@Bloopdog Re-Ran yours as well.

 

Yo, I just installed some id1050x's and an afpr as of 10min ago. So I theoretically fixed my fueling issue. Once I get things rolling again, I'll throw you some logs. Currently struggling to stay running lol.

 

Good deal. I'd start by smoothing your entire table in tuner studio as a base.

 

Try and flash this it has your dead time and new injector settings. @matmsm

 

Hey, I'll bite. If only for "science".

 

Rich across the board...

If you want to go another round up to you after this, drop your .msq along with new .csv. I am curious on a couple things that the extractor flagged.

 

Round 2...Just cruising, no WOT pull(s), but I did get into 200+kpa at part throttle at one point. I've included ther MSQ file this time.

 

Your Mat Corrections are backward, you are adding fuel when warm.... My extractor correctly flagged it.

Below 100 you remove fuel, above you add, you have the inverse going on. That is exactly why you are rich across the board.

I took the MAT curve from the base tune for a miata from here and added it to your tune. https://trubokitty.com/#/tune

I also put your fuel back to the original one you started with, if I pull fuel from that table then it will cause you to be lean -- not sure how long this has been on your tune, but I'd rather start at the base line that you came in with so there will be no issue stemming from anything I did .

Now that you have your original table back in and the MAT no longer adding fuel when it should be removing it, you can log again and we will try and dial in your VE table where we are not chasing phantom fueling issues....




Edit:

Here is a link from this forum explaining....

Section 8.16 in the .pdf I uploaded explains what I am talking about.

 

I'm aware that my MAT correction is "from the upside-down". I was experiencing a situation where t was leaning out when the ambient temps started climbing and I spent a LOT of time trying to correct it via the VE table, with no success until I inverted the MAT correction. I'll revert to your "correction" but if I see that same condition again, then I'll go back to the upside-down and move on with life.

I don't know if this is relevant, but I have converted my NB1 to a full-return system and I also have a rising-rate FPR in there to account for increasing the fuel pressure under boost. I don't know if any of that has any bearing on the MAT correction, but I didn't have this issue with the AFRs going lean when the IATs get high (especially when the ambient temps are high) until I went full-return and put in the RRFPR.

 

Going over your tune I think I found the issue:

• MAPdot never exceeds 934 kpa/sec, and 99% of it is under 350. Frames above 1000: zero. So bins at 1285/1719/2240 fire literally never.
• TPSdot never exceeds 520 %/sec, 99% under 270. Frames above 800: zero. So bins at 821/1310/1834/2296 fire never.

Impossible numbers.

So if you want, after you change the mat, put your original fuel table, make the changes to your AE curve, then we can re-log and tune your VE table,

I suggest that you set them like this:
