Wideband O2 tuning

I didn't find anything on the search. I'm wondering if anyone is using a wideband O2 to tune there bikes after installing a programmer. I have experience with stand alone fuel injection units on cars and will use a wideband to help driveability after a good initial tune on the dyno. I was thinking about doing it on my 2004 VFR with a PCIIIusb to not only help with power, but also gas mileage at certain throttle/rpm settings. The only thing the cars have over the bikes is I get to take my laptop along with the cars and tune on the fly. Thanks

 

I had great luck tuning my bike with the Wideband Commander. I recently bought the Dynojet LCD screen to further help with the tuning, and can't wait to try it.

My bike being a '98 and w/o O2 sensors, I simply welded a bung into the exhaust, wired it up, and it's worked great ever since. Plus, the Autometer gauge is great. The only negatives with it are a slightly limited recording time (15 mins) and the playback software is terrible. After each run, I would end up exporting the data from the Dynojet software and importing it into Excel, where I was able to overlay the recorded data on top of one another, and then quickly make changes to the PC map.

Also, if you go the Dynojet route, you can expand the datalogging power with the LCD screen and multi function hub (to connect up to the Wideband Commander and any other sensors you want), which allows you to add your own SD card for unlimited storage capability, and select from multiple maps on the fly.

 

How much do those add-ons cost?

 

I found my Wideband Commander for $370 last year, but it looks like they've gone up since then. The LCD display can be found for $260, and the multi-function hub runs $120.

If you want a portable unit to put on multiple bikes, and to be used just for datalogging, the Innovate Motorsports LM-1 is a pretty good deal at $430.

Zeitronix also has some nice, affordable products for datalogging and displaying Wideband readings. Another affordable unit is the Daytona WEGO.

 

Toro1 thanks for the reply, I can't believe your the only one who has been doing this:unsure:. Let me know how the Dynojet LCD screen works out. Definately need to shop around when it comes to wideband sensors and data loggers. There are some new players on the market with what looked like some great widebands and data loggers at this years SEMA show. I'd really like to try power commanders new LCD touch screen for tuning on the fly but just can't justify it at the moment.
