Meticulous Mouse For The Mule

Probably one of the more knowledgeable EFI calibration tuners in the nation, Dave Henninger (left), runs the dyno at Wheel to Wheel with Kurt Urban (right). He calibrates every EFI motor that rolls through the shop (usually one a day), so his skills are flat-out scary. Just wish he was your friend! His basic attack is to first drop a "best-guess" calibration (from literally hundreds he has created) into the EFI controller (which Wheel to Wheel can email for a reasonable price). Then tune the engine based upon the O2 sensor reading of the air/fuel ratio, ignition timing, and manifold pressure at various rpm for maximum power and efficiency. The refinement of the calibration on the dyno is mainly for power production. Once the engine is in the vehicle, the "cal" is tuned for optimum driveability (startup/warmup, idle, cruise, accel/decel, etc.) with two people at the controls (one driving the car and another running the laptop computer). I have used this type of EFI on the last few cars I've built and know I couldn't go back to a carbureted vehicle--they are so nice once you get them dialed in. Carbs do make great power, however, and do so at the right price! View Related Article
