Well..I'm trying to keep up with some of the electronics found on newer cars to keep the Supra ahead of the game.
Many of the new cars have launch control. Basically, you mash the pedal, it hold the RPMS to a preset level, release clutch/brake and zoooommmm...away you go.
But the device on my car is different. Whereas a launch control is just holds a soft rev limit, an anti-lag is designed to do that PLUS make boost. It does this by looking at the crank angle sensor for TDC and retarding timing. The resulting explosive gases go through the manifold into the turbo causing it to spool at low RPMS. WRC Rally cars use this (that's all the popping and farting you hear as they blast by), but they use it while driving (for low RPMS/instant boost and take it one step further by having an extra couple of fuel injectors just for this purpose.
It's pretty impressive. I have it tied into my brake pedal circuit. So I just brake torque, it holds RPMS at 3000-3200 RPM, it builds boost instantly then when I release the brake it goes to my normal RPM limit. Very cool.
Here's the vid. Enjoy.
