Technical help question for all you programing experts. I have two conversion projects. One using a 2011 3.0ltr 4JJ motor and another using a 2013 Colorado 2.8ltr Duamax motor. At some point soon I will need to get into the two ECU's to read/write error codes, disable non essential start-up features etc etc. I wont know exactly what until I get to this point. I am looking for an interface that will do both ECU's and would be great to hear from you if you have experience in this area. Happy to learn two pieces of software but would rather only one.
