How deep the study goes
I have catalogued all 1,884 functions in this controller's software and mapped the same functions across three sibling Honda controllers.
That depth is what lets me add functions the factory software never had, and not only change the numbers in its tables.
What I have built on it
- Boost control owned by the factory ECU, per gear and engine speed, with an electronic wastegate.
- 3-bar pressure sensor conversion and full speed-density fuelling.
- Boost reduction on knock and on a lean mixture, with a hard stop.
- ECO, NORMAL and EXTREME drive modes on factory buttons.
- Paddle shifting from the cruise stalk, and a torque cut for boosted gearchanges.
- Self-learning ignition timing and fuelling.
- Fault codes shown on the dash and cleared from the stalk.
The complete list with status is on the feature list.
Case studies
- A turbo Civic R18 that still runs on its factory ECU
- An electronic wastegate the factory ECU commands
- Fault codes on the dash, no scan tool needed

I have also mapped three sibling Honda controllers against this one. If your Honda is from the same period, ask me about it.
Have a car the usual tools cannot touch?
Tell me the car, the engine, the gearbox and what you want it to do. I reply to every serious enquiry.
