On my conversion I am running a Keisler TKO 5 speed transmission. It does not have a VSS output. I want a VSS so I can tune easier. Do they make an VSS adapter that will go into the speedo output on the transmission and let the speedo cable connect to it and give me a place to connect for VSS? I am keeping my mechanical speedo and only using the VSS output for tuning.

I hope I have made this clear enough to understand. Any help would be greatly appreciated.

I believe that autometer makes one to power their electronic speedometers. It has the cable connection for the old style cruise control units.

I found this and it looks like what I think the part should look like. I can connect the adapter to the trans, then the cable to the adapter and get my pulse from the pigtail. Anyone have any experience with this?

My Keisler TKO has both mechanical and VSS outputs. When did you buy yours?

It has been installed since 10/2003. I had the trans in my garage for about 6 months before I got around to installing it. On the back of the trans, on the drivers side, there is a black plug that has two wires coming out of it but that is only a neutral switch. If I am not mistaken the VSS is on the passengers side of the trans.

That's a two wire sender so it will put out the correct type of signal. What program are you using to tune the pcm and what pulse output is the vss?

It says it is an 8 pulse generator. Does not say whether it is a sine wave or square wave output though. I am using HP Tuners to do the tuning.

I am using the Dakota Digital "SEN-01-4160" on my t-56 that was converted to a cable speedo drive. I have it installed inline and the cable passes through to drive the speedo. I am also using HP Tuners and it works great.

Nice find. This Dakota Digital is even closer to what I need for my Keisler trans,

What are the prices on those units?
Do they allow for using an electric speedometer?
I'm putting an LS in my 68 vette and was going to run a mechanical tach but no VSS for the computer.
I've heard of stalling problems without VSS, so now I'm thinking I could use the adapter and run all electronic guages.

Gary, they put no prices on their webpage but I would suspect that Summit or Jegs or someone like that might sell those adapters. If you follow this link you should be able to look at the adapters and see one that you might be able to use. I still am not convinced about the adapter working with the tunnel clearance. I might just have to buy one and put it to work and see. Seems like they were around $40-$50 which I am okay with if it gets me what I want and need for the swap.

Here is a link to DD's webpage with pricing. Easy on the pocket if it works.

From Dakota Digital, you need p/n SEN-01-4160 .

One other note. I was a post where a Tremec had an adapter on it with a pulse output as outside the range of the LS computer. Dont know if it's relevent, but worth checking.

Does the Dakota Digital SEN-01-4160 put out the proper signal for the LS1 VSS input to the PCM?

I have never heard of that. With HP Tuners, you can go all the way to 0 pulse in the settings. The last time I checked, EFI Live only went down to 10 pulse. Maybe that is what they were talking about.

Just wanted to bump this up again. My tremec has a speedo cable that is the ford style (I assume) at the trans end and then connects at the GM Speedometer.

I do have HP Tuners but I paid someone, Chuck CoW, to tune my car last weekend. He did an excellent job with it. There were some tables that cannot be tuned if there is no VSS.

So with the decsription above of the speedo cable, does the SEN-01-1 by Dakota Digital seem like the correct one?

I'm not sure if it will connect to a ford cable or not.
