Finally a controller for the 42RE on the market...anyone know anything about it?

Is there something different about the 42RE as compared to a 46, 47, or 48? Stand-alone controllers for those others have existed probably more than 10 years. Lots of guys use these for Cummins swaps with 47RE or 48RE transmissions. There’s a ton of history out there on the variety of controllers. I think Holley EFI can even control one now. It might be less revolutionary than you think.

I've seen controllers for the 46, 47, and 48 in the past...but never a controller that stated it could be used with the 42. If they were compatible you would think they would list that and increase the market for their product. In addition, this same company used to make two older models, one that they said was compatible with the 46, and one with the 48. Stands to reason if they released a new controller that works with all of them that there are differences. I don't know what the differences are personally.

Same situation with the diesel controllers. Been out there a long time. Why wouldn 't they work for gas too? There are differences clearly, otherwise people would have been using them for gas. Not sure why we're chasing the rabbit hole on it, but happy to do it. I'll look into the holley EFI thing you mentioned, as I'm already planning on getting a sniper
