Nlucc Posted December 16, 2017 Share Posted December 16, 2017 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 Link to comment Share on other sites More sharing options...

Beemer Posted December 17, 2017 Share Posted December 17, 2017 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. Beemer Link to comment Share on other sites More sharing options...
superfishal Posted December 17, 2017 Share Posted December 17, 2017 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. Link to comment Share on other sites More sharing options...
Nlucc Posted December 18, 2017 Author Share Posted December 18, 2017 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 Link to comment Share on other sites More sharing options...

Sorry for reviving this but a 02 eliminator wont make the bike in a closed loop anyway because the o2 is mimicking a real o2 sensor? Link to comment Share on other sites More sharing options...
