Default so how well does your car start?

It starts first time, but it takes about 7 cycles before it fires, regardless of cold or hot. Played with cranking duties a bit, but that doesn't seem to make much difference.
My Link ecu used to fire *instantly*, it even didn't take a comply cycle to start, almost like an on/off switch, really. Scared the crap out of me the first time I started the car .

Mine takes about one full cycle. Even with the stock CAS, should be about the same.

I do typically wait about a full second between power on and hitting the starter. Takes the MS a little bit to boot up and fire the priming pulse.

My turbo car onMS starts just as quickly and smooth as my stock 1995. I didn't spend that much time on it either...ms just works I guess.

Mine starts fine... I just had to mess around with the cranking pulse widths a bit.

Guess I'll need to play more with the prime and cranking pulse. No matter what I do, it always takes 7 cycles before it starts. Lowered and raised them by as much as 50% without noticeable differences. Mmm. Will keep playing with them and see what happens.

Im starting to think we really need a dedicated MSII section for those running it, not to mention the new DIYPNP will be using MSII as well.

My car starts as soon as I turn my key. It actually starts faster than my 05 Acura mdx

MS1 with NA CAS - Sometimes instantly, others maybe 2-3 turns, probably depends on where the engine was turned off.
MS2 with stock 2002 sensors: Like Frank, 7-8 cycles. It usually tries to catch on 3 or 4 but doesnt quite make it and you have to keep trying for another 3 or 4 cycles. Then it catches.

Hi guys. Newb question. Mine starts in 3 or 4 cycles but as soon as i turn the key to on (without cranking) i always hear what sounds like pressurized air escaping quickly- almost like a muffled bov. Any thoughts?
