General 2g MAF airflow logger reading question?

[chanley talon]

Alright on my logger i hit 1606 hz at full open throttle and no more through out the entire driving range. My boost is set at 15 psi . And it has no knock . Im running a small 16g .
I put the logger on my bro in laws cars and it logs the same thing . He has a evo 3 16g and is running 20 psi and no knock and he flows the same air hz as i do 1606 . He is running a 2 g mas maf as well. So are we maxing out the airflow capability on a 2 gmaf?
What is normal hz readings ? How high can it go on a 2 gmaf unhacked 3 inch inlet pipe to turbo?

1606hz is just the limit that a 1G datalogger can Display.

Also I've hit about 2750hz on my unhacked 2g MAS with a 3" intake.

Oh i see how do i get around that? I guess there not alot of tunning i can do there.

Since you can see knock tune for that...not Hz count.

Tyler is absolutely correct. Also, I still haven't found a linear correlation between the MAS Hz count and actual air mass. So you can't get much useable information out of the Hz count. Just don't log that parameter and you'll get some additional samples / sec out of the logger.

I have seen 2900hz on a stock 2g mas.

you can use a eprom with div the Hz output for the logger, so if it shows "1000HZ" it means 2000Hz and so on.

Yes that is an option for the 1g chips.
