as soon as it changes from open loop to closed loop the combined ft goes to around 17% and the o2 isnt cycling. whats causing this?

Looks like it is entering closed loop, however, that 02 isn't cycling correctly. I haven't toyed with this a lot, but under Ecu Direct Access in the Load Scale section, you're still set as a 2.0.

Anyhow, check your wiring and the plug. What brand 02 sensor are you using and how do you have it wired?

Do you have the wire your o2 or oem plug o2? Anyho switch out the o2 after checking the wiring if that not the problem

i replaced the front o2, its cycling now, but the airflow per rev is at .35, for stroker its supposed to be .27 and the combined ft is 16.8% so they need adjusted.
