After a recent engine bay wash and hours of trouble shooting to figure out why in the world my Tach wasnt working any more, I found that a fair amount of water had gotten into my Summit RPM Switch. Once I took it apart I quickly realized the weak points of the enclosure design. There is no gasket for the lid and a gapping area where the wires come out. To save myself this problem in the future I decided to make a quick trip to Fry's Electronics and engineer a better enclosure. This is what I came up with.

When does your open? IIRC, your last dyno showed no such event.

Dubbya

3800 RPM. It does open. Visually verified many times. The switch has been on there since day 1.

Must be the lack of VTC's for the lack of low-end'ness

Lack of EU doesnt help either

kinda ot.. but how did you get your rpm switch to open then close again?

Dubbya

iTrader: (16)

It only activates at 3800 RPM and above so as soon as RPM's are below the threshold it closes.

If you mean how did I physically open the RPM switch, there are 4 screws.

IMO, the open/closing of the 2k2 VIAS is negligible. Activating it anywhere from 3600 - 3800 would be fine.

why not just install it in under the dash? mine is under the shifter trim.

Mine is next to my left foot, just above the dead pedal region.

i'm in the process of installing my 00vi,
1) do i need to buy a RPM switch?
2) and if i block off the EGR do i still need an 00 EGR tube guide
3) where would i get block off plates for my swirl valves
4) do i need a new PCV valve

Only problem with that 'mod' - now the summit rpm switch is even BIGGER - surprised they used such a large enclosure in the first place.

Id rather have it bigger than wet again. I didnt install it in the first place, but I guess I could relocate it. I was bored and made a trip to Fry's. My over engineering got the best of me.

its better than the guy who used a ziploc/rubber maid container and posted pix here. that was ghetto as hell.

4100 hasnt been bad either... still yet to dyno.

Why not use the rtv to form a gasket on the original lid of the switch? and squirt some where the wires come out too?

Dubbya

iTrader: (16)

Because I felt like doing it this way.

NmexMAX

iTrader: (22)

I'm sure lack of CVTC is also a concern. So playing w/ different RPM points on a dyno sounds like a nice idea.

nice work but uner the radio/shifter trim makes for easy access

That would have been my solution. My RPM switch actually has an O ring type of gasket around its lid to seal it, the only area that could allow moisture in is where the wires come out of it. Silicone would solve that easily enough though.

Under the hood is just as easy. Plus having RCA wires and other wiring for other devices makes it a bit tight there too, at least for me.
In theory you could just mount it any where but for me under the hood was the easiest and fastest solution. No need to run a lot of wire to it.

There was no O-Ring on mine. Also this way allows me access with out having to cut through or redo any RTV should I need to open it back up.
