MAF Frequency (Hz)
 

I want to log my MAF sensor frequency (Hz).

I know that the Aeroforce Interceptor gauge does this, but what else could I use?
I don't want to have to buy a gauge just for this.

I am using:
- ELM 327 cable (hardware)
- OBD 2007 (free software, http://www.glmsoftware.com/)

I want to get my MAF tuned; my long term fuel trims are at +29.1% at idle !!

So far I got a log of my LTFT along with engine RPM and MAF Air Flow in grams/sec. All I'm missing is the frequency log, but the software I'm using doesn't do this.

thanks guys

I'm trying to do it myself...

Otherwise I simply would have asked for someone with HP Tuners or an Interceptor Gauge.... which is what I might end up doing

Paying for logging your MAF frequency is kind of a rip off IMO

Pls Hold.

Logs up to 4 Parameters at once.

You can complain all you want but HPTuners is kinda necessary if you want to tune the MAF. Might as well make it easy on yourself and log with it too.

Maf frequency is a enhanced GM pid similar to knock retard, you'll be hardpressed to find anything free to do what you want in this case.

the DashHawk logs all of that up to five parameters are any give time. I could log mine if that would help for some reason.
