Lingenfelter box is for adapting a Gen4 58 tooth crank down to a Gen3 computer which can only read a 24 tooth crank.

Times were a bust. This car eats ******* fuel pumps like a fat girl eats cake. Stay tuned.

Nice. I used to have a 94 6spd car that I got new. Damn, I am old...

How did you get the LS computer to work with the lt1 4l60?

It's an LS 4L60E he's using..

It is not necessary unless you are using a gen 4 crank/cam, they have a reluctor wheel on the crank that a sensor reads off of that has more teeth than a gen 3. (iirc it's 58 teeth compared to 24 teeth on the gen 3.)
The cam sensor also reads differently if you're using a single bolt cam and a different type of sprocket.

The box basically is a go between, it reads the higher signals from the gen 4 stuff, dummies it down to a gen 3 equivalent, and then sends the signal to the PCM. Now, if you're running a gen 4 engine and PCM, you wouldn't need it.
It essentially allows anyone with a gen 3 PCM to use gen 4 hardware without changing the harness and computer.

Ok thanks, so its basically between the gen's of the LS and has nothing to do with the actual LT to LS swap then... perfect. I read that the higher tooth count equals higher resolution, so I guess its best to use all the 58 tooth components then if possible.

It shouldn't matter if you're gonna dummy it down anyways. I would say the only reason to use it is if you are purposely using newer stuff with the older.
If you don't have anything yet, just go straight gen 3 and cut out the extra cost. The box costs a hefty $250.
But so far as swapping LT to matching LS, it is unnecessary.

I prefer the 24X, that's just me tho.
