I've heard there's a revised one with dual oxygen sensors? Is there some sort of upgrade kit for the older one? I've got the single o2 sensor one, and want to upgrade to the 2 sensor one...do I have to buy a whole new A/F amp meter, or is the original one upgradable? Anyone know?

 

The first AFK only had option for 1 o2 sensor. The newer AFK has option for 2 o2 sensors. As far as your cel, I'm confused. At least in the way I have mine installed, the factory 02 sensors stayed in place. New bungs were made for the AFK o2 sensors.

no, there is no upgrade. sucks too, cause i like the way the older knockamp looks over the new one.

 

You will have to buy the newer AFK. Here is a pic of mine.

I don't like the new one either.... I like the display of the old one...... Me like colors
