For anyone wishing to try the TuneECU software, but unwilling to build the custom cable, I'll be building several that will be available to buy. Cost will be $30 plus USPS shipping. I don't make money on these, just want to help the TuneECU project take hold. This will also include the ODB-II cable as pictured below.
If you're interested please send me a PM with your shipping address. I'll respond with the total price.
