Electronic Dash
Using a laptop computer and the Hondata interface box, the user has the ability to pull up an electronic dash that shows all the engine vitals. The electronic dash views all ECU sensor inputs and outputs. This can be used to either view sensor inputs and outputs for tuning purposes or it can be used as a trouble shooting device by checking correct voltage inputs and outputs.
Programming on the fly is...
Programming on the fly is possible via a laptop and an emulator. Once a finished map is acquired, the PROM can be burnt with an EPROM programmer.
The Hondata shift light is...
The Hondata shift light is a high intensity LED and in Stage II trim, it can be set by going through the program sequence with a button provided with the interface box. Holding the rpm at the desired peak rpm and tapping the brake pedal programs the light.
The Stage IV Hondata unit is also equipped with datalogging capabilities galore. Since the factory sensors provide the engine information for fuel and timing parameters, Hondata decided to use this information for data logging purposes. The factory sensors deliver voltage signals to the ECU and the Hondata ECU converts the signals into a readable output (turning voltage signals into temperature and pressure readings). Not only is the unit able to record engine parameters, it is also able to read vehicle speed and gear changes through the OE speed sensor. A total of 48 channels of information can be sampled. The user-friendly software allows the tuner to scroll through the different channels and select what kind of data they want recorded, based on the engine's sensor readings. Sampling varies on the number of channels used, but record time is 6 hours. For precision diagnosing, the recorded information can be zoomed in or out for specific analysis.
Hondata basically took the factory ECU, which has a processor in OE trim and beefed it up with datalogging capabilities and the power to change fuel and timing curves. Eliminating the need to rewire a harness to use a stand-alone ECU and simplifying the programming in the ECU enables Hondata to sell the unit at a very low price. Hondata is also willing to do the modifications needed to get the programming started.
