. Yesterday nothing I did could fix it. Maybe it takes longer to kill the power for a full "reboot" than I thought?

Is there a reboot/memory clear button I can jump, or way to drain power out of the caps?

 

I was reading the MS-II Extra upgrade manual, and I think it said something about how cranking pulsewidths are a percentage of REQ_FUEL, and that it defaults to something that's mathematically in the ballpark for like, every motor out there, and that it's better not to mess with it until after the motor is running.

Thanks, yeah - I let it all go back to what it was after trying my little change.

Now, the issue is weird: I hooked up the ignition outputs, and the lights get really dim when there's huge advance.

For some reason, my JimStim is taking my up to something silly like 16,000 RPM - so I assume I'm reading the crank wrong. But the LEDs for ignition get dimmer and dimmer, then go out. But then: They come back on, bright as ever, much higher in the RPMS. No idea why, none at all.

I want to figure it out!!
