Ok, bit of a thread necro. After hours of studying and playing with circuts, we finally have a design that we feel is going to work. Here is a little teaser.
370z RLTC
We eventually turned up the launch control RPM and you could really hear the RL kicking in, and of course I did not record it properly... it will be on the next video lol
I still want a bit more real world testing on this before I say its ready to go, but the future looks bright.
