Dynotune lean shut-down switch Does anyone have any experience with their new shut-down switch yet? I'm debating of I should get one or not. The price is cheap enough for what it proclaims to do. I just want to get some real world feedback from people that have used them already.
The switch is in production in volume now. Our manufacturer is slower than we would like. All the preliminary units we tested worked exactly as stated. We just need to get them in house!

The switch should work on any car, bike or truck.
The switch utilizes narrow band or wideband your choice. Narrow band jumps around at anything beyond wide open throttle. But you are typically spraying at WOT so you will get a steady reading. With the price of widebands today -or our Innovate pricing anyway, wideband is the way to go.

I installed a A/F guage to go with my dynotune kit..
It is hooked up to the front driver side oxy sen.... and yes they do jump around, they are running on a 12 volt signal, but even with the jumping around.
If you somewhat understand what you are looking at. Then you can get a good enough reading off of it...
Mine is a light show, but my tune has my car rich @ WOT, so I see the blue lights flickering alot.... But when I am hitting the N2O at WOT..
It stays dam steady...
Alot more steady then anyone was telling me....
Even my buddy seen it and said wow that dont work too bad....
He runs a wide band.
With your normal A/F gauge, as long as it's pretty much in synch with the wideband dyno A/F (when your car is tuned on the dyno for nitrous), I would think the gauge would be safe to go by and would be pretty accurate going forward. But, a lean shutdown switch for such a small price would be well worth it if your A/F gauge ever failed on you. Anything can and will happen when you least expect it. The only reason I haven't bought one for my new kit is becasue the website always says they are 'Out of Stock'.

We took it off as we were getting tons of phone calls on it as well as crazy amounts of emails. We spoke with our manufacturer last week and things are coming along. We will put it back up when we have them in hand. We know they are in process so were hopeing! Looks like we will also be adding a few more sweet features!

yes. its a basic control circuit. just like a fuel pressure safety switch. it takes a splice off the 02 sensor and if it sees lean for more then a certain ammount of time, it will open the circuit and stop the nitrous.
myfast70 - That is our plan 
CETA_TransAm - Yes shutting the system down when it goes lean is one of its features - it is microprocesser controlled so we have added quite a bit of intelligence and functionality to it.
Just need to get them out of our manufacturing facility and in our hands
