Bought a J-Spec ECU from Ryan. He was extremely pleasant to deal with, very prompt at replying to e-mails and got my package shipped out in good time too.
He even went out of his way to send the ECU to a different address for me so that I could get the ECU socketed and the CAPS done on the way. The guy who received it said it was one of the best ECUs he'd seen and didn't even need the CAPS doing. So it was a good buy obviously!
