Ryan,

As always you have some amazing knowledge! Question: would it not be easier to use an older ecu from that gen dodge? When you say the converter is turned on and off are you talking about the overdrive or something else? I still have the 1991 Dodge ECU from the donor truck I could use, that is if it talks to the trans or not.
