James your wrong. Jet Tech is John. MaxJet has been out of business and causing these same questions for a couple years now. People sell Maxjet units on ebay and people have no way of turning them on without locking the code. They are nothing but a paper weight now
I would contact these guys and see if they can help you. It looks like they are still trying to sell them. Not sure how without locking code. If you find out please let me know. I have one sitting in the tool box as i wont try and scam a fellow racer into paper weight….
