I have a 2012 Camaro with a Circle D Triple Disk converter and my lock up times were slow(2.4-2.5 seconds). I noticed that messing with the Ramp numbers didn't shorten the time, however increasing the Ramp 4wd Lo tables does. Now it locks in 1.5seconds and am still tuning it to try to get it down to 1 second without getting to crazy on the numbers. I thought it weird it is using that table instead of just Ramp.
