When I added my vss, I had a similar issue with my civic's speedo being unable to manipulate the pulser.  This forced me to swap over both the speedo AND the odo (regular and trip).  One caveat you forgot to note, at least in my case, is the stop for the speedo needle.  The integra had a stop on the speedo face to keep the needle from going past zero, while the civic had an internal stop.  By placing the integra speedo on the civic face, you no longer have a stop to keep the needle at zero.  It's not a huge deal, but it makes getting the needle initialized at '0' before install important.

actually, i did note that in my post

look 7 posts up from the bottom on the first page.

Whoops, my fault. I was replying to r4adkshn's post.

Good tech though. I just wish I had found this site about 6-7 months ago.

so which vss will provide the correct incrementation on our crx guage faces?

[rextec]

anyone?^^^^^

Are there any speedo guts that will move the needle correctly for the '85 Si 140mph speedo?

I've kinda grown attached to mine, but I may need a vss for a "project" in 6 months or so

i am not sure, but i think the 88-89 teg speedo will be similar. there is that stop problem though...

130 on the teg speedo face is about the same angle as 110 on the CRXs, so the 140mph Si speedo may be close. i'd grab a gauge face from a junkyard 88-89 teg and compare to the 140mph Si speedo. if, when lining up the zero-marks, the 130mph marks line up (the 88-89 gauge face actually ends at 135), then you should be able to use the 88-89 speedo guts with the 140mph Si face, and trip odometer.

Whats the differance between the JDM instrument cluster and the USDM one?

I found a JDM one on ebay, but it looks like the US one to me. But, I don't know much about my crx; I got it less than a week ago.

1: the hvac controls are on the left (on the right for USDM) -- because jdm cars are right hand drive.

2: the dash brightness/rear defrost switches are on the right (left for usdm)

3: the tachmeter redlines at 7000rpm (ZC)

4: the speedometer is in kph, not mph

I just got an '89 teg speedo and pulser from a junkya....uh, auto dismantling establishment. One thing I noticed is that the teg pulser with the two inductive pickups on either side of the rotating disk (don't know the name but it's the disk that rotates and causes the pickups to generate "pulses.") also has a spacer under each screw attaching it to the speedo frame. If the pulse generating disk on the CRX has a smaller diameter it will not generate the pulses in the pickups unless it was inserted deeper between the two pickups. It seems that a person could remove or grind/file down the spacers to get the pickups closer to the center of the disk and it would work. I'm assuming, of course, that the devices on either side of the rotating disk are inductive proximity switches. I will check this out later.

Just a thought.

Doobie.

i have already mentioned this, and noted it in one of my earlier posts. that is why i simply used the HF pulser.

Shadowboy,

After reading your last post I looked back and realized what you were saying. Thanks.

What I still don't understand is how to test to see if the pulser works. Do you apply +5volts or +12volts to the common connection and read the other two legs as you spin the speedo?

The reason I'm curious is because I'm getting ready to swap an '88 teg head on to my '86 Si block. I would like to have an acurate speed reading.

Thanks in advance for everyone's help.

i didn't actually test to see if the teg pulser works in the CRX cluster. i was merely assuming it would.


i did not test as my crx is an HF and i already had a working pulser. I just wired the integra "amp" with the CRX cluster so that it would plug right into the teg harness (which i used to wire the CRX for EFI).

Doobie,

I am using an 88 teg speedo. The way to check the vss pulser is simple. It may take a third hand, though. Attach your ohmmeter across the two terminals of the vss. It should initially, read as a short. Spin the speedo with a small screw driver or the like, and the needle should bounce to an open. Oh, you'll need an analog meter. I found the pulser didn't work in my civic unit, but that may not be the case for you. What's it hurt to try, right?

[Dobajara]

Thanks again for everyone's help.

I'll try the test. I have also thought about contactring Denso or Nippon to see if they have any suggestions.
