What formula are you using? Try (x*9/923)+10
If it doesn't work use only "x" and make a table relating the logged values with the values shown in the gauge. For example, 480 for 14.7 AFR. You can do it with engine off, so the reading would be stable.

Yes, you can change, but I believe it will give you wrong results.
Your formula should work, perhaps with some offset value. Log only X in Evoscan, 1 byte, with engine off but ACC on. Let your engine idle for a few minutes before you start the log, wait until everything is warmed up. When you turn off the engine, your AFR gauge should be reading something around 14.7, then it will lean a bit. Everytime the gauge changes, check the variation in X logs. Post it here when you finish.
Exemple:
14.7 = 120
14.9 = 125
15 = 127
15.1 = 130

Excellent, I'll give that a show this weekend and see what I can come up with. Thanks for your help with this
