I was going to jump them from 3/4 across the back of the board to DB-15, but that's a little excessive heh

yup, inputting an input into a free input is still relevant.

Cool, I also found in another thread that I should probably reinstall R12. I was following the diypnp directions and pulled it.

You'd still want to calibrate it, but manually, since closed/open will give you the same value. you'll want to calibrate it so the OPEN value is above the value that you're getting at closed; whatever it may be.

OK. I was getting an error that says min shouldn't be more than max, so I stopped. I'll give that a go.

Then you dont have a 1K resistor between TPS signal and ground.

You can see it dangling over by the N72 pins, maybe I didn't jump it right. From TPSSIG to a ground on the harness, right?

Did you calibrate it?

Nah, not yet. I didn't know how when I was at my shop, and I had to put the miata back together because I hate driving my truck now. Now that I know how, I don't think it will be a problem.

My MTX-L goes from 0-5V, and it seems most the built in widebands run 1-4V or so. Should I interpolate and use values not at the extreme limits? Can't find MTX-L on my firmware, only LC-1. Think the signal is the same for both though...

what are you going to put a/c out on? ALED?

I got em backwards, Aled is rad fans, and wled is AC up like this.
