Hondata – Honda Civic Type R
Over the last week we have been custom remapping a Honda Civic Type R. Now most vehicle that we custom remap are mapped by connecting to the OBD port or by removing the ECU and reading the cars files on the bench. But the Honda is a different kettle of fish and on some models we can’t do that so we have to use Hondata.
A Hondata system consists of additional components which are added to the standard ECU to allow the ECU to use a Hondata program (this modification is normally done by a dealer). An interface box is then connected to the ECU which contains circuitry for data logging, stores rev limits and interfaces to switches in the vehicle. Optionally a clutch switch, push button and data logging cable may be installed. Collectively all this is known as a Hondata system.
Hondata systems modify the standard Honda engine computers (ECUs), adding features and expanding the capabilities of the stock ECU.
So now we know the basics around Hondata 🙂
With the Civic being run on the dyno whilst we custom remap the ECU we are able to data log the fuelling, revs etc. This allows us to improve the performance in the safety of the workshop. With the remap written and tested on the rolling road we take the Type R out for a road test before handing the car over to the customer for their own test drive.
With the simple modifications of a cone air filter and decat we where able to achieve these fantastic results and the feedback from the customer was brilliant.
