I've been logging for quite a while now and the ben maps in the 400rpm row and 35 and 40 kPa columns are consistently lean (1.01to 1.04). THis lean scan is occuring after pasting and multiplying the cells against the previous VE table. It doesnt make any sense that the scan which follows is not showing a value which is more in the rich direction for these cols/row.


Is there something else in the tune file which is affecting the VE table values at engine idle? Throttle cracker..etc?

The rich -10 STFTs are only occuring during idle.
