Honda-Tech needs some sort of search ability, where you can search through old threads.......

There might also be a problem if your Fuse Box is from a canadian car....

If your car is made in Canada then your fuse box won't have an ELD in it.

You will need to either wire an ELD into the fuse box(not sure if possible) or buy a fuse box with an ELD already in it. The only other thing I'm not sure about is if there is an existing plug(s) that connect to it on your canadian car. Try hooking up the jdm fuse box and let me know how that goes.

Code 20 might put your ECU in limp mode. In limp mode I dont think you can rev past 6500 or 7000 rpm. Does it throw any other codes?
