I have a Iso-com and an 02TT. What block or blocks do I have to log and are there calculations if any ?
Thanks for the support

Look in block 217. There you can see O2 voltage and EGT in C°. The voltage is between 1 and 0. 1v is the same as an A/F ratio of 14,7:1. With that you can calculate the other values. Do a full throttle run from 2000 to 6500rpm.

So you can get a sense of if the car is running generally rich or lean. At WOT it relies more on fuel maps and not O2 sensors.
