So I was doing some searches on the Kpro while deciding which EMS to go with and stumbled upon a few issues that haven't really been widely acknowledged. I figured I'd start a thread listing issues/bugs that you guys have encountered with the Kpro so that prospective buyers can be more aware of what they are purchasing.

So far, I've seen the following things (can anyone confirm or deny?):

- coolant temp gauge is buggy, may operate in reverse (can anyone elaborate?)
- random CELs pertaining to o2 sensor?

Please feel free to add to the list..

 

temp gauge: sometimes takes up to 5 seconds before it displays the correct number of bars (not a big issue)
Randon CELs: no

 

I can agree with this post. Ive recently upgraded to K-Pro from AEM EMS, and the coolant temp doesn't respond right away, takes a few seconds (definatly less than 10 seconds).

Other than that, no issues or complaints about K-Pro, and I do not miss all of the stupid issues with EMS
