How deep the study goes
We 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 us add functions the factory software never had, and not only change the numbers in its tables.
What we 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
Related controllers
The engine-only version of this ECU, used where there is no automatic gearbox to control, shares its program with this one and differs in calibration. We have mapped it and two other sibling controllers against our main platform. If your Honda is from the same period, ask us about it.
