Question What to use to display A/F ratio's?

My car is tuned with a SAFC II with buschur settings. I am under the understanding that obviously the SAFC is used to adjust A/F ratio's, but can it be used display what your A/F ratio is? If so, I do not know how to find it on the SAFC. Or do I need to use a scan tool to get the ratio? I was looking into getting a pocketlogger. Does this tool work well for displaying A/F ratio's?

well it wont display the a/f ratio because of the sensor select option......since its karman it wont work but i have a little secret....... .....just tap your in2 wire to the 02 sensor signal wire on the computer and your get the voltage reads of the sensor.....which is better that a a/f guage to my understanding this is the pretty close conversion that i got...


Volts A/F ratio

.1 --- 17:1
.2 --- 16.5
.3 --- 16:1
.4 --- 15.4
.5 --- 14.9
.6 --- 14.4
.7 --- 13.8
.8 --- 13.2
.9 --- 12.7
.985 --- 12.1



Enjoy

These are close but do not use them for WOT operations. The Stock O2 is just not good enough. You need a true wideband setup. Like the FJO.

Also those numbers up there are to far apart. If your car jumps from .9 to .7 at WOT then it could be bye bye engine. So do not use them. SSkiller is on the right track but you need more percise numbers.
