I have now tested quite a lot of diagnostic software but PCHUD is still the only one which operates correctly.
In an earlier post i mentioned that PCHUD seemed unable to clear fault codes. This is still the case, i have been unable to figure out why.
Fortunatley i have found a russian diagnostic program that will.
This is useful because if you leave your ignition on for 60 seconds without starting your engine the MIL light on the RX3 will start to flash historic fault codes even after the initial fault is fixed.
This software will allow you to start with a clean slate.
The software will clear all fault codes but if you have an existing fault this will return after switching your ignition off and then back on again.
Here it is

instructions
--------------
Install the program, locate where the program has installed and replace the OpenDiag.exe with the one in the katflap folder.
I have partially translated it to make it useable.
Getting It Up & Running
-------------------------------
plug in your cable in to the bike and laptop
run program
select adapter K-line
settings (f3)
select port or run "find adapter" then "ok"
select ECU (F2)
double click M74 , as shown in pic below
select Errors tab
Reset errors button then "ok"
Job done!
(All though i've not had any problems, any software that pokes around your ECU could cause damage, so please remember
use at your own risk !)
Am I connected ?
--------------------
within 30 seconds of doing the above process data will be seen here
or here if you run the equipment definition (f1)
Can't get connected ?
-------------------------
try using method 2 then press "tuning initialization" or enter "17" in the "TiniL/TiniH box.
(I had to use method 2 on one laptop but on a different laptop method 1 was fine
)
