Hi All,
I purchased a stolen/recovered Australian 2020 CBR650R, mainly for use as a track bike.
No keys, or antennae for the HISS, so the ECU was useless.
All the Australian CBR650R’s are LAMS restricted to about 40 hp, I needed to get rid of that too.
Option 1 – buy a second-hand ECU, antennae and key/ lock set to fix the HISS, then remove the intake restrictions, then get it tuned. This option was the safest but was going to cost about the same as the bike purchase cost = $2000 ish
Option 2 – take a risk and buy a USA ECU – these don’t have HISS and aren’t restricted so potentially fix both problems. Downside was the risk it wouldn’t work. Cost about $400.
I chose option 2, and it worked👍👍
ECU details were:
Australian ECU – Keihin 38770-MKN-U11 B183-100630 D2MKNU1A
USA ECU – Keihin 38770-MKN-L32 B370-100288 D2MKNL3A
Wiring changes required were all at the ECU:
Remove pin A5 (Yellow/red wire) for VCC1
Remove pin A28 (Green/Yellow wire) for SG Hiss
Remove pin B11 (Blue wire) for IMOAU
Run switched 12v power to pin B11 (Pink). I took the supply for this from the (Black/White wire) at the test connector.
I opened up the intake restrictions on the original trumpets, but I will replace them with the proper units now that I have it running.
I’ve only ridden it about 1 km since the changes, but it
Runs
All dash functions work
TCS works
ABS works
Has plenty of power
Happy days
