I have an ECUTEK cable and dongle. For those new to ECUTEK, this will require a license. Once you apply your license to you ECU, you can use the ECUTEK to datalog, flash tunes and much more. The kit will come with a OBD2 port extension harness. Asking $250.

I also have my stock ECU from my 2013 BRZ w/ manual. I will be replacing this ECU with a Haltech Elite 1500 for my K24 swap, so I no longer need it. It has an ECUTEK license. If the ECU is compatible with your car then you could use the ECU and not have to buy a ECUTEK license. See the article below for details. Changing the VIN on the ECU or modifying the firmware may delete the ECUTEK license, so read the article below and understand if this solution saves you money. The license is north of $300. I am asking $100.
