New Hemi's interchangeable with harness?

Hey guys,

How interchangable are the engines with the harness's? I have a 5.7 hotwire harness, can you use this for a 6.1 or even 6.4 hemi? Or are they different connections, and I assume different computers? Or can you reflashbe a 5.7 computer ? Not planning on it at the moment, just curious for down the track.

Call Chris at hotwire.........he would know more than anyone here, about their stuff.

With the Hotwire setup you need one of the Diablosport tuners to load the 6.1 tune into the 5.7 computer, not sure what the deal is with the 6.4 though. I think a couple of the sensors/connectors are different between the 5.7 and 6.1, pretty sure you can just use the 5.7 sensors in the 6.1 motor from what I have seen elsewhere.
