grumpin Posted February 28, 2021 Share Posted February 28, 2021 A friend at church was telling me about these guys. Probably heard of them, but thought I’d put this here anyway. https://460efiguys.com/ Link to comment Share on other sites More sharing options...
fryntrz Posted February 28, 2021 Share Posted February 28, 2021 I have a pair of their swap mounts coming to replace the L&L rubber style. They look nice and robust, and the warranty is great. Obviously a more personal, hands on owner/operator shop - the response to an email inquiry and eventual order processing was slow, but they emailed and apologized about how busy they were. Which I can respect and appreciate. Link to comment Share on other sites More sharing options...

85lebaront2 Posted March 1, 2021 Share Posted March 1, 2021 Seem very responsive, my friend has called and talked to them. When I did mine they didn't exist and the bulk of the information I was finding was telling me to use a Mustang EEC-IV box with a piggy back tuner such as a Moates Quarterhorse or TwEECer in order to (a) change the firing order and (b) change injector size and © cylinder displacement. I still had to find an EEC-IV box that included the necessary circuits for an E4OD. I had finally found one from a Bronco 302 w/E4OD and was trying to find how to modify the transmission parameters as I really didn't want to be buzzing a 460 up like a 302 and I wanted to be able to keep the converter clutch on longer to keep the heat buildup down (the torque converter is where most of the heat buildup comes from). End result, while posing the questions on EEC-Tuner and TwEECer sites Adam Marrer (POPS Racing) contacted me and after some back and forth suggested that an EEC-V would be better as they can be reflashed as needed once the initial "crack" of the computer is done using a token. They (Core Tuning) use Binary Editor to write the code for the EEC. There was one glitch in the older release concerning the canister purge setup. The OBD-II systems which the EEC-V was designed for, use two different purge systems, the standard one with the solenoid purge valve and a later design with a Vapor Management Valve (VMV on diagrams). The CANP system needs a tank pressure sensor as it normally uses a small pump to pressurize the tank on initial start and if it does not see the pressure sensor and a rise in pressure, it sets a code. The VMV system uses a duty cycle solenoid valve to operate a diaphragm actuated purge valve and this feeds into a nipple on the PCV valve tube from the back of the plenum. The CA spec, MAF/SEFI 460s used this in 1996/97 trucks with an E4OD. I have installed tis on Darth and once the new engine is in, I will flash one of my EEC-V boxes with the changes including the VMV system. Biggest issue when doing a 460 to MAF/SEFI is finding a big enough MAF sensor, the 302 and 351 engines use an 80mm MAF, the 460s take a 90mm, but they are more common than you would expect, many mod motor vehicles use a 90mm MAF so othr than having to come up with an MAF/air filter combination that works, it isn't too bad.

I’m impressed with what you did Bill. Thats is cool. I really like how you’re manipulating that E4OD! I can’t or won’t justify putting an EFI on my truck. I sure would like it. The truck is the only carbed vehicle I own. I won’t put an E4OD in either. Maybe if I was younger and could crawl all around these trucks, or have a big shop with a lift. And of course, enough money to do it or have it done. I’ll keep driving it as is, it’s really running good! Link to comment Share on other sites More sharing options...

grumpin Posted March 2, 2021 Author Share Posted March 2, 2021 How old are you? I will be 75 in May, my late father did a head gasket on his Toyota Supra Turbo at 80. Not that old, but previous injuries have taken their toll. I should not have lived through one of the car wrecks I was in. I’ll be 60 soon. That’s great that your father did that. I did the head gaskets on the Xterra I now own about four years ago. That V6 in there is like the old saying of 10 pounds of manure in a 5 pound bag.

I think the EFI installation is for old guys. I'll be doing mine this winter and I'll then be 74. Link to comment Share on other sites More sharing options...

If you manage to get it done in the next three weeks I'm giving you a star and an extra cookie at nap time. Link to comment Share on other sites More sharing options...

You know I can't install a light bulb in three weeks. And I don't eat cookies at nap time. Cookies require coffee, and if I drink coffee just before a nap I'll have to get up in the middle of it to go to the bathroom. Link to comment Share on other sites More sharing options...
