BUILD THREAD 4LxxE tans controller possible project

[rfpowerdude]

Looks like the Megasquirt crowd has already done this and can be just bought off the shelf ($450). There is also a guy on LS1tech forum that did this from scratch, but is not producing anything for the market, however, when asked, he seems to share a lot including code examples.

Automatic Transmission - 4L80E DIY transmission controller - 4L80E controller and Digital dash I've updated the video on the opening page with a newer video. This controller has been successfully running for years cruising and 10 seconds drag strip outings.

If I were to do this also, do you think there will be any interest?
This would be a good retirement project...

I take it you have some circuit design/pcb experience?

The only negative to do this project is they already exist.

The pros? Could you make something that is lower cost, maybe sub $350? I assume you would target this for OBD1 or carb applications? Have a phone app based shift point adjustment method?
