LS1 / T56 Update #39, Abbott Cable X Converter

[Phantom]

For those of you doing LS1 and planning on using hte Abbott Cable X product to translate the electronic speed output onto a mechanical dirve for your stock speedometer be advised:

I talked with Cable X today and found out that, even though they don't put it in their literature, that they strongly recommend soldering all connection and then using heat shrink tubing around it. Evidently an even slightly weak connection will cause signal loss and erratic behavior of the speedometer. I can attest to this. Oops

The cable x box is a sophisticated way to drive a speedometer when using the LS1 (which does not have provisions to drive a speedometer cable).

 

Another option is to use parts from JTR/Stealth which allow the LS1 4L60-E (or LT1 4L60-E) transmission to run a speedometer cable the old fashioned way -- with speedometer gears. The parts are shown in the book, Chevrolet TPI & TBI Engine Swapping, but they should be posted on the JTR website in the next few months. The cost of the JTR parts is about the same as the cost of the cable x box, but the parts are much simpler, and less likely to break.

Now if you just had something that worked with a T56.

Hey, I know you want to keep the stock gauges, but I still think an electronic speedo is a great solution.

JTR/Stealth does sell parts to make a T56 drive a speedometer cable, but it requires the customer to do the machining, or pay someone to do the machining.

The parts are shown on this link:
