Product Information



This is for the K100 and installation into your ECU only (ECU not included).  When purchasing a Hondata K100 by mail order, please email us at for an order form to send to us with your ECU so that we can fit the K100 for you.  There is no additional charge for installation.  We have a very quick turnaround, ECUs received Monday to Thursday before 11am are usually processed and shipped back out the same day (excludes Bank Holidays).   

We regret we are unable to accept callers to our workshop for fitment of K100 unless the car is booked in for dyno tuning to be carried out here on our premises at the same time.

The Hondata K100 will shipped back with a stock calibration loaded back onto the ECU.  Please be aware that there is no USB interface so the customer is not able to download base maps, datalog, carry out diagnostics, use the Hondata Mobile app etc.  If these functions are required a Kpro4 should be purchased instead.

We do not recommend K100 for swap vehicles, if you have built a swap (e.g. K20 into a Lotus, K20 into an EK etc) then we recommend that you purchase the Kpro4 instead.


The only definitive way to get the most from any engine modifications you have made (such as air intake systems, exhaust systems, camshafts, supercharger, turbo etc) is to have the electronic control unit (ECU) in your car professionally tuned/mapped on a dyno with a Hondata engine management system. 

Hondata systems modify the standard Honda engine computers (ECUs), adding features and expanding the capabilities of the stock ECU. Vehicles with year of manufacture up to and including 2006 models require the ECU to be modified and in most cases hardware is added, for vehicles of years 2007 and onwards tuning takes place via an external programming interface. In all cases Hondata software is utilised in order to change the parameters/settings within the ECU (i.e. to tune the car).

So why use Hondata instead of one of the many standalone systems available on the market? The answer is very simple; nothing will run a Honda engine better than a Honda ECU, and the Hondata systems all leave the Honda ECU completely intact thereby retaining full reliability, full dash functionality etc.

The Hondata K100 is a system which converts the Honda factory ECU in the vehicles listed above into a reprogrammable engine management system. Once converted, the ECU can then be tuned (remapped) on a dyno by an authorised Hondata dealer to release the untapped power in your engine. All levels of modification can benefit from a K100 system, from a totally standard car, to a mildly modified setup, right through to the wildest supercharged, nitrous-injected or highly powerful turbo setup. The K100 system will give EXACTLY the same power gains as the KPro, however it does not have any of the additional functions such as data-logging, launch control, engine diagnostics etc.

• Fits inside the ECU
• Adjustment for different sized injectors, with overall fuel trim
• Configurable for any MAP sensor (to 5 Bar and above)
• TPS based table lookup for ITBs
• Engine protection from over boost
• Expanded fuel and ignition tables, both in rpm and load, to 60 lbs boost and 11,000 rpm (these are not the upper limits)
• Three multi-purpose outputs for nitrous control or similar
• PWM output for boost control

Notes: -

1. The K100 is NOT user-tunable and can only be tuned by an authorised Hondata dealer once it is fitted to the cars ECU.
2. The K100 is NOT an ECU, it is an engine management system that is fitted inside your existing ECU, you will need to send us your ECU for this to be professionally installed by us. 
3. If required, CPL Racing can supply used fully-tested ECUs, this may be favourable for customers that prefer to keep their original ECU unmodified or need an ECU supplied for an engine conversion/swap vehicle. Please email us for prices of used ECUs available.
4. Price quoted does not include tuning, for a tuning price please email us with details of your setup.
