Going to respectfully disagree with you on this point ... if you look at the supported controllers from the EFILive home page, it will become evident they support nearly every V8 engine platform from 1998 onward.

They do have limited support for 4 and 6 cylinder engines ... but again, no offense intended, most Hot Rod builds will use a V8 engine.

I have never worked with 4 or 6 cylinder engines, and have no plans to do so.

EFILive or Tunercat are more user friendly - as both allow users to define / create their own parameters based on individual need. EFILive does this via user defined CAX files, Tunercat allows users to modify the VDF files.

HPT does not allow for any such user input / customization.

As Jeff pointed out - EFILive affords the user the ability to make and save changes to a tune without having to license it - which allows for greater peer support among enthusiasts.

I own them all - HPT is my least favorite.

Just my opinion ...
