Ok, you can get generic conveter cable and attach proper Honda DLC connector:

Pin-outs

-Black/white > +12V
-Orange/White > K-line
-Brown > SCS can jumper to flash error codes
-Green > ground

 

The ECU does not speak OBD2 language, but much, much older analogue serial K-line protocol. Similar to modem AT commands for those familiar with dial-up modems. Downloading flash image .BIN file takes 15-minutes @110 baud !!! 😛

Awesome, thanks a lot. Will get cable from amazon.ca and connector from aliexpress and see what happens 🙂

It's a basic USB/serial to TTL converter cable. Can build your own with instructions here: https://github.com/AlexKovalevich/HondaECU

 

Heck once you've reached that site, you might as well download all the software to edit maps and flash them to ECU yourself. He's got stock and modified .BIN files for download with 1st/2nd gear restrictions removed.

Ha, i see, definitely not basic for me 🙂 Thanks, that answers my question 🙂

 Stefan did my VFR with DCT. Work much more better right now. No restrictions on the 1,2 gears, smoother ride on low revs. I recommend.  Reflash was done remotely via internet and team viewer.

It looks like in order to do the remote flash you also need to buy a cable. Is it some special cable that I can only get from Stefan or i can get it somewhere else for cheap? The reason i'm asking is because it's pushing $90 if buying from Stefan.
