Air/Fuel Ratio "Lean shut down switch"
 

Just wondering if anyone is running this unit or knows of anyone running one (or something out there that's similar)......IMO, It looks pretty good for the price (if it works as advertised that is:cool:)............. http://www.dynotunenitrous.com/store...p?idproduct=67

If you're familiar with electronics, something like that would be easy to make minus all the bells and whistles. The low fuel pressure switch method might be a better way to go about it though.

Maybe I'll go down to my mad scientist lair and tinker with this next time we get some rain/lightening lol.

Yea, it may be worth it to some guys to mess with... build one up:cool:.....To me: It's like, Why bother to re-create something like that, minus half the features(IE: bells and whistles)...(probably end up spending close to the 99 bucks they get for it once I factored in my time, LOL).......I do know quite a bit about electronics ,and nitrous systems. (been building engines and setting up nitrous systems at a pretty high level for over 20 years).....I would NEVER consider completely replacing a FPSS with the device at this point in time....but to have "another" fail-safe in the system is always a good Idea in my book (as long as it works properly).......Just wondering if anyone has personally used it (or one just like it)??...........Joe:cool:

You can buy an adjustable Hobbs switch for ~$40.That's what I use.

:think:.......:lol:.......yea, me too....on "ALL" of my nitrous set-ups (current & past) for the last 20 plus years, LOL.....Not really my question though(thanks anyway)............Joe

If you hook it up to the stock narrow-band O2 sensor, it makes it a fairly crude device. The stock O2 sensors are simply nowhere near accurate at the A/F ratio you want for nitrous. They are extremely sensitive to temperature in that range, and a small difference in temperature will affect them more than a large change in A/F ratio.

If you have a wide-band sensor, its a much more reliable setup.
