The wheel slip number is showing the average rear wheel slip vs. the average front wheel slip, so a small percentage when driving should be expected.
For the more in-depth wheel slip description, this value isn't to be confused with different rotational speeds from different rolling radius in the front vs. the rear. In order for a tire to produce traction forces, there has to be some amount of slip. In the case of driving straight, this means that the rear driven wheels are actually spinning slightly faster than you'd expect based on rolling radius and vehicle speed. The reverse is true for any non-driven wheel or when braking; those wheels will actually be spinning slightly slower than expected. The faster you go, the larger this slip ratio becomes because more tire traction force is required to overcome aero drag. At 0 speed it should be at 0 (but per the post above, sometimes this number calculation doesn't do a good job at low speeds). At 45 mph, I was seeing 1% wheel slip. I'd imagine at highway speeds, it's possible to see 2 or even 3% wheel slip. |
Checked it out last night, like posted the yellow top read out is the lock up percentage of the eLSD. Just cruising it is very low as you don't need posi lock up. Accelerate from a dead stop and that percentage will jump up as the eLSD fights for traction. Mild pull and I got it to jump up to 52% pretty easily.
Lower display is a bar graph of what would be considered rear tire slip. Cruise is nothing, slowing down is nothing, but acceleration gives you a reading. Hard acceleration from a low speed will light up the graph pretty good. Mild acceleration while cruising will light up a bar or two.
