  • AFR Lean kill switch ?????

    Anyone using the Dyno Tune lean AFR nitrous kill switch? Thinking of picking one up, just wondered if anyone has any experience with them... Not buying new, found a few used ones..

    Will also install a wideband in the spring..

    Sounds like a good idea. Basically what I get out of it is... If you're cruisin down the track and your car is running lean, it kills the N2O so you don't wreck the motor even more?

      are you still gonna have a standalone?
      sometimes you have to set them rather high to keep the lean spike with a fuel rail mounted from shutting it down

        Yep, I understand what it does.. I just wondered if anyone has one or knows someone, do they really work?

          Nope, no stand alone.. Sold it.. Is it worth the investment? Or a ***** to dial in since I will be running off the rail? Sorta sounds like it will cause more problems without a dedicated fuel system??

              Yep, not so sure, sounds like without a dedicated fuel system it may be a pain to dial in..

                  How would you know what to set the delay at?

                    Yes, lean NO2 is a very nasty display of sudden power discharge. I would think there's some kind of monitor that watched the gas flow to the nozzles and kills the nitro when there's a lean condition.

                      Just set the delay to something like a full second or even half a second. You need the delay because when the nitrous 1st hit you going to get a lean spike but thats only going to last a VERY short amount of time.

                          Got ya! So the lean spike is usually upon activation?

                          Keep me in mind.. Plan to relocate battery, could mount stand alone there..

                            ..
                            yes. since we have a regulator on the return line in the tank it doesn't respond very quickly to pressure changes.
                            you can run a shorter fuel line from the solenoid to the jet than the n20 line to help the spike

                              yes you could... i plan on keeping the nitrous set up itself to spray on the intercooler
