my new instrument cluster...

Recommended Posts

what do you think about it ? its a E30 speedo, with a custom front end to look like the font/lettering of the 02...it is to go along with the 4HP22.

there is some details still to fix but i think i reached my goal. Even the trip reset button works.

there will be a tiny black box to convert the signal 6/8 from the half shaft bolts/proximity sensor, mounted very stealth above the diff. no huge ninja start there to send pulses to the sensor, plain and simple....

Very nice, where'd you get the custom lettering done.

I'm hoping to do something very similar, but with a silver dollar cluster and the e30 speedo (or maybe a modern VDO aftermarket piece if the electronics would work out easier).

i did it myself. i scaned both, the e30 and the 02 speedo plate, and worked out the lettering so i would fit on the e30 face.

the new speedo uses the same mounting point into the cluster. only the fixing point onthe the car itself(the two long studs that normaly gets out of the speedo) wont be there.

Why use a black box when the silver can does the converting internally?

what do you mean the silver ?? its an electronic speedo dude, it needs to read 8 pulses per revolution to be accurate.

since i dont want to use a huge star at the diff i decided to use the hlaf shaft bolts, and there is 6 so the signal needs to be converted. The speedo itself is not adjustable for 6 pulses.

Any chance you'd care to share the signal pickup details?

Since 320i transmissions are getting scarce around here, I'm pondering something from an e30 but the whole mechanical speedo issue has me temporarily halted. Photos of the bracket and sensor perhaps?

Thanks.

go there for details on the signal pick-up.

yep that was one of my concern, ie, almost original look.

yours is not bad either !!

fwiw, here is my .jpg of the sticker. print it on 1:1 or 4x7 and your are done. free.

Since I have negative talent in the electrical engineer department, I was thinking of making a tamer version of the scary looking pickup wheel and maybe having a local laser or edm shop burn one for me if my crude prototype worked. I could get it with six holes to match the axle bolts and nine (or however many) tabs to not have to do the electronic conversion and then use a bracket similar to what you made. In reading your project blog, you were converting to a 4 speed manual rather than a 5 speed?

i am converting the car from a 3 speed Automatic to a 4 speed Automatic.

the problem with the speedo itself is it needs to see a square wave signal, ie, evenly spaced highs and lows. If you dont then the speedo act waky. My black box reads the period and convert it back so the duty cycle is irrelevent. this is one beauty of the thing. the second one is since it read the speed at the half shaft, then i can play with diffs ratios wihtout any affect on the speedo. And third, there is a potentiometer on my black box if i ever run different diameter tires to fine tune the readout, ±20%.

hth.

I used a 120mph VDO electronic speedometer for the gauge and a $30 speed sensor for the sender:

Disadvantage of using the new VDO gauge: LCD odometer doesn't look stock.

Advantage of using the new VDO gauge: You can use a few different kinds of input (Hall Effect, VR sensor...) and you can recalibrate it in a matter of minutes if you change diff ratios or tire or wheel size. There's a setting that only requires that you drive exactly one mile and the speedometer figures it out from there. Pretty cool.

Hey,

Your silver dollar cluster looks great. That's exactly what I'm going for (and I don't care about the digital odometer). Any chance you could share some info on what all you had to do to get it work so nicely?

Thanks
