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:

I am going to the dealer on the 17th to have mine changed to an A13 I really hope it works, i need to get this care tuned ASAP its idling at 650 rpm running hella lean. I changed out the intake manifold, spaced the throttle body and put on a SRI, exhaust has megan header and downpipe then magnaflow line and muffler... ecu is so confused :S

[reximus]

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)."

Had to have gauge cluster replaced,not immoblizer as one dealer tried to get me to buy one. You do not need to buy one. As well do not buy a used cluster as they are not rewritable. I am going to call the dealership to get the part number of the rewritable cluster.

The Vin on the american ECU was (1HGFA16507L001773).

Hey sleepy thanks for the input, what was the ECU# that you swapped in?

Hey sleepy thanks for the input, what was the ECU# that you swapped in?

I will have to go check the Ecu itself. The rewritable gauge cluster part # is 78200-SVA-C02. I call the parts department where I ordered mine and got the info this morning.

ECU Part # 37820-RNA-A63 There was a second number not sure what it is for but this is it. 4750-105943

 

[reximus]

oh wow that ECU # looks relatively new haha. to the list you go!

 

[Sleepy]

I will try to find my old ECU# in the pile of stock parts I have collected and post up that number.

ooo I found it behind my desk at work.....lol

Old ECU# 37820-RNA-C54

 

[Jfigs11]

Ah perfect the list is growing!! Wish I had this list when I wanted to do the swap hahaha.
