I know DynoTune makes a Lean Shutdown Switch, Does anyone make a lean-rich shutdown switch? OR Is there a way to use a wideband gauge or controler to do the same?

 

Don't you have the HW stuff? I think their MicroEDGE has that feature.

"A/F Shut Down Switch: Nitrous system(s) will shut down if a lean condition is detected by either a wideband O2 sensor or narrowband O2 sensor. The MicroEdge+ will also shut down the system if an overly rich A/F is detected (wideband sensor only)."

As an alternative you can just get a FPSS(Fuel Pressure Safety Switch) if you are running a wet kit. If your fuel pressure drops too low(whatever you set it too) it will shut off the nitrous. It costs between $35-50 depending on which one you need.

BTW, could you help me finish up the wiring on my nitrous kit?

 

Already running a fuel pressure safety switch, I already have a FPSS, but I was looking at other options as well. Yeah I have an HSW kit but I'm not very happy with their customer service. Remember the microedge has that feature just wondering if anyone else has something similar.

Where are you located?

 

I have the Nitrous Outlet Digital Progressive Controller and just looked and it also comes with a "lean cut off feature".

They have excellent customer service and are a vendor here as well.

I live in the IE but can drive to where you are at and you can help me wire the progressive.

 

I have a Wide Open Throttle/RPM Window Switch from Nitrous Outlet and they have great customer service. I am probably going to make the switch to them. Right now I don't have any of my system in because I had an issure with a purge solenoid. Going to move some stuff around and re route some wiring. I don't have a whole lot of room to work right now, but if you do, I can come help you out.

 

If you haven't used the window switch yet you may be able to exchange it for the progressive controller and just pay the difference.


I have plenty of room in my driveway and/or garage.

 

Well it was already hooked up so that's out. I was looking at the DynoTune Lean Cut out Switch but I'd like to have a rich cut out too.

Cool I may have some time next weekend. Just wondering, have I seen your truck at Irwindale? There was a truck there that looked like the one in your sig, but I think it had some orange decals on it.

 

Yeh , that was probably me. It came with factory Red(Orangy) 400SS stickers on it.

 

Oh ok cool. You have a pretty nice truck from what I remember of it.

 

Anyone have any more info on this?
