|An AEM Wideband UEGO, Real Time, Air Fuel Ratio Gauge and Bosch wideband sensor were installed to help with tunng.
Once the EMS and Wideband were installed Mitchell Pederson of MP Tuning began the tuning process setting up air/fuel, ignition, cam angle tables and VTEC crossover point for the Honda K24 Power plant running 91 Octane pump gas, on the AEM Mustang Dyno. [Mitch is a former AEM EMS engineer and highly regarded industry tuner, his clients include among others Rhys Millen and Conrad Grunewald.]
|The car was strapped down on AEM’s Mustang Chassis dyno. The Mustang can load the engine in steady state conditions making it better for tuning than an inertial dyno.
Once the tuning was complete, the Acura was showing 195Hp and 155Tq on the AEM Mustang Dyno which is known in the industry as “The Heart Breaker” Dyno. Maximum rev limit had been set at 7600rpm. VTEC crossover point remained at 5000rpm but the transition had been smoothed out and part throttle response from the drive by wire system had been fine tuned. It was noted at this point that at high rpm the engine showed a slight lack of intake manifold vacuum.

As APD had the cams and EMS installed prior to the tune and dyno sessions on the Mustang and as all dynos read differently there was no base line data on the AEM dyno to effectively gauge performance increases, so the next stop for the Acura was the Official MotoIQ Impound dyno at Road Race Engineering in Santa Fe Springs, CA to quantify any increase in performance.

Mike Welch of Road race Engineering had done the original dyno certification for the APD Acura at the MPTCC, Auto Club Speedway event in June and had the baseline performance numbers for the Honda K Series power plant prior to this round of modifications.
|Once the tuning was complete, the Acura was showing 195Hp and 155Tq on the AEM’s super conservative Mustang Dyno. Now it was time to verify the power on the official MPTCC Dyno at Road Race Engineering.

The APD Acura showed an amazing gain of approximately 39 Horsepower and 23 Foot Lbs of torque! Up from 201hp and 161tq to 240hp and 185tq. A 25% increase in HP and 20% increase in TQ. According to the dyno data the increase was uniform throughout the entire power band!
