Dynojet wide band question

[nanookszy]

I was wondering if anyone was using a dyno jet wide band o2 on their cars? Also what should my readings be between for my ratio? I was thinking it should stay between 13 and 14. I just want to make sure before i go tuning my safc and gmaft.

umm, maybe for idle, but thats still a bit rich. Idle I keep at 14.7:1

for wide open throttle on pump gas,

DO NOT GO OVER 11:1 UNLESS YOU KNOW WHAT YOUR DOING AND YOUR WATCHING YOUR KNOCK SENSOR RELIGIOUSLY

most people use 10.5:1 and then tune their ignition timing so that its as agressive as possible until they get knock, then retard it by 2-3 degrees so they will make a decent amount of power and not have to worry about knocking too much.

for cruising over 1200 rpms, go for an afr of ~21:1 ( because you have a choice at that point)
