    Great idea. Thanks!

    BTW: since I mentioned monitoring the handheld controller, I edited in a photo of its two live data display screens. Sorry these aren't the best quality; they are screen grabs from the .pdf of the online instructions. Still, they give you a good idea of what data is represented and how it looks.

    You wouldn't have anymore information on the GM standalone controller would you? I did a little googling and couldn't come up with much on it.

    Thansk for the write-up! Definitely considering this now. Not sure if this was mentioned and I missed it but what would be the ideal vehicle(s) to get transmissions out of for sbcs? Also, those transmissions controllers are ludicrously expensive for what they do. Seriously tempted to prototype something to see how cheap I could buiild one. I'm thinking I could build it in quantity 1 for no more thatn $100 and likely far less.

    They have a custom flash to turn a Microsquirt into a standalone transmission controller. It is still a few hundred dollars but not terrible.

    Any GM V8-powered car will work, since SBC and BBC use the same transmission bell housing pattern. While it could be argued that a transmission bolted to a smaller, less-torquey engine ought to have lived an easier life than one bolted to a big block engine, my 4L80E lived for 191,000 miles attached to my 454 and it is still working just fine for me.

    By all means, have at it. I'm eager to see how feature-packed and user-friendly your controller will be. While I feel my $575 EZ-TCU was a great value, it would be nice for others to get identical performance for less money.
