I cannot get my maf histogram to read anthing but zero. Can someone give me some help on what to fix. I have tried everything I could find on that subject and it still just reads zero. Thank fo any help.

For normal readings, the plot value sensor is LTFT. The units are % and I set the hits to 3. The primary column row and axis should be set to MAF airflow vs output frequency. The secondary is MAF sensor frequency.

I also have a few custom ones I watch such as off idle and AFR error high. To get it to read off idle (so that decel doesn't throw your readings off) I add the filter [SENS.90] > 0, but use a different histogram for that.

You can mess around with different PIDs to tailor to suit your needs.

If you are going to filter out different situations for tuning like this it would be much more effective to filter on fuel cell instead of throttle position.

Thanks for the replys guys. Would it make a difference that I'm using a LQ4 MAF sensor. My laptop crashed so l had gotten a different one and downloaded the files from hp tuners website. The maf histogram is the only giving me problems.
