Hondata

i had a shop chip and tune my ecu about a year ago for a b16 swap, now i have rebuilt that motor myself and want to tune it myself. only problem is there is no usb connection on the s300 board or the ecu, there is a 4 pin connector on the ecu at cn2. i at first assumed that that was for the usb connection but that did not work, tell me what i need to do to get this thing connected to my laptop.

thank you for your help

Post a picture of what you have, as it sounds like you do not have an s300 and you may not even have a Hondata system. You may just have a socketed ECU.

i think that may be the case, but the ecu has an extra board in it and looks exactly like the picture of the s300. i will post a pic of it tomorrow and maybe someone can tell me what i have and how to access it
