What does hondata ecu do

Because it is best to tune the ECU using a dyno and wide band lambda meter, it usually works out best to get a dealer or someone with tuning experience and the equipment to tune the ECU for you.

If you want to tune Hondata for other people, see dealer requirements. The dealer's installation and dyno time is not included in this price.

Outputs include a shift light and a DB9 serial port for use with datalogging. It's very easy to duplicate all the guts of a Hondata-modified ECU with a handful of off-the-shelf parts and an EPROM burner, which could potentially make it very easy and cheap to duplicate an expensive Hondata system.

However, the Hondata engineers were smart enough and had enough business sense to closely couple the ECU functions to the microcontroller in the interface box, so the ECU won't work to its full potential without the microcontroller. And since it's pretty much impossible to extract code from a properly configured PIC microcontroller, they're spared the headache of having any schmoe with an EPROM burner be able to duplicate their work.

In case you're wondering what happens without an interface box, if you unplug the interface box from a Hondata ECU, it enters "limp home" mode.
