Pulsewidth fluxuation

[Mirageman]

I think the pulsewidth is supposed to be a steady line on my pocketlogger. Mine is not. It looks more like a saw tooth going up and down between 61% and 79%, mostly in 3rd gear. However the other vital signs are OK. O2 is steady at .74, knock is O, timing is about 21, and the SAFC HZ reads a max of 1825 [the MAS is totally gutted].The car runs real strong. Am I getting a corrupted MAS signal from overflow? Is this abnormal and should I be concerned?

Kyle,
One of the nice features, besides tuning, of the AFC is airflow count of the MAS displayed as Hz. I think an upgrade would show a higher Hz #.
Anyway select the monitor, select Karman. This will give you a Hz #. If you want this to peak hold till the ign. goes off select the up arrow button or the down arrow to turn it off. This is neat because it shows the max. airflow # of the MAS during a drive, while you keep your eyes on the road.

2 things, how are you reading over 1606?? Thats as high as our loggers go??

And the other thing is I'd say .74 is way too lean.

Bohrn, you should read that I said the SAFC read over 1800, not the logger. O2 readings from a Pocketlogger are not the same as a monitor like a Jumptronics - .74 is about the same as .9 on a Jumptronics. You must have noticed that readings in the 7's are normal for a Pocketlogger, for whatever reason. This bothered me too until, Mike at pocketlogger, confirmed readings in the 7's.

I know how to set up the SAFC to do this.

I was asking you what the line looks like on your SAFC. Is it linear, smooth, rough, jumpy, nonexistant, etc...
