The supported vehicles page has an asterisk on the 2000 Durango and says that some models have the NGC1 ecu that isn't supported, but I can not find anything that tells me how to know which one I have. I swapped a nv3500 maunal trans in to a 2000 Durango R/T 5.9, and the ignition timing advance is being cut to 0* on acceleration. I believe the ecu is trying to "save" the transmission that it thinks is slipping because the gear ratios are different, but I don't want to spend the money on the tuner if it won't even work for my ecu. Is there some way to tell what ecu is what? Thanks
