Are the version 3 tunes also updating the older models (13-16) as well as creating model year 17 tunes?

When you are open loop the MAF value determines how much fuel is delivered in order to hit the commanded AFR. The fact that the measured AFR is lower means that the MAF scaling is off.

Oh wow that would be amazing, then how would I go about scaling it? I just took a look and the MAF voltage was reading 0 all of my logs, is that normal?

It probably has more to do with the miata having a stronger install base.

There's a long thread that's worth reading a couple of times that @steve99 started.

One other note, if your MAF voltage is always zero you need to update your OFT.

But the Miata sucks eggs.

My OFT updated the first day I got it and plugged it in to my computer, all of my logs have showed 0 on the MAF voltage, is there somewhere I can go for the latest update?

My HW version is 03.35 and FW 01.45
And CD: P9029

Are you logging maf voltage? Go through the mag scaling thread and run it through the vgi mag scaler. What are your fuel trims like?

Ya I'm logging it, but in all my logs it comes up as zero. So I don't think I can run it through the scaler without that?

And they look like LTFT is almost always 2.34 during WOT pulls with no STFT

*Nevermind I was using the compare tool before and it left the offset one up the actual two tables are here:

Double posting because I found something odd. There are only 9 tables different between the Stage 1 and the Stock tune and here is one of them. Could the Stage 1 values be flipped?

If its K00c rom the logging ram address is likely incorrect you will need to contact the oft guys

AF learning limits ie LTFT are normally +/- 40%

Im not sure what defs you using but it might be a scaling/display issue as the 40% may be represented as 0.4 instead of 40%

or it might be a typo

diff between 40 and 4 is 36, hard to know without seeing roms and defs

Nothing about this 2017 support has been smooth. Looks like they find the cheapest least time consuming method to make this functional. Tunes are ok, better than stock, but not great.

So it seems that maybe for the 2017's we may be better off just Dyno tuning with ecutek? I have a 2017 and want to get the OFH and OFT but the 2017 support seems lacking.

I haven't seen where Dyno tuning with any tuner on a 2017 is very effective.
