[QUOTE="keith89, post: 16290557, member: 53797"] the rear o2 sensors on my tune were previously shut down in the sct tune. I have since converted to the quarterhorse. The car is an 04 GT has cats and i have replaced all 4 oxygen sensors since they were the originals at 95k miles. I want to make sure i turn everything back on needed to set the catalyst monitor. So far i have changed to: HEGO - Rear > Downstreat Rear HEGO Heater (1&2): 1 HEGO - Rear > Rear HEGO Sensor Input: DUAL BANK Emissions - Catalyst Monitor > Catalytic Converter Temperature Input: Enab led The only other things I have noticed different from a stock tune are: Emissions - Catalyst Montior > Different Temp Average for Ambient and ACT: 40 insetead of 8 Emissions - Catalyst Montior > Fan Control ACT Delta to Resume Changing: 10 instead of 2 Is there anything else I should check? Also does the Evap monitor need to complete before the Catalyst? The Catalyst and Evap monitors are taking a while to set. I fixed a leak in the evap line last week and have driven 60 miles since(i probably need to do 1 or 2 more cold cycles). All the monitors on my Cobra set within 20 miles. I'm thinking it may be because the GT is an auto. Even the o2 sensor, heaters, and egr took quite a bit of time to set on the GT. [/QUOTE]
