Default MPH activation switch

Is there any switches out there that can turn on or off base upon the MPH? I'm looking for one of these to use with my nitrous second stage.

Thanks. :cheers:

I don't think so. Just buy a second window switch for stage two :D

Yeah...but with a second rpm switch, it will still go off in the first few gears. I only want the second stage to go off at 60mph or higher.

Hmmm...I will have to dig around the service manuals tonight and see if there is any wire we can tap into. :crazy: :crazy: :crazy:

What gear would you want to be spraying in? You have to be careful with a MPH activate control because if your desired MPH of activation in an certain gear is below 2500 RPM then you're asking for big big trouble in your motor.

The MPH switch will sit in series, after all the other switches (RPM, TPS and FPSS). So unless all other switches are on, it will not get activated.

Ok, I see how you're wired up now. What about, if you wanted to spray in 3rd at 60MPH you wired up an activation switch in your shifter gate so that when you put the car in 3rd it activates the window switch at the RPM responsible for 60MPH :)

Very cool idea Tuan. I would be interested in such a switch :yesnod:

There was a recent post with pics showing how someone did this...I believe it was in the FI section. He siliconed the switch to the shifter boot.

I see that you've already seen the arrangement I mentioned, Tuan. Here the post ID again if you wanna check it out again: http://forums.corvetteforum.com/zerothread?id=342472.

What you want is the same as an RPM window switch but will monitor the speedo signal coming from the diff. That would be cool

Yeah...But as soon as you shift out of 3rd, the second stage will get cut off.

Yup, that is exactly what I wanted. I can't believe no one has bother to come up with a switch like this. It would work wonder, in addition to your rpm window switch.

Hell, even if you only have one stage, it would be great too. Forget the freaking expensive progressive controller. Just have your 100 or 150shot go off at ~60mph and you're set.:D

Nahh.....I'll stick with just one MPH activation switch. But the problem is that there isn't one out there.:lol:

Well, it's time to bring out the dusty service manuals.:D
