After consulting with several local engine calibrators, one piece of advice was consistently offered: “Use your data.” They all said it and re-said it. Victor Chichester, from Chichester’s Tuning, and Howard Tanner, from Redline Motorsports, both suggested the engine team invest some time and money into upgrading their data acquisition methods on the Dyno.
As a result we purchased a four port analog input module from Dynojet. This has allowed us to log: horse power, torque, MAP, O2, all versus RPM in WinPep7. This one upgrade has greatly increased the efficiency of our calibrating efforts. Logging this data simultaneously during a transient run allows the operator to quickly interpret the information, and in turn put less wear on the vehicle and all our equipment. The first two runs with the new dataq tools are shown above. Below are some screen shots of the ECU software and WinPep7 control screen.

There is still much to improve but the team is making progress in a positive direction.
