while not wolf, i had to overcome similar issues with my MS..
the actual cranking pulsewidths are critical to get good starting. the range i found was about 1.5-2ms wide, and outside that, no startee.. the MS has two crankign values (which it interpolates), 14.5ms@-40C, and 3ms at 77C. less than 13.5, or more than 15, and car doesn't start...
as for cold enrichment, at 20 deg, i have an extra 30-35% fuel for abotu 20deg (30% of the max injected fuel amount, ie 100% VE), decreasing nearly linearly to abotu 70C
the biggest prob when working otu cranking pulsewidths.... if it didn't start, there is always fuel there to confuse things. you either have to get it fired up, or wait till that fuel leaves the intake, otherwise when it does fire up after 2nd or 3rd time, the values used may not even be close.....
have fun
