Holley tech support and MY experiances
The Black heart system is mostly conversion parts, no EFI stuff. They offer engine mounts, exhaust, trans cross members etc., for trucks and other platforms. I'm using an E38 and T42 OE ECM and trans controller with a BP Automotive harness....

T,
Do you have a build thread anywhere for the pick up? I know your in texas and will represent.
T,
Ron T, from Holley just called...drum roll....ecu is toast. N because its nothing we did(i guess they can tell if you fried it), he s pushing a new one under warranty for me. I ll have it in 2days!
Despite the rough couple of days going thru circles with the first few tech support guys, Ron T, is the guy to talk to. Him and Holley totally stepped up and took care of thier faulty product, with a very respectable turn around time from them recieving the ecu. Even during Covid 19. Despite buying the ecu bnib 2+ yrs ago and 2nd hand, they still replacing it. That is unheard of in my industry with service parts. Even my engine builder says that rarely happens in the aftermarket automotive sector.
I had to call Holley back in January and if I called at the "right time", I could get through in 15 minutes or so.
My problem was that the throttles wouldn't open more than 10%; I don't remember if the TPS Auto-Set failed too. In my case I had the brake switch on the wrong polarity and the ECM thought the brake was on. As a "safety" feature the Dominator limits throttle to 10% when the brake is on. (So no brake torquing and no burnouts!) I was sheepishly told that "some people" remove the brake pedal signal to the ECM to disable this "feature".

fwiw as much trouble as I had with my holley (bad wiring harness) i'm so blown away by all the features and the configurability of the tables and I/O's that I have bought a second termi x for my DD. sold off all my HPT and stock PCM tuning equipment.
got a spare termi x max computer on hand in case one takes a crap

Right now I have 2x Dominators and 2X HP ECU's and harnesses, 2x 7" screens and one 12" and harnesses. Before they were so popular I used to find them really cheap. I've bought and sold quite a few. Now it seems that enough people want them that the deals just aren't there like they were. The last one I picked up in February on E-bay. Complete avenger efi system (uses HP ECU) for $350.
all of this has been at the transmission end.
p.s its the same harness for 60/80e they just change the tune.
