Just built and installed MS3 via Braineack's guide and I've been pretty successful tuning the VE table, my idle is very stable (when it starts haha), now I'm just trying to nail down startups. Attached is a log where I needed to try three times to get it to start. The first time it never exceeded cranking rpm, so clearly the cranking pw need to be adjusted for this temp. The second attempt had the engine die as soon as ASE+WUE fuel kicked in instead of cranking fuel. The ASE and WUE fuel was about half the pulsewidth and the motor just died. This seems like not enough ASE to me? Am I interpreting this correctly? See my tune and log.

Starting to figure it out, my cranking pulse widths are probably way too high at the moment, it was actually a too rich condition.

This morning I tried a start at 60 degrees CLT. Cranking pulse on the base map was ~260% at this temp. For the first start I dropped it to 100%, crank but no start. Bumped it to 150%, boom it started. Next start at this temp I'll probably start at 150% and go up in 25% increments if needed, try to hone in on the correct crank pulse. I'm assuming it needs at least 150% for a first start attempt, as this morning the motor had some extra priming at the 100% crank level prior to trying the 150%. Rinse and repeat for all other temperatures.
