My CanScan told me that from ~6600-7500 I am running around 12.5-12.7.

I cut more fuel in my CZ maps, then on the subsequent runs it looks like I am running RICHER.

The temperatures & etc. are all the same.

Is the ECU buggering me?

 

How did you cut fuel? Did you make the # bigger or smaller? ie from 40-42..or from 40-38?? The first will be leaner.....the second will be richer

 

Yes, numerically larger. I believe that number represents a % of fuel trimmed, so I went from '40-42'.

 

Reset , and then do three runs....average the values to see trends..and go from there :D

 

By restting the ecu, you will clear your LTFT reading.
