Time for a little video?

Youtube version:


Currently I have it set up for a narrow-band o2 gauge. Not the sexiest thing, but it was the easiest thing to do at first.. Nando is sending me a boost sensor (2 bar MAP sensor - thanks man!). But next, I'll modify if for wideband (LC-1 input) or volt-meter I think.

You can say what you want about a narrow band O2 gauge - I know this will spark up debate, but it's acutally a very "fun" gauge, it doesn't tell you much - but you can kinda see what your motor is doing. To me that's cool. That, and I think I could actually tell that my injectors *might* not be flowing enough - but who knows - it's only a narrow band!!! A wide band would tell me for sure.

I had to make a mount for the camera, and then placed the gauge in front of it on a little holder I made. It was either that or have a shaky video.

The brightness seems quite good. I'll try it out in sunlight tomorrow. The sun had just set in the video.

I think that would drive me crazy? Its so sporadic. You're definitely almost there though, keep it up, I love the stealth look of it.

If I wasn't going into an epileptic fit or if my eyes weren't watery from laughing at the Knightrider car motif....


But seriously George, it's very nice work, and well executed.
I like the attention to detail.

Cheers,
Chris

OMG Like Is said in the youtube comment:

"OMFG I love this. I want to buy one! This is great."

This is seriously some great work. I love how I was first afraid that I would not find much information on my e30 when I first got it. Now I see some crazy ass shit everyday. Great job.
