You should probably find a diagram. Then use the diagram to ensure that you have your pigtail wired right, and that it's got ground/voltage where it should.

Good lord,

Black/lt grn is ground, dont fuking touch it... or rather put it back where it was.

Type "miata schematic" into google and literally a 100+ results of factory wiring diagrams. This thread may confuse you more than it helps you, but for the cognitive thinkers among us:

When I say switched I meant swapped. Didn't think there was much of a difference, my bad. And there's just three wires for it the red being the 5v, the black being the ground, and the green being the signal. I switched the ground and the 5v wires around, which is what I thought I was supposed to do. And I also read that PNP Pro already has a jumper for the tps, is that true?

That'll do it.

Don't touch the middle wire. Just don't. Well, now that you already did, undo that. Then don't touch it again.

Reading up and it's saying with the pnp pro that it'll need a jumper

So using powers of reasoning, do you think you need a jumper or not?

Going by what DIYAUTOTUNE has on their website, yes I'll need a jumper

Make it happen. Feels like we're making progress today. I mean, just look at my post count growing!

So you can be even dumber and fail even harder?

I would consider this to be a love/hate relationship.

Seems to be pretty spot on. Ordered the jumpers as I opened up my MS and there is most definitely no jumper on the vtps nodes.

Is this car revving yet?

LittleCarBigFun 05-18-2018 07:22 PM

Not yet, unfortunately. I'm going to try and run stuff on MAP only until the jumpers for the tps come in.

EDIT: Turns out I didn't configure the Megasquirt to run on the GM IAT sensor and that was preventing it from revving. She'll rev up now but still has a fair amount of hesitation. Just need to mess with the Fuel VE table a bit it seems
