2008 Challenger 6.1 swap input

The holley ecu and harness is my preference...but if you have access to the oem stuff for cheaper, no reason not to use it if u r set on the Chrysler trans. Ecu can be setup to just control the engine. Im just not a fan of all the work for a hemi swap, then with a Chrysler trans you have to have a toggle switch for od...and also do some rigging to get the lockup to work with the mopar trans...thats what led me to the Holley harness, which can control a 4Lx0e gm trans. So pick your evil...extra switches with a mopar trans, and extra bs for od, kickdown, and lockup...or a gm trans...or the big 'ol, big $, aftermarket od units...I picked the 4l70e...
