NOTE! Diodes in pic are NOT the proper diodes. the part numbers are listed in the first picture.

PN= 1N4004 - 2 of them
also you need a  15 to 18 volt Zener Diode
Pn= 1N4746A

Hi,

I was wondering how you wired up the stock tach with your EDIS 4 setup?


http://www.megamanual.com/ms2/EDIS.htm

i had to do this. no other way worked. it lists the part numbers you need. simply solder
them together and make sure the bottom 2 do not touch each other. shrink wrap them
or use liquid electrical tape then slide heat shrink ofer them. then shrink them down while
liquid electrical tape is wet. once it dries the heat shrink will not slip around.

another pic:Posted Image
from the above pic i hooked one of the double end side (D-1) to wire 12 (below pic)
and the other (D-2) to wire 10 (below pic) on the EDIS connector. either one can go to either negative coil wire.

Posted Image

the single side (D-3) from top pic goes to cars harness white connector wire shown below.

to save you the hassel of making one. i know that the 1990 only Eclipse turbo cars had one on them.

you will also have to go to a real good electronic store to get your diodes. radioshack had nothing.

if you can not find them i can get them for you and make them up as well.

i know the connector is white and goes to a brass colored resistor then comes out black, then goes to NEG on coil. there is no longer a coil. that is where i hooked it up.

Would it be possible for you to post a pic of the completed diode setup? I'm confused as to how to solder the diodes together. I found a few good sources for diodes on ebay.

ok in pic 1 above, you see the short line right above the triangle near D1. it goes horizontal. also there is a short line right abovethe triangle near D2 also horizontal. that represents the gray stripe on the diods you see in pic 2

D3 zener diode has the line horzontal below the triangle. the gray stripe pointis towards the other 2 diodes in the pic.

basically twist them together solder



so

turn D3 up side down and solder the end circled to the other 2 diodes circled in RED.  all gray stripes should face each other.
in the picture below this is not a Zener Diode. the pic is only to show proper orientation when soldering them together

make sure to heat shrink any exposed leads. that way nothing will arc to ground.

the first gen 1990 eclipse "ONLY" had one of these on it. if you can find one.
it is just easier and a ton cheaper to build it yhourself.

I just installed the diodes by following the instructions above and the stock tach is working perfectly. This should be made a sticky in the mpi section maybe. Thanks importwarrior for the help.

So....Does the Positive side...going to the white wire on the harness.....Does it "tap" into the existing line...? I don't understand this or What the (D-3) is? You got anything for me Importwarrior?

same question... I think?
do yo retain the stock brass color thing and connect to where the coil negative
terminal used to be.... or connect the free end of diode D3 straight to the stock
white wire/white connector shown above ?

yeah, this sorts stuff should be in the FAQ

side note:
**ALSO** a megasquirt fuel-only
AND a megasquirt mpi with distributor & timing
AND a megasqurt EDIS. CaliConquestAlex comment saying "how EZ it is", stuck in my
mind smile.gif

I really gotta study his and buttons' threads.
Button documented switching between TBI to MPI... made it seem real ez
I gotta read over those threads .....before they dissappear

I re-read this again....So....There is nothing hooked up the the black side of the gold box anymore? The gold box is gone right? I'm pretty sure I understand now. D-3 is the completed neg side for the tach signal....and it goes to the white wire. I gotcha...i think.

test it with the gold filter still attached, you may or may not need it.

do you know where it is physically located on the 90 DSM ?

I'd think the non turbo 2.0 may have them also as its the same electronics ? ...so
more 1990s to choose from

I'll build the circuit as u kindly posted, but I may actually be able to find a 90 2L DSM quicker than I can get those diodes smile.gif

I am having trouble identifying the correct wire in my situation. I have a red arrow pointing to the item i think it is.
Posted Image

I soldered up the diodes how i thought they should be and used the red arrow wire. No tach signal.

I am a little confused to what the little symbols mean on each diode, does the way the arrow points mean something. I see white/black lines on one side of the diodes i bought, is that the 'output' side? I am not sure if there is an 'input' and 'output' side to these things.

Diodes are like check valves.  They only let electrons flow in one direction and that is what the band is indicating (and why an LED or light emitting diodes only "lights" when wired correctly).  The two lower diodes in the diagram are regular diodes.  The top Diode is a Zenner which blocks current flow until it hits a certain level and then allows it to flow in the reverse direction.  Think of the bottom two as a traditional door, it only opens one way.  The top diode (being a zenner) is like a door that swings both in and out, however it only swings out when the room reaches its maximum capacity and required it to do so.
