Recommended Posts

Hi.. I have a 2017 fz-07 and just installed an akrapovic carbon exhaust along with an EJK controller. Installed everything as described, disconnected the o2 sensor and when started the bike a got a check engine light with no codes. Bike runs fine, checked everything, no clue.. 

 

Any ideas?? 

Thanks

I was told the EJK overrides the 02 sensor from 1500 rpm on up so maybe a problem with the EJK itself. What Cruizin said.

Same happened to me with same exact setup on my 2015 and I talked to dobeck customer service and they never got back to me with a solution(possibly because I'm in California and the ejk is not exactly road legal in this state) so I switched to the power commander. It's not perfect but got me power gains where I wanted them ( 1st gear slow speeds is a little jerky but manageable). I don't know if it was a faulty ejk or what but at least now I know I wasn't the only one with that issue. Good luck solving the problem.

Thanks for the responses. 

Took it to the dealer and the light was for o2 sensor disconnected. If I reconnect it the light goes off.. So either live with the lights,  leave it connected or flash the ecu 

 

Let's see how the bike feels with the o2

You can buy lambda (O2) sensor eliminator kit off ebay, it will stop the check engine light.
