Does anybody have information on how to fine tune z-chip maps?

I want to learn to adjust my AFR after logging with the Zt-2. I want to know if lowering the numbers in the left bottom table, cause leaner AFR in the correlating RPM ranges. I have some minor adjustments to make to my map, but I am just generally interested to learn about this.

 

no idea, id give ttp a call tomorrow.

 

Positive numbers are more fuel, negative numbers take away fuel.

 

Thank you, that was my assumption. So when would I adjust the other table and how? Or do I leave it alone?

 

you don't finetune it

 

The other one is more complicated and is based on map voltage. It would probably be best to leave that one alone.

 

thank you very much for the info.
