I find out today that the Greddy E-manage (the blue unit) is being discontinued. I heard that people have had issues running the 1JZ on the E-manage Ultimate unit. Does anybody know for sure if the E-manage Ulitimate runs just as well or better on the 1JZ as the run of the mill E-manage?!? If not, I just might buy one of the blue units before they sell out, to be sure that I have a viable option for my future plans.
