Ive ‘been around the Honda block a few times’ too. Im not completely stupid (not saying your calling me stupid), I just dont know the area too well when it comes to shops, tuners, etc. Ive built many Honda engines before, and Ive dont massive amounts of work to my cars, and friends cars. I just dont know the area when it comes to the ‘car scene’. Thats all.
But to answer your question, yes. You can get a used Hondata setup, but you still have to pay for the software license. Hondata is stupid expensive and a rip-off IMO, so Im staying away from it.
