stand alone ecm and wiring

[Old guy44]

Haven't been around for a while, I have been waiting for my ecm and loom. I do not know if I can mention the name of the crooks but they are in Ovid Michigan. I sent them my ecm and $1100.00 mid March and am still waiting They will not answer a phone call or e mail. I now find myself needing another ecm and stand alone loom. Is there someone out there that is REPUTABLE that I can contact. I am attempting to install an L83 and six speed auto into my '63 Catalina convertible, it was supposed to be ready for summer but.....................

Also is there an opinion on the variable displacement? This swap is primarily for fuel economy which is why I went for the direct Injection, if the specs don't lie it should be reasonably economical in stock trim. Should I get rid of all the variable displacement hardware while the engine is on the shop floor, eliminating a possible source of breakage, or keep it and the software that controls it? As stated I am looking for economy. The Indian runs great as it sits it just wants premium fuel at 12 MPG. Don't know about the rest of the country but premium in So. Cal is 4.25 to 4.50+.

Before anyone asks I have gone to an HEI distributor, rebuilt and rejetted the original carb and have tried two different throttle body injections, a modified 90's vintage GM and a Holley sniper. It does run the best on the sniper but mileage is the same. I swear that you could put this thing on a flat bed and carry it across town and it would be sucking fuel on the trip.

So I am back to the L83. I do not believe that the install will take more than a week if I can get the ecm and wiring so I know I can get it running.

I would be grateful for any advice you can offer.
