e67 420hp VS e67 525hp

[sshhh]

Hello Im tuning two cars with E67 ECUs one is a stock LS3 and the other is a crate motor ls3 525hp. The first motor I got to tune using the MAF Hi and Lo tune but I noticed the next motor only has a Airflow vs frequency only unlike the 420hp has airflow vs freq low and high.

my questions are...

Can I paste my first tune on the other ECU and get the same commands which im familiar with?

If not what are the histogram PIDs do I need to tune the MAF on the single option? The chart says X axis is Airflow G/sec and the Y is MAF Hz what is the plot value sensor I need to plug in?

The newer operating systems usually only have one MAF table, the older ones had the high and low.

Yes I see the difference, would you know how to tune the MAF on the new one?

The exact same way, log the % error between commanded AFR and actual delivered AFR against that table, and change the data in it accordingly.

On the older one I used the LTFT on the plot value sensor and X Y axis was the MAF airflow versus output frequency. When I did this to the newer one I would only get 0.00 on the data.
