Hondata Flashpro now working on AUDM Honda Civic FD's R18
With the recent success of Steve's R18 Turbocharged Civic FD running a Hondata Flashpro, it now makes a preferred option for ECU management for other Honda Civic FD owners
The Hondata Flashpro conversion on Steve's car wasn't all that straight forward. There was a lot of misconception of information out on the web and especially with cars using it in Canada. Reading and getting the right information wasn't all that easy. Some people said we might need to change the instrument cluster and immobilisers control unit etc etc. So im creating this thread to give you guys the facts!!
The BYP Team took the gamble and an order a used US R18 ECU (You will need the right code ending ECU to work with the US Hondata Flashpro). The risk with the US ECU is making sure all the pinout was the same with the Australian vehicles and with the help with a few people, we were able to double check the ECU pin for pin. To our surprised 95% of the pin were identical, there was some pins that were extra on the AUS ECU and vice versa for the US ECU. But these extra or missing pins weren't detrimental to the operation of the car
The first important step was to get the US ECU working on the FD. With assistance from our good mate from Honda, with his trusty Honda tool, we were to successfully reprogram the immobiliser and get the ECU to communicate WITHOUT the need to change anything else. Don't be scare when the engine light is on when you start the car with the US ECU. The US cars runs extra EVAP and emissions sensors which our Australian FD don't. With the use of the Hondata Flashpro, we were able to remove the engine light by disabling these features.
Since Steve's Civic FD was a 2010 model, Honda decided not run an Oil Pressure sensor on the Vtec solenoid. Consequently, since the US ECU was an 2006, this sensor was still implemented. As a result, the check engine light was still on showing this code.
There is two way around this, either to purchase a new Oil Pressure sensor from Honda or get an vtec solenoid with this oil pressure sensor. Due to time constraints, the BYP Team opted to find a second hand vtec solenoid from an 2006 Civic FD. The sensor also needed to be wired in. (3 wires - 5v power, signal and ground). After its successfully wired in, the check engine light disappeared. The US ECU with the Flashpro is NOW working 100%
Hondata Flashpro base calibration are good base to start from. It has all sorts of calibration for all type of modification, from bolton mods to TSI turbo set-up. Dyno tuning is HIGHLY RECOMMENDED
The car drives very well, idles like stock, smooth transition between RPM's.
I hope this thread will help other Australian FD owners in the near future with their builds. If your doing bolt-ons mods or a turbo kit conversion, I highly recommend you to consider the Hondata Flashpro as your preferred choice of ECU management
