dailing in fuel

[Bonk1070]

trying to get my fuel dialed in my idle afr is 17.0 to 19.0 once on the throttle up to cruise it runs 14.0 to 15.2 once at cruse goes back lean not sure were to make changes also I see the o2 sensors don't move very much is this normal

log idle to cruise.xdl

no it looks like your o2 sensors are shut off. There is an o2 sensor enable/disable switch from the ecu that is used as a ground reference. It should be near the back of the cylinder head its usually an o-ring and is the hego ground wire. Make sure that wire is hooked up to either the head or a good ground. If you can't find that wire then you will have to jump the ecu wire off at the ecu connector to enable the hegos.

its not wise to go WOT until you have your fuel dialed in

I checked my o2 plug wiring have switched 12v good ground and pins 29,43 ohm good to the ecm not sure why they are not turned on
