What is the conversion value for t56 VSS and 4l60e?
What is the conversion value for t56 VSS and 4l60e?
Hi guys,
I have a t56/lt1 in a 1984 jag -- when I had a 4l60e installed previously, i got my speedometer readings from the VSS sensor, which fed into a conversion box that converted the pulses to something the Jaguar could read. Now that I have the t56 installed (with an M6 tune) my speedo isn't reading anything at all.
I was wondering if anyone knows the conversion rate of the 4l60e vs the t56 -- the guy who makes the speedometer conversion boxes made it adjustable -- i just need a ratio to plug in.
Any help would be great!
Thanks,
Tyler W.

4L60E's use a 40 ppr VSS signal, early T56's use 11 ppr and later T56s use 17 ppr signals
How that relates to your converter box Im not sure, just try different numbers starting with approx double or half

Alright --
I noticed in TunerCats you can change the pulse values -- has anyone tried this? Could i just change the pulse values from 17 to 44? Or is the VSS in the t56 completely different?
