Thank you so much! I did that and it idled like a champ just rather rich. Like 11:1 but it was steady

No problem, I'm here to help. After all, I did build this ECU.

One more question. Now that it idles right, I should still mess with the start-up idle settings to get the afr's right correct? And then when I drive it, I can just let autotune do it's thing?

Ok, here is my current tune and a log of it idling. I also gave it some revs at the end of the log.

don't do any tuning till all corrections are off, once they are off you can tune in the idle area as well as the VE table

Ok so I just took it for a drive. It went smoothly but it wouldn't add fuel when it went into boost(No I didn't hit mad boosts, nor did I stay in boost long, more of a hit 2psi and back off immediately). I was driving with autotune on. It idles pretty high for a few seconds then lowers, but afr's seem to be good. I guess next I'm going to swap in the rx8 injectors and probably screw myself all over again. I have my current tune uploaded.

yeah swap the rx8 injectors in and put in proper injectors settings for them before tuning anything more.

I will do that. What do you mean by proper settings? Like required fuel?

The base map he sent me was actually for rx-8 injectors

So I swapped in the rx-8 injectors. changed the required fuel to 6.9 and it fires up and idles pretty darn nicely. I will attach a log. Going for a test drive now.

Took it for a test drive. Still won't add fuel in boost. I'm not sure why. Probably cause I'm stupid. My tune is attached. It also idles really high for a couple seconds and then settles down to about 1100rpm.

I think that issue might be due to the fact that I'm an idiot and made changes with the car running. When I restarted the car it seemed to go away but I will grab a log if it happens again. Now I still just got to figure out how to add fuel and stuff, I feel like this is all simple and I'm missing something small.

I can't see anything in the map that would prohibit the autotune from adding more fuel.

Me either, not that I really know what I'm looking for... I was looking at the filters for autotune. There is one for minimum coolant temp but when the car is warmed up it shouldn't be an issue. It starts to richen up when I near the boost threshold but then goes lean again. Also my fuel map looks disgusting. But I don't really want to just go in there and guess at what I'm doing.

What does the fuel load gauge read with the engine off and the ignition on?

Ok so the map sensor is reading fine. It should be ~100% with the engine off. You may want to change the cell change resistance to "Easy" for quicker results.
