well not quite true..the iic460 has "traction control" too..ONLY during launch where you can set the amount of wheel spin desired.
MY friend has the RL system in the Z. Very nice system. I was going to get it but I don't want to deal with all the wiring he had to go thru. Plus the Techtom is less than half the price granted it doesn't have full time traction control. It actually works out pretty good for me since I only want the 2 step launch and WOT shift.
