without a wideband, its all guesswork. there is no certain mV that corresponds to a certain AFR. any scanner/logger that people have used with a wideband will prove this.
not trying to be a jerk, but its very tough... thats what im getting at. you might want to invest in a wideband, you can pick up a plx from EDO performance(sponsor here, running a GP on them) that way there is no confusion and its a lot safer.

When you are running the nitrous you should be at wide open throttle and the narrow band will be steady at wot so will work well for shutting the nitrous down. A wideband is preferred as it can be used for tuning as well as it is steady throughout the rpm band hence the name wide band. If you want to go that route we are a warehouse distributor for Innovate and PLX and can help you out there. Give us a ring if you like we will talk you through settings for your application and give you a btter understanding! We are here to help!

I use the AEM wideband with the dynotune lean shutdown switch. I highly suggest you invest in a wideband setup for accuracy. I have it set at 12.5 a/f which is on the safe side. Havent had any problems...make sure you set the delay because it wont spray at all because of the lean spike. (thats just my experience)

call us for the best price on a LC-1 wideband controller as we give discounts to members.
The narrowband factory o2 sensors work fine if something serious happens to your system, say you use a competitors fuel solenoid and it sticks becasue your using race fuel.....The narrow band o2 sensor it plenty accurate to detect that lean problem! It will shut down the nitrous... .500 v = 14.7:1 if your fuel solenoid does not open it will run somewhere around here.......so if you set it to .700-.800v you should have plenty of room for saftey.... Hope this helps?

If I want to run the lean shutdown box off my narrow band sensors, which side of the sensor do I hook it up to, the high or low side? Blue29 is the wire I currently have it hook up to and it doesn't read worth a crap. I have a FAST WB unit. How do I set it up to work with the FAST output?
