I'm installing a heated 3-wire o2 this weekend as a permanent replacement for my stock o2.

Has anyone done a compare of oxygen sensor .bin parameters for a vehicle with a stock heated o2 like a 93 LT1 Vette against a non-heated 90-92 L98/LB9???

I figure it would be most wise to simply copy what GM changed when they went from a non-heated o2 to a heated one.

Thanks!

In TunerPro I just compared a 1993 Vette LT1 to a 1992 F-Body TPI and these are the only o2 parameters I could find:

Constants:

Min Cool Temp for Closed Loop - -40.00 Deg C
Min Coolant Temp for BLM Update - 80.00 Deg C
Max Coolant Temp for BLM Update - 41.00 Deg C
Min MAP for BLM Update - 5.00 Kpa

Tables:

Open Loop %Change to Fuel/Air Ratio Vs. Coolant Temp
Open Loop %Change to Fuel/Air Ratio Vs. MAP

I thought there were more in the F-Body bin?

Any thoughts???

Here are some other o2 item addresses for 90-92 TPI.
The values may have more to do with the code operation that with sensor differences but worth looking into IMO.
