I am in the middle of a 6.1 hemi/NAG1 trans swap. I need a harness (hotwire automotive)and a driveshaft.

It has me pondering going with a Holley Dominator EFI setup and a 4L80E transmission. The Holley EFI wont run the NAG1. Anyone here have experience with the holley set up or the trans swap? Any other EFI systems out there worth considering? I have looked at the Bigstuff 3. Looks extensive. Probably a bit more control than I need.
Seems like I noticed some guys running a system out of brazil???

All I see that the Dominator will run is the
GM trans.. I cant help being I'm running the
HP unit

Looks like they offer wiring harnesses for both early gen III and '08 and up Gen III hemis. The dominator EFI will also work with the Chrysler fly by wire gas pedal The VVT is not supported however. I don't need or want the VVT or MDS. I believe the other controllers I have heard about it Fuel Tech. But I see no indication they can control the transmission, GM or otherwise.

Efisource.com now has a transmission control unit for their gold box

Thanks for the heads up... looks like it is for the GM transmissions only at this point. I will keep it in mind if I dump the NAG1.

Check with Bill from Paramount Transmissions. I helped him with his twin turbo Jeep in the early days. He is one of the leading builders of Nag 1 trannies. The guy is a freakin' genius and designs a lot of his own parts. He might be able to steer you in the right direction.
