Anyone try reflashing since Uprev added the new cranking tables? My startups seem a bit better (still rich but no stumbling yet) but I haven't really tested all extremes yet.

^^^ yes sir, just tuned twin turbo HR with a factory fuel system set up and 800cc injectors and it fired up hot and cold perfectly. Pretty much just multiplied each table by .5 and it seemed good. Still also entered the same values that I enter in for the cranking enrichment table with large injectors. Didn't get a chance to do the 100 degree day with a hot start but I think it def will be better.

Cool. It definately starts better with no more stumbling on hot starts, but it's still pig rich on cold starts, starts around 12, dips to 10 for about 10 seconds before switching to closed loop and climbs to 14.7. We have to be missing a table still. Something like startup enrichment not just cranking.

^^^^ You might wanna take out a lot more in the cranking enrichment table then. After I get the all tuned in I will start them....Air/fuels will sit at 13.5 for a few seconds and then come up to 14.7

Even on warm starts still getting a small puff of raw fuel with cranking enrichment less than <10%. My base fuel pressure is probably higher than it needs to be, but I didn't notice it until too late, not going to retune to a lower pressure now.

^^^^ sounds like you are right there...lil tweaking and you will have it pretty perfect I'm sure

I'm a dumb ***! When I first looked at tables 1-4 and the values appeared to be very low (like 5-10% in the hot areas) so I assumed they were already scaled to match my main table settings.

Took a look at the stock ROM and realized they are actually stock values! Cut them all in half, and my startups are PERFECT now. Just like stock at any temp so far!
