Chinese SS182 digital speedo installation tips
#111
ambeos5, I guess maybe the last thing would be to open the case up and determine if you have the SS182 (i.e. the Koso ripoff), or the fake SS182 (the ripoff of the ripoff). Might not get it working, but might add more useful info to the thread.
Kyle, I suggest finding someone local to you who has the electronics knowledge to help you put the extra parts in. If it is actually a genuine SS182 try the cap and resistor filter, with the hot end of the resistor between the cap and tach. And also try the hot end of the resistor between the cap and ECU tach output, since it seems to work differently on different models.
Guys, believe me, I do feel your frustration. I've been designing electronic gear for 20 years and it took a lot of trial and error to get my tach to work.

Kyle here are the links to the equipment Doc is talking about
Resistor Here
Cap Here
wire the cap as a bridge from tach input wire to the output wire from the bike, wire the resistor from the tach input side of the same wire then the other end of the resistor to a ground on the bike, hope this helps.

I think the only info in this thread about the fake SS182 is that Sabotage could never get it to work at all. He ended up getting a real SS182 (aka fake Koso), which he did get working with a little different setup than I used (no capacitor, just a resistor from the SS182 tach input to ground).

There are a few different possibilities.
One is that the tach is looking for a signal with a different voltage range. The added resistor can help with that on a real SS182 by making the signal pulse from the ECU smaller. That seemed to help both me and Sabotage.
another is that the tach signal may be too noisy for the tach to respond to properly. The cap and the resistor together can create a filter that takes some of the spiky noise off the signal. That seemed to help in my situation with an F1.
thirdly, since we don't have any evidence in this thread of the fake fake working at all, it might just not work, period. Since it looks completely different inside it may need a completely different setup to run. The typical solution for the really cheap Chinese tachs is to wrap some wire around the #1 spark plug wire and feed that signal into the tach. Maybe it would work that way?

this fake gauge is the biggest waste of 50 bucks and a piece of trash, i honestly don't see how the real koso would work any better (as in easier to install) how can you sell a fake of a fake for 10 bucks less, didn't know the difference until it came to me and it was advertised as a ss182
