I'm looking for a wideband O2 system, would like to have 2 O2 sensors and a gauge or two to monitor front and rear cyl. Would be nice if the controller could produce a narrow band signal to feed the ecm. I've seen a few systems and don't know which one would be best. Anybody researched or used one on their bike, and how did you like it? | ||

I use a system from Innovate on my turbo race car and on my street beast. Very powerful system with good software. I don't remember if it can do narrow band though. http://www.innovatemotorsports.com/ | ||

Thanks for the link, I'll take a look! | ||

We use the same system from Innovative to street tune the Drummer line of mufflers. | ||

I have the Zeitronix, good unit with narrowband output. The 1125r does not like the simulated narrowband output from this or the LM1. These are great for tuning though. | ||

Thanks Xb9, I was afraid that the simulated narrowband would not jive with the ecm. I guess I'll just weld in extra bungs. I'm just trying to get everything together for tuning. Thanks again! | ||

Unless you can do cylinder trimming, you won't need to weld 2 bungs. Just put 1 after the collector. Trimming would allow you to change the fueling individually for each cylinder. | ||

This ecu HAS individual maps for front and rear cylinders. Individual o2 monitoring IS critical on tuning the 11...or any other engine for that matter. | ||

Trimming can be useful if you have a problematic engine such as a turbo inline 6 where cyl's 5 and 6 tend to run leaner than the fronts. Only race teams and OEs run individual EGTs or 02s during testing (too many cylinders, too much money). It' not even possible for most cars to do trimming as the ECU does not do individual trimming. My after market EMS does, but that's another story. If you're only dealing with only 2 cylinders, it is much easier to accomplish and to justify the expense. | ||

Chevycummins, use the existing bungs as you won't be tuning with the stock O2 feedback to the ECM. Unless you really want to drive your bike and yourself crazy. | ||

Htekwo, Last time I checked, most of us here run individual cylinder feedback as that is the only correct way to tune a multi cylinder engine. PM Easyrider and Xb9. They might afford a little more understanding to what your thinking. Best of luck in test and tune!  | ||

Xb9, I still haven't made up my mind on what I want to remap. I was thinking of just doing open loop rpm range. I thought it might be easier that way to get more power up high and still have good drivability at lower speeds. I still have a slight surge even after the last flash but am ok with it. I think I'm just a little too picky. I also thought that just doing open loop would be a little easier because I won't effect AFV that way, I wanted to keep the O2 sensors at this time. I have a crazy idea of a turbo 25R in the future and need to check into the turbo that I have to see if it is the correct size for this engine. This kind of stuff always gets me in trouble! |
