Nice.

Have you looked into the bargraph displays that have 5 greens, 3 yellows, and 2 reds?

Any progress with the digit displays?

[sticksdaman]

Any plans for the oil psi, oil temp gauges?

Those gauges are sick!

Have you tried the plastic mold making method or are you still sanding and polishing the stock ones?

[nando]

those look reaaaaly nice - a combo of vacuum/wideband would be pretty sweet. can you make them in distinct colors (like green for vacuum red for AFR) or are they already made? what switches do you need for cores?

[bmwpower]

Cool!

I guess these should work in an E28 as well since they share those style switches.

[eyagel]

nice george. i might be picking up a oil pressure if you ever get one or a volt

[T Verdier]

i will buy oil guages if you make them

[Stephen]

Wow, really cool. Maybe i missed it, but how complicated is install?

[alpinaclone]

With those videos George, you are going to give Billy Mays a run for his money.

I'll be down for a couple of those after I recover from the financial hemorrhage that my car has already caused.

[MR 325]

Looking good George!

great stuff george.

cant wait to have a few extra dollars to burn.

screw gift cards for christmas.

These look just awesome. I will definitely be getting one of these soon, just need to decide which one. I've already got both a wideband gauge and a boost gauge, but I would definitely like to have something like this as well.

If you could do oil pressure or oil temp, that would be awesome. That's what I really need. Any plans for something like that?

[gearheadE30]

All I really need right now are oil temp and pressure; any plans for those? Sadly, my M42 won't be seeing boost anytime soon.

This is by far one of the coolest things EVER. If my turbo car was a street/sleeper car, I would grab them.

I will probably still get them for the 318iS, just for sh*ts and giggles of it. How difficult is the installation?

[george graves]

How difficult is the installation?

Super simple. Pop out a blank and pop this in.

Boost - Power, ground, and a vacuum
Volt - Power, ground
Wideband - power, ground, and a single wire to your wideband controler.
Narrow band - Power ground and tap into the stock O2 sensor wiring. No need to install a second O2 sensor or weld a bung or anything.

Nice. Have you looked into the bargraph displays that have 5 greens, 3 yellows, and 2 reds?

The reason the led's are all one color has to do with the button. The light that is normally behind it is a standard incandescent type bulb that puts out "white" light. The buttons are very deeply tinted to filter that "white" light into the color of the gauge. So, putting green leds behind a red filter gives you almost no light at all. So yea, the button acts as a filter, blocking light not on it's "wavelength".

I think I'll work on the econometer gauge next.

All I really need right now are oil temp and pressure; any plans for those? Sadly, my M42 won't be seeing boost anytime soon.

Eventually.

Could you adjust the gauge before I bought it? (If I bought one)
