I would appreciate it if anyone running the FITECH could give me the settings you are running in the crank and warm up menu.

My car starts every time, but it seems like it takes more cranks than it should.

I'm curious to see what settings others have had success with.

Thanks.

Here's a good primer on cold start tuning specific to the FiTech. If your starter isn't able to turn the engine faster than 150 rpm at startup, this may or may not work for you as cranking fuel doesn't start until the system sees 150 rpm. Every engine is different, so simply taking somebody else's settings doesn't work well, you have to give your engine what it wants.

Prime Fuel Multiplier: I personally don't
like to use this at all. Out of the box is
typically set pretty high and does a
better job of flooding the engine than it
does starting it. So more than likely it's going to need to be lowered or disabled. Disabling this will make it easier to tune Cranking, Afterstart, and Warm up enrichment. Set to -100 to disable. Yes I'm serious.
Cranking Fuel. The easiest way I've
found to tune this is hold the throttle
open about an 1/8th while cranking. If it
fires up more easily this way then you
need to reduce cranking fuel. Worse,
add more. Plug reading is also your best
friend here. Let it crank and if it doesn't fire at all perfect. You can pull a spark plug and let it tell you exactly what you need to do.
Obviously this is for an engine that
has trouble cranking. Don't confuse this
for a start stall condition. I'll get to that
next.
You'll be focusing mostly on the 20f and
65f breakpoints. But remember that
everything between 20f and 65f is
interpolated. So as an example if your
coolant temp is 40° you'll need to adjust
20f and 65f. Adjust in increments of 10.
Afterstart Enrichment.
This one's pretty self explanatory. Lets
say cranking fuel is good. So you try and
start the engine. It fires up perfectly but
stalls immediately. That's where this
comes in. And it's real easy to tune.
Once it stalls don't try starting it again.
Pull a spark plug. Rich reduce fuel. Lean
add more.
Adjust in increments of 10 at a time.

Great write up. I disabled it and off to a good start. Drove it to town and it sat for an hour and the temp crept up to 190. Started right up. Thanks again.
