DIY LTCC or similar system for LT1s

[spfautsch]

But I would like to give myself alternatives as well as get back on the electronics design horse.

It sounds like you have a bit of a tinkerer thing going on and I can certainly relate to that and have nothing but respect for you. For me, it's catching up on the hot rodding I needed to do in my 20s but got married and had kids instead and was broke for the next 24 years. I remember reading the stories on the LT1 in the early 90s (which were always a footnote compared to the ZR-1 / LT5 stuff) and thinking that's the smallblock I'd want to build if I ever had the means.

Perhaps next week I can get those waveforms you need,

Don't worry about me - I have enough to work with here. The only thing that would contribute slightly is seeing dwell at (above your rev limiter) and I wouldn't ask you to stress your engine that hard for something I've already determined isn't going to be "enough".

as well as limp mode behavior when the Hi-res signal is lost.

I'm not too worried about this at the moment. Honestly, my take on "limp mode" is that if it doesn't start after 3-4 seconds of cranking something's broke - call your significant other to come get you so you can tow it back to the shop. This isn't a grocery getter. If I can conquer step 1 completely I might consider time based sequencing and the possibility of limp mode, but it's not something I'm going to lose sleep over.
