You can raize the Maz Fail High under the Airflow table in Engine Diagnostics. I don't know if it will help for your application or not but worth a try.

This is the IFR table from a Stage flash which uses 42s:
5.06006 5.10999 5.17004 5.21997 5.27002 5.31995 5.38000 5.43005 5.47998 5.54004 5.58997 5.64001 5.68994 5.75000 5.80005 5.84998 5.91003 5.95996 6.01001 6.06006 6.09998 6.15002 6.18994 6.22998 6.27002 6.31006 6.34998 6.40002 6.43994 6.48999 6.53003 6.56006 6.57996

I don't know why you are using 42lb injectors though!

How high can it be raised...it's over 12k now

Also, the ifr nuimbers are in or around the 40's, not 8

Thanks

The max you can go for the Maf fail freq is 16384hz.

And here's the IFR table in the unit your want:
40.16013 40.55638 41.03305 41.42930 41.82653 42.22278 42.69945 43.09667 43.49292 43.96959 44.36584 44.76306 45.15932 45.63598 46.03321 46.42946 46.90613 47.30238 47.69960 48.09682 48.41363 48.81085 49.12766 49.44544 49.76322 50.08100 50.39780 50.79503 51.11184 51.50906 51.82684 52.06517 52.22309
