Autotune always reads "Out of window" or "0% correction"
 

Is there anything to autotune more than enabling the feature? Whenever i enable it, it seems to make no changes, it's almost constantly out of window, and the rare times it does go into window, it's never changed anything that i can tell.

Can't find any documentation or instruction on this feature, please help.

The way to adjust the window is a bit complicated. Go into your project's folder. Open the mtCfg folder inside this directory. There's a file in there called custom.ini. Open it with Notepad or a similar text editor. You'll see a block that begins with [AutoTune] and a couple of computer-speak if-then statements. You want the block that has an if statement that notes it's for MSnS-E. Inside that block, you'll see a set of notes like this:

xLimits = 1200, 5000
yLimits = 20, 90
zLimits = 10, 150

The xLimits control the RPM range where AutoTune works, and the yLimits control the range of MAP values where it works. The zLimits controls what it can set the VE table to. Adjust these numbers to put the AutoTune range where you want it to be.

Another possible solution: Switch to tunerstudio and see what VEA live can do for you!

The VE LIVE autotune is admittedly better.

Heh, you say that like it pains you :P.

no, I say it like I hung out with a MS developer over the weekend and we talked about it.

Matt: Thank you very much! i couldn't find that information on the quick start or the document on the MSPNP site, thank you for giving it to me!

Jeff: How is VEA better than the Megatune autotune feature?

Edit: Brain replied while posting this.

Alright, edited my ini to the following data (in the 90-93 without AFM):

xLimits = 1000, 8000 ; RPM
yLimits = 20, 90 ; MAP
zLimits = 10, 200 ; VE

Still doesn't seem to work, shouldn't that be entirely open?

pppssssssssssssssst, use tuner studio.

When i try to open the map i have setup for my car in tunerstudio, it opens with like four errors, so i've been wary of using it.

did you look at the errors?

4 Warnings:
Warning: MSQ Units Mismatch for maeRates4! kPa/s found in current configuration, ms found in MSQ, values were not converted to new units.
Warning: MSQ Units Mismatch for taeRates4! Volt/s found in current configuration, ms found in MSQ, values were not converted to new units.
Warning: MSQ Units Mismatch for afrBins1! Volts found in current configuration, AFR found in MSQ, values were not converted to new units.
Warning: MSQ Units Mismatch for afrBins2! Volts found in current configuration, AFR found in MSQ, values were not converted to new units.

These are the errors.

so ignore them...

This is what I do :giggle: I like tuner studio SO much more than MT....now if I could just get VElive to freakin work...

So tried tuning with TunerStudio today, but it's telling me the O2 Filter is out of range.

Looks like it's setup for a narrowband, but the EGO control looks like it's setup correctly.

If this were MegaTune i'd guess the config file needs to be set, but i don't see any option to play with the config in TunerStudio.

Any tips?

Did you create a new project? If so, the setup for the wideband is in that menu. If not, it is in file->project->properties or something like that.

maybe you should read the "using tuner studio guide"?

Would absolutely love to, just haven't seen it either in the program or where i downloaded the program from. Would you please point me in the right direction? i tried googling, but nothing came up that way either. Thank you for your assistance.

it's a sticky here: https://www.miataturbo.net/megasquirt-18/using-tunerstudioms-tuning-megasquirt-guide-40159/

Ah, thank you. Never gone in the normal Megasquirt forum. :)
