Using a wideband with a Stinger

[bigaaron]

The lsm-11 was the best sensor available at the time, and has been used in motorsports for years. Motec even used it at some point.

Keep in mind that you don't have to have a wideband connected to the Stinger unless you want to run closed loop. If you already have a Zeitronix or something else with a display, you can use that for tuning. It just makes it convienent to have one connected to the Stinger so you can log with the standalone.

Here is a spec sheet on it:

If you use a wideband plugged into the Stinger can't you also use the "tune analyzer" feature wich will actually make it's own map? Quoted from the stinger manual page 68

"You can have the system automatically adjust the fuel map if you want. First you must set the target AF ratio for each load point Press the Target AF Ratio tab and enter the target AF ratio for each load point you want adjusted. You can also move the actual AF Readings over to the Target map by pressing the Actual to Target button and then adjust each load point to the desired value. Any load point with a 0 (zero) target value will not be adjusted. Press the Apply Changes button. The system will compare the actual AF ratios with the target ones and adjust the fuel map accordingly."

yea, I've used that feature it's great for cruising, but I don't use it for WOT tuning.

Why is that?

 

[hottscennessey]

I like the old fashioned way better, I like to watch the AFR's in real-time rather than have the computer record them.

when cruise tuning it just takes the average so it's perfect.

They are a lean burn sensor?
What will they go down to? i.e. will they go down to 10-11:1?

 

[bigaaron]

I believe the lSM-11 sensor will be accurate down to 10:1, and up to 20:1.
The LC-1 will go from 8:1 to 22:1, and it needs to be calibrated as described in the Stinger help file which comes with the free download Stinger software.
