As soon as I can find myself a good Data Aq. card, I'm going to get
one. I spoke to some of their engineers at SAE, and it seems pretty fail
safe. The problem is that I'm too cheap - the new motor will have AL
heads, not iron, so it'll use a different spark plug, and I'd rather not
burn up $200 for the next month.

Sure, among other things like fuel maps, and you could probably
analytically get rid of the small things like the minute tip-in stumble I
have,
etc...

The module was $600, IIRC. If anyone has it, I'd love to hear feedback.
