Default Convert cranking ms to pw %

I'm having trouble getting my MS2E started. It's been penguin-butt cold here, so I'm fighting a losing battle. I know the mantra is to just copy DIY's numbers, but their stuff is in milliseconds and the MS2 uses something called Pulse Width Percents.

I know PW% is related to the REQ_FUEL number, but does anyone know how? And how are the millisecond numbers for the MS1 related to REQ_FUEL, injector size, or what have you?

I'd really like to get this puppy to fire, any help would be appreciated!

I modified the stock values slightly but anyway, this is what I'm running now. Granted it dosn't start right when it's freezing, but it eventually starts.

The cranking pulse width is equal to Req_Fuel (which is already in msec) times the percentage.

Thanks guys!

Now why wouldn't the software do something useful like add the unit of measurement next to the Req_Fuel? It looks like some magic number without it.
