How to Megasquirt your 3G Hemi

Thanks for the kind words, joe!

My kPa at idle is around 70 and fairly stable. Drops down around 50 at 2000 rpm. MS3x has an ITB setting that uses an alpha-N table for idle and low rpm, and a speed density table for everything else. I'll probably give that a try at some point. Honestly the car idles great right now (when warm), so I may not need it at all. I've still got a fairly small cam in the motor (218/224). I would imagine the ITB setting would be needed with more overlap.

I've been finishing up some other items on the list, but it's almost ready to truly drive (I've only run it around the neighborhood so far). I'll run ~500 miles of street driving (break in clutch), and use that time to let tunerstudio self tune the low kPa part of the speed density table (or as much as I can get it to). I've talked with a shop with a mustang chassis dyno that will allow me to steady state tune the car, so that's the next step.

Also, I have not activated acceleration enrichment or warm up enrichment yet. I understand you need to get the speed density table spot on before bringing those into the mix.
