I've spoken with a local dyno tuner who has never worked with MS, but tunes a lot of race cars that use other ECUs. His dyno is not a steady-state type, but he claims it makes no difference. When I asked if he thought he could tune the MS, he said that every ECU he has seen is similar, so he thought he could. When I asked how he could tune ignition timing across all of the individual bins without a steady-state dyno, he said "timing's timing.... doesn't matter".

These answers seem a little "seat-of-the-pants" to me, but I don't know enough about the procedure to separate BS from fact.

I'd like to get it running well enough to drive cautiously (no boost) so I can drive it to a shop for larger exhaust work before going on the dyno.... then I won't have to tow it. I guess I should use auto tune so I can drive to the exhaust shop and dyno.

I also need to figure out how to tune the start/warmup parameters so it'll start easily and idle without throttle input when cold.

Lots to learn.
