I went to Zcontrol.com and downloaded Mike's GUI for translating the Z ecu code maps. Lots of helpful information if you want to learn how to tune your own ecu. I registered on the bulletin board for ECU tuning. No need to buy JWT ecu which is huge rip. Thanks to people like Mike and Ashe who have cracked the ecu code to make it easier to read for the layman instead of reading the Hex codes. Too bad this wasn't around 5 years ago. JWT has already made his $$$ off of me and others.
