78. Replay (Optional Feature)
The GEN3 ECU’s optional internal data logging capability is called “Replay”. Replay
eliminates the need to keep your PC in the car while going down the track. Replay is capable of
sampling fifty-two (52) channels of data, fifty (50) times per second!
In order to record data to the internal RAM, the Timer Enable pin, Pin A of the 4-way Boost
connector on the main wire harness
Boost_Connector_Pin_Out and the TPS threshold setting
must be met. A toggle switch should be wired between the 12 Volt source and the timer enable
pin to allow the replay function to be turned off. After a pass (with the ignition off) the data will
be maintained in the ECU’s internal RAM for 30 minutes. After thirty minutes the data will be
lost so it needs to be uploaded to a PC within this time. Once you’ve verified the data is good,
turn off the Timer Enable pin (via toggle switch) for the next logging event. Remember to turn
the toggle switch back on prior to staging the car.
Inside the “Replay” drop down there are three (3) submenus. Each submenu will be described in
the paragraphs below. To get to the Replay drop down screen, go to the main Tool Bar and left
click on Replay and the screen below will appear. Hold the left mouse down and drag it to the
desired input screen and release the mouse button.
79. Configure Replay
