I recently purchased a Zietronics wideband kit with the Display box and I want to wire it to the tach signal but I know that it only reads half actual RPMs on a traditional tachometer.

How can I get around it? can I change the settings to make it read a 2 cylinder instead of a 4 to get correct RPM? If I do that and it works will it throw off the a/f reading?

I'm not exactly sure, but i'm willing to bet you need a TACH ADAPTER. Hopefully someone can chime in and say for sure.
