S15 gauge cluster installed - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I just finnished making a siginal converter for the speedo and wired everything in my car last night. Everything works good, i even made the speedo read in mph not kph.

If there is any interest i can make a writeup with schematics on how to do it.

murda-c · 11-08-2007, 09:45 AM

or pix...........

spg240sx · 11-08-2007, 09:46 AM

definitely pics! I'd like to see it

240trainee · 11-08-2007, 09:48 AM

schematic would be cool, pictures of how you made it not fit like ass would be better.

Everyone knows its not a direct drop in, you have to cut your dash and bezel and mold everything back in.

I just havnt gotten to that part yet

koukimonster139 · 11-08-2007, 10:01 AM

damn that was really informative.

.......

xsparc · 11-08-2007, 10:12 AM

damn you people are harsh. now i remember why i stoped posting here

anyway here is the schematic

C2B 1U
C3 0.1U
C4 1U
C5 0.1U
C6 0.22U
C7 0.22U

R5 100K
R6 47
R7 6.8K
R8 10K
R9 6.8K
R10 5K Pot

:NOTE: R10 needs to be adjusted so that the resistance from IC4 pin 2 to GND is 11560 ohms, it may need to be adjusted more or less than this depending on the exact values of the other resistors.

Signal IN = 4.5hz/mph sine wave
Signal Out = 12.5hz/mph 0-5v square wave

If you look at the datasheets for the ICs (google) you can find the formulas on how all the parts interact.

Quigs · 11-08-2007, 10:53 AM

Interesting project. Cant wait to see it installed and finished. Looks like it will work out nice.

bryce with a y · 11-08-2007, 10:54 AM

haha i lol'ed when i saw this pic.

looks like legos...

importdude · 11-08-2007, 10:58 AM

nice job,
mabe u should goin the market of making premade boards for ppl on zil

xsparc · 11-08-2007, 10:59 AM

dont think i have enough parts here at work to do that

B Love · 11-08-2007, 01:36 PM

Whats the advantage to using s15 cluster? Or do you like the look better is that why you did it?

Bobafreak · 11-08-2007, 01:42 PM

I think thats pretty cool. Its very unique. Im not trying to sound like a smartass either. but looking at the schematics.....no thank you. lol

Laxman · 11-08-2007, 02:05 PM

Awesome writeup! Wish I could do the same.

I HAD an S15 cluster, till some dirtbag in SOCAL stole my shit.

Bobafreak · 11-08-2007, 02:07 PM

dont blame socal...blame his parents for not raising him/her right. lol

sideview_180sx · 11-08-2007, 02:13 PM

So did you get the mileage to read as well?? That is a very nice project you have underway. I'm rooting to see the complete finished product

that secmatic is super simple. look at the pic of the board. anyone with a couple of years in electronics experience could make this up for you in under 30 min tops with all the parts. and i bet most of those pars are easy to some by... am i wrong OP?

jackjack · 11-08-2007, 02:25 PM

lookin good. rock on.

240trainee · 11-08-2007, 02:32 PM

Thats fucking badass, that might be an option for my track car where dash fit and finish won't be as big a deal as a street car....

xsparc · 11-08-2007, 02:33 PM

yes it does read MPH even though the meter says KPH
so 20kph = 20mph and 100kph = 100mph and so on

speed sensor = 4.5hz/mph sine wave
s15 cluster input = 12.5hz/number on meter 0-5v square wave
s13 ecu speed input = 0.5hz/mph 0-5v square wave

designing the converter took about 3 days in my offtime at work but building it too maybe 1 hour. my hands are kinda shakey.

the parts are all basic stuff except for the lm2917 and the lm231. i had to order those.

JRas · 11-08-2007, 05:57 PM

very cool can't wait to see it installed in the dash.

xsparc · 11-08-2007, 06:29 PM

ok just got the temp gauge working correctly. a 200ohm resistor needs to be added somewhere between the gauge and the sensor. i put mine about an inch down the wire from the guage.

*brndck* · 11-08-2007, 07:25 PM

you sir, fuxking rock! glad to see someone doing something new and different!

Unit-121 · 11-08-2007, 07:37 PM

Im already liking it!. See how it turns out wen everything is intact.

11-11-2007, 01:18 PM

who wrote/made the schematics?

bRUt@L`S13 · 11-11-2007, 01:22 PM

thats tight... it will look so clean when finished
