Installing aftermarket Cluster

[rbm]

Sorry cdrp, Hugoo asked for tach information.  Tachometer reads engine speed, not road speed.  Did he really mean speedometer sensor information?  Sorry I took the question to mean engine speed.

Sorry, you are right, I miss read the comment, I had no problem with the tach, you can use the signal from the moronic directly, just program the pulses per revolution on the tach to 1, this will do...

[hugoo]

Thx both of u! :yes

So now i am sure i read the rpms right 😀.(engine speed)
But now i am confused again about speed! I read on thus forum that for road speed, you had 6 pulse each rotation, but now you are saying 5? Just to be qure and correct as possible, should i use 5 or 6 pulses for roadspeed?
Thx

[cdrp]

The best way is to compare the speed with a GPS, and modify the settings accordingly, more pulses o tire diameter....

It's 6 pulses per wheel revolution.  As cdrp says, program the Koso to use 6 as the multiplier and estimate the wheel circumference.  Then use a mobile phone based GPS program to fine tune the circumference number so that the Koso speed and GPS match.

Thx! I ll compare the speed to my gps as soon as my tires are chanced!
Thx again for all the help I was nt expecting the koso to be working allready and i am really happy it is!

Sorry to resurrect an old thread...

I built the low pass filter in reply 2. It helps quite a bit, but I still have some jumpiness in my tacho, which is an Acewell.  I want to try the one in reply 4. My question is what capacitor do I use?  I'm not understanding the notation in the diagram. Thanks!

Although it was been a while, I believe it to be 33 nano farad.  The free program that I used to draw that was Texas Instruments TINA, and it is loaded on the other computer, will confirm for you later today.

Cheers

Thanks Rick.  Please do confirm when you have a chance. 

Also, do you know it is possible/advisable/inadvisable to use a capacitor of slightly higher or lower value? If I recall what I saw at the store yesterday, I don't think that my local Radio Shack had a a 33 nano farad in stock, but I think they may have had something close (I think they had 22 and 47, but I could be misremembering).  If exactly 33 is crucial, then I can order one on-line and just be patient for a few days while delivery is pending.  TIA!

[KJustin]

Just thought I'd report my progress. Built and installed the circuit from reply 4 but with a 47 nano farad capacitor instead of a 33. Just fired and revved the bike in the garage (didn't have time for a full test ride) and the tach looked very steady and accurate. I'm going to call it a success. Will report back if there are problems upon a full test ride. But if I don't post, future readers can assume that this solution worked for me. Thanks all for the assistance. Best, Justin.

Good followup, Justin!

sorry about reviving this old thread. Where exactly did you take your signal for the tach ?
Was it pin 19 from the ecu? Did you use the wire connected to pin 19 in the main harness ?

[KJustin]

I think I used pin 16 on the speedo plug-in, which is the black/blue wire. I'm not sure what pin that is on the ECU. But I bet someone else on here will know.


Unfortunately I'm currently separated from my bike and documentation, so I can't confirm. But I'm about 95% sure.

I've been suffering from the jumpy tachometer for a few years now and found this thread, unfortunatly the schematics on reply 4 is gone, do you think you can explain the circuit?

This is the schematic to which you refer; it is visible in reply #4 so check your computer or phone settings.

Thanks, must have been looking at the post while not signed in!

How about introducing yourself in the Welcome to Motobrick section and posting a few photos of your bike in different profiles, Mr.Tom?

Sounds like a good idea, I'll get on it this weekend  :2thumbup:
