How do I get my speedo to work on my k24a2 eg? Also the car currently only has a wide and o2 running on hondata. Do I need to add the primary o2 sensor also?

 

What transmission are you using ?

 

k20z3

 

You will need a speedo healer (conversion box to change a high frequency signal to a low frequency signal). K-Tuned, Dakota Digital and Modifry all offer options. You will wire this device into the engine harness near the ECU to make things work.

 

I had a stock o2 sensor and it was displayed in Kpro which was nice!.

You can use either one, the wideband or stock O2.

 

I meant I have a aem wideband gauge, do I need the primary o2 also hooked up

 

No
