Supply/parts issues? Not uncommon these days, even for Hondata I guess.
I've only installed that Hondata jumper cable once. Total PITA for the upper connector.
I often wondered if one could just splice into 2 Canbus wires in the green connector.
Then find a wrecked TSX and pull off 2 OBDII pins/pigtails and use that at the OBDII end.
Worth a shot if you have strong electrical skills.
Your location shows Croatia. There are several TSX/Euro Accord tuners in Eastern Europe.
Little Bo and another recent member also posted up.
These folks can flash a 2004-06 ECU without the Hondata CANbus adapter, without Hondata FlashPro and without a 2007-08 ECU.
Worth researching before spending a ton of cash on Hondata FlashPro.
