[Diy_efi] Flap-type Airflow Meters

[ScottyGrover at aol.com]

Dan was asking about these Bosch/Nippon meters and how they were  calibrated. 
I put 12VDC between pins 6 and 9 and hooked a voltmeter between pins  6 and 
7. I then rotated the toothed wheel on the end of the rotating shaft and  this 
is what I read:
Base       1.29V
1 tooth     1.75V
2 teeth     2.7V
3    "        4.3V
4    "        5.3V
5     "       5.9V
6     "       6.5V
7     "       6.8V
8     "       7.3V
9     "       7.6V
10   "       7.95V
11   "       8.05V
12   "       8.2V
max         8.21V
 
I hope this helps.
