I did a google search on google and then the google search on here but still don't see a Air Fuel gage that will work with leaded fuel other than the one Holley makes and puts either Holley, MSD or NOS stickers on it. Its the only one Ive seen saying it works with leaded fuel. Zeirtronix says they don't make one and just change the sensor as needed. What are you folks using?

They all work with leaded fuel, they just don't work very long. The lead pollutes the sensor and they start to read wacky after a few hours of use. On the race car the sensor gets changed every season. On the dyno the sensors get changed when they start to read funny which typically is every 20 engines or so.

I installed an lm-2 system in the race car. Needs calibration out of the collector before each time out . records on a chip to use with a lap top. replacement sensors will costs $90 to keep a spare. Certainly worth having .

I ran the same Oxy sensor for many years w/a mix of leaded and pump gas and sometimes straight leaded gas and it was fine but now I run VP-101 unleaded and I have a few years on the new sensor with solid 02 readings from idle to 7000 r's.......
