He may have sent you something other than .hex file. But it seems your doing fine with what you have. Your lucky you have a tuner available that can use TuneECU. There isn't one around me for hundreds of miles. I live in KC Mo. and I think the closest is Nashville.
RR 2010 with RamAir and Viking 3 into 1. Thank you for this informative post. Very helpful. I have loaded a tune from Paul, but it seems lean still. I would like to get this 20355 KN TORS.hex tune, but being a Newby I'm unsure where to access it. I would be grateful if I could be directed to the resource. Peter Gilbert, Blenheim New Zealand.
