Cable X question? I am having a problem getting my cable x box to work. I performed the field test and the motor spun the speedo up to 60mph just like it was supposed to, however I cannot get the motor to do anything once the signal wire is hooked up. I checked the signal wire and I am getting signal, but the motor still does not move. I am using the vss output from the computer although I have tried to run a wire directly from the VSS itself using the purple wire. If anybody has any suggestions, I would greatly appreciate it.
Also, I spoke with the techline at abbott and they informed me that the 4l60 trans should use a 40 tooth gear setting. Is that what you guys are using?
Thanks
Chad

I had a look at the Cable X last night whilst browsing the net looking for a VSS for my TH350 setup.
I have emailed cable X but havent got a reply yet.
It looks to me as its a 3 wire sensor like it is a hall effect setup, the LS1 uses a 2 wire sine wave sensor, both wires go to the PCM.
I have been told this 3 wire setup hall effect is no good on LS1 PCM's.

the LS1 VSS (and all GM VSS) have only one signal wire... the other wire goes to ground.
its just that most of them are grounded in the harness or in the ECM (or PCM)....
to run a GM VSS on a aftermarket device, find the wire thats not the ground, and run that one to it....

I have a cable-x on my t56, running directly off the VSS. It works fine....well up to about 100mph, then it stops working, with the speedo going to 0, until Im below 100 again..
Also seems slow to start working from a standstill, sometimes i'm up to about 20mph before it starts working, although once on the move, it reads ok.

So Stevie let me get this straight I can use a 3 wire hall effect sensor for VSS?
Its just everyone has told me I need a magnetic reluctor setup like factory cars have.
I just need a signal for the PCM so it doesnt stall.

Not saying that. My T56 came with a 2 wire sensor, which I'm assuming is magnetic.
However, taken from the instructions...
One of the dip switch settings on the unit is regarding hall effect.
Quote "Switch #12 in the "on" position for "hall effect"
From that, I would imagine it will work from a hall effect sensor too. But as the hall is a 3 wire, which requires a power feed of either 12v or 5v and of course a ground to operate, you would need to make sure the sensor still has that, with the 3rd, signal wire going to the Cable X to operate the speedo, and also to your PCM, to keep it happy.
The mag 2 wire simply needs a ground, with the other being the signal.
get any of the wires mixed up, and it wont operate.

Thanks Stevie,
I'll give it a shot again directly off the VSS. I used the purple vss signal wire on my 4l60e but it didn't seem to operate the cable x. The other wire is yellow which I believe is the VSS low signal wire. I'll give that one a shot. You are running yours as a none hall affect... correct?

mmm not actually sure what I have no 12 set at....
I had the car jacked up, and was messing with the dip switches to calibrate the speedo. It was working, so i closed it up, and its well stuffed in behind the dash now.
I got the switches wrong several times initially, so once it was all working, i just left it well alone.

Ok so this unit works with the existing VSS magnetic setup.
Gotcha now, my problem is I have a TH350 and need to run a VSS & a Mechanical speedo cable, seems its 1 or the other, car is 1977 so no ABS to tap into.

I dont whats on your trans, but if there is any speedo output at all, then shouldnt it work ?
It does apppear from the instructions, that it can either read hall, or magnetic. I am currently using it with a magnetic sensor, but there is a switch in the box, to enable it to read hall, as I said.
What more do you need ?
I am not using the stock computer that the LS1 uses. The T56 VSS is only being used to drive the cable-x, which in turn drives my mechanical my speedo.
There is no reason why the vss couldnt tell 10 cable-x's, or pcm,s or whatever if it had to.

ahhhh....
so your trans is actually a cable output, and you need an electronic signal from it.
The opposite of what a cable-x is actually for. ??
I know that some motorsport places here ( UK ) do an inline thingy for speedo cables, so you can get a pulsed ouptut from them. Usually used for trip computers in rally cars etc.
Failing that, you could make up a toothed wheel, and attach it to your propshaft/driveshaft, and hook up a suitable sensor to that.
Some aftermarket speedos would work in a similar way.
While this probably wont fit your gearbox, I assume its the sort of thing you need ? It will give a pulsed output, via your cable. No idea on calibration etc.

Yep and Yep.
Those adaptors are normally a 3 wire hall effect setup, supposedly no good for LS1's.
I have looked into the propellor shaft setup and this will more then likely be what I'll be doing.
