Steve, Here is the EC2 hex
file.im a little confused by the fact that your EC2 code is EC2-A1T but your engine is a Renesis. This code is for the Renesis. Also be aware that the EC2 was made in 3 versions. This is for the later version with the 5 pin programming ports near the chips. Let me know if you have an earlier type. Also note that the Configuration bits need to be manually set in MPLAB to use this code.
EM3 code to follow.
