PS for the lazy's its called the "Universal Speedometer Signal Interface" and its 79.00 from that website.

Oh also, sounds like you cant but, couldn't you just use Hondata to convert the signal? I thought Ive read of other people doing this?
Yes, you can use Kpro, but you will need to buy an extra harness or a conversion harness to run the correct signal. You may also need to send in your Kpro in to be "re-pined". So basically it is more than $79.00.
 
i know this is an old thread, but i want to bring it to life and shed some light on the topic. well, i was thinking of getting the 06 si tranny and use with my z1 motor in my ep chassis. right now im using an a2 tranny. would this converter unit work for getting the z3 tranny to work with my set up? is it a simple install z3 tranny and connect the converter unit?
help is greatly appreciated. thanks in advance.
 
Installation is pretty easy. If you have ever run wires for speakers, foglights, etc, then you will be fine. Basically you just cut the VSS wire before it splits to go to the ECU and the cluster. Then run the wire coming from the VSS into the input on the box. Get a wire and put it on output 4 (could be output 3) and run that to the VSS side that continues on to the cluster and the ecu. You have to hook up another wire to the "Power" slot, and the "Ground" slot. Then you have to set the dip switches. It comes with instructions and you should basically follow them. However, the dip switch settings were wrong. So I had to figure it out between what it had and what I thought would work. Switch 1, 2, & 3 should be "up" and switch 4 should be down. That should get it to work the ecu and cluster just like stock. Depending on your tire set up, you will probably need to fine tune it after that. Mine was off about 5% or so. I had my buddy pull up next to me in his car and we matched speed. I highly recommend having someone else in the car. I didn't, (not a smart idea). I also testesd it after that on radar traps and it was perfect.

Hope that helps:up:
This is not the same as bigcalidave's converter correct?
 
i know this is an old thread so i hope someone still checks it....ok i have a k20z1 and the 06 tranny that goes along with it but im putting it in a ef9 so i knew i would have to run the 04 tranny so i just got my harness converted so does that mean i cant run the signal converter cause i changed my wiring harness??? im also running 04 k-pro.....please help very confused...thanks

did you get a2 harness or you still got z1 harness? from my understanding, the a2 harness is what you will need to run that set up in an ef. The signal converter unit will help you use the tranny with that harness and ecu. correct me if im wrong guys. hope this helps.
also, i want to run a z3 tranny with my set up, im sure it will work with this converter. but i want to clarify. who here is running with this converter unit?

As far as the wiring goes for your motor, I am definitely not sure of what you should do except a lot of research. I am going to guess, and say that if you are using a z1 motor that you will probably want to use an a2 harness for it or a z1 one harness that has been converted (I believe Hondata sells it or Rywire?) to run on an a2 ecu. The z3 tranny should work just fine, but you need to read the instructions posted before about what you have to do. Basically you will probably have to get the plug for the vss from the donor car that you got the tranny from. Then hard wire it into the a2 wiring harness. I would NOT recommend cutting the vss plug from your good a2 harness. Again, DO NOT cut your good a2 vss plug from your good a2 harness (I have destroyed my 05 tranny and am currently using am 04 tranny with my original a2 vss plug). Just splice into the wiring of your original vss plug and have two plugs. One for 02-04 RSX-s trannies and one for the 05-07 trannies, I am not sure if the 05-07 plugs fit the 06-08 Si's.

The converter is adjustable so it works for different scenarios. Put it this way, I found it by looking on a mustang site. Actually the setting that works for us is not a "standard setting" in the book. It took me some guess work, I mean thorough research:D, to get it working. As far as hooking it up, if you can install a car radio or run your own wire to an amp and speakers then you can install this.

This is not the same as bigcalidave's converter correct?
I think they do the same thing but they are two different products.

If you did not convert your harness, the answer would be yes. I do not really know exactly what they do when the "convert the harness" so I do not know if the signal converter will work for you now.

I think you might not need the signal converter, you just should enable 05 vss mode in K-pro since your harness is converted, but I am not sure.
 
You have to do more than just switch the case. There is and extra set of teeth on one of the gears that are in 02-04 trannies. If you simply swap casings, your 05-07 tranny never came with this extra set of teeth to turn the speed sensor. So once you drill the whole for the speed sensor it will just sit there reading 0mph forever.

If you want to run an 05-07 tranny you don't have to swap casings just get a signal converter. I have been running one since December of 2005 and have never had a problem, except for a loose ground (my fault). This way you can use either tranny with little effort.

Okay, you're crazy as hell and I cannot believe that you actually said that the 02-04 trannys have an extra set of gears that turn the VSS speed gear. The FACTS are the VSS is turned by the differential, its basically pressed on there and as long as your tires are moving its gonna turn the VSS and you'll have speed.

THIS IS HOW YOU GET A 05-06 TRANSMISSION INTO YOUR 02-04:

-Get a 05-06 Tranny
-Get a 02-04 VSS - Speed Sensor
-Buy a 02-04 Differential or this is a great time to get that LSD quaife or whatever you want but it has to adapt with the VSS gear.
-Exchange the 05-06 Final Drive Ring Gear and put it on the 02-04 differential or the LSD differential but make sure theres a VSS gear on it.
-Go to a machine shop or drill a hole big enough so the VSS can slide into place and turn(s) as the differential turns.

What so difficult about that?

Thats it, use a 05-06 Tranny and modify it with 02-04
 
I did this with no machine shop and a uni-bit. I have an 05 tranny and i just got the 02-04 diff and VSS then i drilled away, i checked to make sure the vss was in the hole straight and then DONE! this is not very hard and there is NO need for all of these harnesses and complicated wiring conversions when you can just do it the old fashioned way!

