Airflow HZ to Load Value?

Just wondering, is there a way to find out which load cell it's hitting by looking at the Airflow HZ on evo scan? I've read some post, and from the sound of it , it seems like it can be done? Any quick calculation to figure it out? Any advice would be great! Thanks!

Edit:
oh, wait, seems like max airflow is 1603.95, that's what i'm seeing during high RPM. I guess I'll have to order the Boost logging feature for the zetronix to get the right logs.

well the logger only hits 1603hz but everyone is probably over that mark.

i have evo scan and my afr in hz is maxing out at 1603.95 wich is causing a dive in my injector duty cycle, is this what the mas is maxing out at. it dosent make sense because the 2g eclipses where maxing out at a higher rate than this. whats the deal?

Do a search for the 2 byte airflow mod and you will see that the "clip" is a result of 1 byte reporting. On a Green at peak boost on the street I am seeing something like 2300hz near redline.

How do I see that kind of airflow. Is that what the 2 byte rpm mod is for? Also, what does 2300hz translate to in 2 byte load? I am sometimes seeing 290 load on my 100 octane EvoGreen tune.

Not 2-byte RPM but 2-byte airflow ... there are currently 3 2-byte mods ... Load, RPM and Airflow.

Hitting 1600 Hz shouldn't have any affect on your IDC%. IPW and RPM are the only values used in that calculation.

Ahh, nothing like being around the Evo community and feeling like a newb


But I am learning, because if I can modify my ROM without mucking things up anyone can
