The timing drop between gears definitely works, it is just too late for the shift, as in it drops the timing after the gearbox has changed. It makes for a weird power drop after the shift. We zeroed it all out in the end. It is understandable when you think about it, as the Fcon has no idea what the gearbox is doing, so it must work off the revs dropping or something.
I changed to the Nulon fluid in mine, dropping the dextron III that Kewish put in there after the build. Surprising how much firmer it shifts, perhaps the Nulon is thinner filling the accumulators quicker? It positively thumps into second and third now causing all wheel chirps.
