Sup guys.
I pretty much tune my car pretty good (under no boost)
But I am wondering.
I try to set the fuel map to be a bit richer. so it will be around 13.5:1 instead of 14.7:1

But whenever I turn on the EGO Control under Basic Setting->exhaust gas setting. if I set EGO to be active above certain coolant temp and RPM. then when EGO is active, it will fix the AFR to around 14.7:1. Then when I wanna accelerate a bit faster, the EGT will rise alot faster now since it will stay around 14-15:1 for AFR.

But if I turn off the EGO control (like setting the active above RPM to 5000RPM). Then without EGO control, and with VE table a bit richer, the EGT stay around 1400-1500F during regular driving. because now without EGO control, my AFR shown in my WBo2 will be around 13.x:1 during load.

So if this is the case, what is the point of the EGO? can I setup the EGO control so it will correct the AFR to like 13.7:1 instead of 14.7:1??

Also, what is the best AFR during idling, below boosting (regular driving), and under boost?

Thanks guys!
Gilbert
