Any new MAT correction trickery
Or is everyone just converting the new table to incorporate their old values?
As I read it: To get your old values into the new value. Lets say at 45 degrees F Your old value is 99% or -1% The value in the new table is -110% Your old MAT factor is 50% old value in new tabled would be -104% .5 % 10% = 5% minus the 1% that was being pulled via MAT correction table. |
did they make a change to it or something?

in the latest stable release they put the MAT correction factor and table into a single table. When you install the firmware your MAT correction table goes away and you get a default table that represents the ideal gas law with a 100% factor. You then have to convert the new values to your old values.

I just made myself comfortable with the new "exposed" MAT correction.
I made myself an Excel spreadsheet, with the standard values of the MAT correction, the 50% correction values and my old correction empirical values... Look what I get as an resulting line... https://www.miataturbo.net/attachmen...ine=1361266469 The resulting line nearly equals out all the corrections... (and the -40°C and -20°C values are estimates...) I think this is interesting... (and how often did I read here - "we need to zero out the corrections..." - I think Brain is telling this since ages...) |
I posted that a while ago:
default curve: https://www.miataturbo.net/attachmen..._mat_curve-jpg What a "50%" reduction would look like: https://www.miataturbo.net/attachmen...t_curve_50-jpg What I'm running: https://www.miataturbo.net/attachmen...rve_custom-jpg looks like our end results are very similar. Basically the table is total corrections table now, instead of before where the table was a corrections table for the built in corrections. It makes much more sense to have it the current way. |
Oh must have missed this - but nice to see, that you get nearly the exact results...
Someone else did this comparsion? Rev? |
I just plugged in numbers I thought would be a good starting point :)

Can someone help me undumb myself. I cant for the life of me find the MAT correction table in tunerstudio. Where should this be? I tried turning off all enrichments when I started tuning, is there a way to turn this off? I bought the upgraded TS for my laptop and do not see it on here. I do see the menu on my nonupgraded TS on my desktop.

Don't mention which MS you have or firmware version.

Yup just dumb. I swear I checked all of that submenu, o well. Thanks for the help!

Forgive me for necro'ing this thread, but I am wondering if we have found a better MAT correction curve since then? I am kinda battling this right now and am about to plug in Brain's curve to hopefully stabilize my VE table.
