I just thought of a new use for those annoying service interval LEDs.

Has anyone ever seen an e30 with the service interval LEDs converted into a bar graph rev counter with a shift light?

I wanted try this on my 318is and I was wondering if anybody has accomplished this before.

I've seen write ups for O2 sensors...that was my thought. They're pretty useless now...but were so cool in 1987!

i tried the o2 one and couldn't get it to work. thought it would be cool for the o2 but not so cool for the rpm gauge. i had it in an 85 300zx and it was cool on that. very knight rider
