Finally, the instruction you’ve been waiting for is done.  Check out our latest video covering the modern GM Direct Injection engines with their torque based electronic throttle control.  LT1, LT4, LT5, L83, they all run the new DI controls featuring completely new injector, fuel pump, and throttle control systems.  Don’t worry, we break it down in plain English and show some practical examples (using four-digit horsepower!) of how you can learn to calibrate your own projects with confidence on this new system.  Don’t be intimidated.  You might be surprised how well these systems can work if you take the time to tune them properly.  The video is available NOW from our partners at Detroit Technical Media.
