i guess this thread is dead........ kinda sucks

Is it? Ive been very busy with the birth of my daughter. I have slowly been getting parts together still and picking away at it. Been slowed down by building my DB1 as well at the sametime. Just finished my building my shop at home so I'm back full time on it. Well, I guess full time on my spare time...haha. I'll dig around for some recent pictures. Currently on schedual to finish my custom intake box. Next will be the dump tube. Sorry guys I have been so lazy about keeping this updated. Not that I usually did from the start but I could do better. Stick around!

DB1 project. Full suspension rebuild from this summer. Sorry, big pics are coming. Don't have time to resize guys.

Hey the motor looks great, I have a question a little off topic, I have a 1992 gsr, and I'm getting a check engine light for vss, since it's cable driven I can't figure out where the ecu gets it's electrical signal from? Any help would be helpful. Thanks

Bond

The ecu gets the vss signal from the instrument cluster. There are two terminals at the back of the cluster where the vss is located. These "terminals" look like to brass colored screws located on the back side of the cluster. Directly behind the speedometer. Output of the vss is 4 pulses per full cable revolution.

To test it. Remove the cluster. Use a typical pencil that you would use for school work. The hex shape of the pencil is the exact size of the speedo cable. Weird right? Maybe Honda engineers really thought of it all lol. Anyways, connect an ohmmeter to the two screws. One lead to each screw. Set it to check continuity. Now rotate the speedo using the pencil and watch the meter. Like I said before, for each revolution there is four pulses. So during a full turn of the pencil (speedo input) there should be continuity 4 times.

Oh, and turn the pencil counter clockwise when looking at the back of the cluster!

Thats basically it for the VSS. If it doesn't pulse or is missing one then thats your problem. If they are all there then check your wiring to the pcm. If thats all good, your PCM is faulty!

Thats the best I can do over the internet. Hope thats any help. If needed shoot me a private message and I can post some diagrams for you.

Been messing with the idea of converting to coil on plug. AEM makes a nice kit. Anyone here running one? Thoughts on the kit? I figure it's not an upgrade in performance from my current setup, but I would think the COP system is more reliable. Not sure. Input is welcome.

Going to be focusing my next efforts to finishing the 60mm tial dump piping. Hopefully have pics up of that soon.

That's super handy to know! thanks!
Do you know if you can feed an electronic VSS into the dash? ie; is the needle electronically driven, or some fancy voodoo gearing and actually driven by the cable?

Bond

The needle is mechanically driven by the speedo cable. The fancy voodoo is actually in the speedometer itself. It uses a weighted type of slip coupling to control how much the coupling slips and reads the speed according. Pretty cool to check out if you ever have it apart. You can run a electronic speed sensor in the trans and convert to electrical but this requires a electric speedo either aftermarket or oem unit from a later year.

This build thread will be my first ever post! Long time VW guy coming to the other side. This build, your fabrication skills and your attention to detail are AMAZING! Keep up the good work and congrats are due on your recent marriage and the birth of your child. Thanks man, you are an inspiration.
