Flashpro for Canadian R18's ECU Compatability

Hello Guys,

As per suggestion by Reximus, I am going to try to start a thread where people who have successfully had a USD ECU installed into their CAD R18 Civic will post the year of their car, old (CAD) ECU # (If you know it) and new (USD) ECU #. Also if you had to purchase anything extra to make the swap work please feel free to post that as well.

Note: According to Hondata, "With early vehicles the gauge control module (tachometer) must be replaced in order to reprogram the immobilizer. See Honda TSB 06-011 and TSB 06-008. There is a VIN number range this applies to (early 06 vehicles)."


Hopefully this will take a lot of the thread jumping and guess work that goes on with purchasing the appropriate ECU! :dancing:

Jfigs11: 2007 MT DX-G, Coupe
Previous ECU: RNA-C07
USD ECU: RNA-A07

Reximus: 2009 Manual DX-G Sedan
USD ECU: RNA-A12
RNA-A14 did NOT work for me, dealership could not program.

Banach: 2008 Honda Civic DX-G
USD ECU: RNA-A13

Coffeecat: 2009 Honda Civic DX
USD ECU: RNA-A13

Sleepy: 2006 Ex Coupe
Old ECU: RNA-C54
USD ECU: RNA-A63
Had to replace gauge cluster, rewritable gauge cluster part # is 78200-SVA-C02
"do not buy a used cluster as they are not rewritable"

gonna scour the thread and find more :)
can you tell us what year and model your car is?
we should also note according to Hondata:

"With early vehicles the gauge control module (tachometer) must be replaced in order to reprogram the immobilizer. See Honda TSB 06-011 and TSB 06-008.

There is a VIN number range this applies to (early 06 vehicles)."
found another. banach's R18 is 2008 Honda Civic DX-G and he has ECU A13

also coffeecat has 2009 dx with A13
im really liking my chances now that i see how many other people made A13 work!
when's the big day?
oh wow that ECU # looks relatively new haha. to the list you go!
flashpro is barely a dent on the amount on what i spent on my car haha
So, good news today! just got my car back from Honda and the swap was a success!

old ECU #RNA - C43

new USDM ECU #RNA - A13

swap only cost me $95 and it took them no time at all... they could not modify my base maps to help me from running lean until i get my E-TUNE but thats fine.
Congrats brother. Lucky on the price :p
lucas has 2010 manual trans DX-G sedan btw
i think the cluster issue only exists if you have a 2006 cluster to begin with