Hey can you take a picture of your tranny so we can see? I already believe you but some people on the internet is really freaking retarded and cannot comprehend that its been done because they are incapable and stupid.

Check out this joke name neo_ speaking about how hes never seen it done. What a moron cause he said someone with 13 posts must not be believable.

My way is not the only way it just happens to be the first complete way posted in this thread. I never said mine was the only way and you calling me crazy, kind of makes it sound like your way is the only way and mine is crap. If you look at this thread, someone needed help and the first post was not very detailed. Perhaps if you would have been available in June of 2007 this thread may have went in a different direction but you did not, so the rest is history. I had my setup for almost two years with no problems and when a problem did occur it was mechanical because the shop that changed my clutch (again) botched it. As a result, I lost my 05 tranny. Some people, like myself are not comfortable cracking open the tranny cases to do what you suggest. If you are comfortable with it, more power to you. I actually had a shop try it for me in 2005 when I was finishing up my swap before the motor was even in the car, because I figured it would be easy since it was out the car already. Well only 1 of the 3 shops I took my tranny to would even touch it and when they did finally open it up is when we learned that the speedometer drive gear (or speed sensor ring) on the final drive in an 02-04 tranny does not exist in an 05-06 tranny. I was not going to have them experiment on my practically brand new tranny, Again this was 2005 with an 05 tranny, hell it took me about 4 months just to find a crashed 05 Type-S with a salvageable transmission (less than 6,000 miles on it and no damage from the wreck). So again since this was 05, I searched many different honda/acura sites for info on the 05 tranny. There was not a lot of information on the 05 tranny. Hell I drove for about 4 months with no speedometer what so ever [PRC ecu, no K-PRO :( back then and no reverse either, that use to suck]. Eventually I put together enough information together to come up with a solution that was perfect for me, most of it was from a s2000 site. So please do not call me crazy for not waiting 3 years for you to post up this information for a solution to my problem or the guy that started this thread almost 9 months ago. I am glad that you have posted another way to solve the speedometer issue because it gives everyone choices which is great, just do not call me crazy for offering my two cents to others for the same thing. Oh yeah and I did screw up by saying (thank you for catching my "extra set of teeth mistake", sorry about that)

What I should have said is that the speedometer drive gear (Acura part # 41312-PPP-000 illustration 003) on an 02-04 RSX-S tranny does not exist in an 05-06 tranny. Therefore if you are not comfortable with doing the following:

1. Remove transmission from vehicle
2. Either drill and tap the rear speed sensor location to accept the 02-04 speed sensor, or swap transmissions cases.
3. Add the speed sensor drive ring to the final drive.
(Last section at the bottom of the page called "How can I get an 05-06 transmission to work in an 02-04?")

Then try the converter box because it worked pretty easy and was cost effective for me imo. It also gives me the ability to just swap out an 02-04 tranny for an 05-06 tranny without doing anything else once you have it setup correctly, just PNP. But you do not have to take my word for it. There are many different things you can do to get the speedometer to read correctly besides this, so please post and share with everyone.

Do keep in mind that if you are planning to put in a LSD such as a quaife then you will have the tranny open anyway so adding the speedometer drive gear and drilling out the case to accept the 02-04 speed sensor may not be a problem.

Hey after your story of your crazy 3 yrs experience, I'm going to apologize for calling you crazy. You're right, being frustrated and need something to work and theres nothing on the forums or no knowledge anywhere is extremely frustrating. I apologize.

I was already refining the 05-06 tranny converted to a 02-04 VSS like over a year ago but I was never into the k20a.org forum, I was more of a honda-tech guy. So my bad.. I'll be here from now on and there occasionally but who cares, I'm no guru. Anyways when you said plug and play I also have a bit more to add on the 05-06 trannys.

When you fully convert a 05-06 tranny with a working 02-04 VSS speed gear and VSS sensor you can just leave the original 05-06 VSS in place since it would block oil from escaping anways. But thats the beauty of it because now you can also use that 05-06 sensor if you ever plan to swap it in a 05-06 car that uses that sensor but instead of plugging into the 02-04 VSS sensor you plug it into the 05-06 sensor and use that. This makes the tranny not only VALUABLE but COMPATIBLE, I mean, look at the resell value on this transmission that you just modded. You can sell as a 02-04 and 05-06 VSS compatable transmission with all the goodies of the 05-06 transmission (4.7 Final Drive, Good gear ratios). And if you add a LSD bam, this transmission would be and will be hot as hell.

Tell me what you guys think about that?

bspcivic, im sorry I don't mean anything by my words dude I'm such a friendly guy I have no idea what happened that day of that post, probably bad day with the girlfriend you know?
 
No prob man. xhadudkenx I think your right, that would be a good idea. I would like to get an 06+ si tranny like that for the LSD. Having it already compatible with both types of vss takes all the headache that we both went through out the window. All the new guys doing swaps have it easy :)
 
Thanks for the great info guys. I currently have an k20z3 in my 93 Integra. I got the 06 conversion part of it done to run the 02-04 VSS. I hear that the 02-04 shifter box and cables will not work with the 06 tranny because the shifter arm is different or something to that extent. What can I do to fix this problem?

When I had my 05 tranny I used my 02-04 shifter box and cables without any problems. I do not think they changed an 06 tranny from an 05 so you should be fine with the shifter box and cables.
