Converted 1997 F-350 7.5 460 to Sequential EFI - Dyno Graphs Inside
#16
If I hadn't already started acquiring my stuff for a conversion, I probably would have looked at AEM, I looked at a bunch of aftermarket setups. My major hangup on them was transmission control. I am going to EFI primarily to use an E4OD in place of the C6. I did acquire a 93 SD SEFI computer with E4OD control but after talking with a number of people found that SD doesn't tolerate much cam change. It causes the same issues we used to see with lumpy cams that had low vacuum at idle.
I plan on seeing if mine will go 16:1 or leaner at cruise, the old 390 2V engines in the LTDs would cruise at 19:1 or leaner (they would peg an AFR meter on the lean side). At least I don't have to worry about Cats on mine.

Not that I could determine. Everything I found required another stand alone transmission controller. That gets expensive fast. One of the issues I found is the E4OD is different electronically than the AODE or 4R70W. As a result, the pouplar ECMS (A9L and similar) will not operate it. Only the truck computers, 5.0L or 5.8L with E4OD have the circuits for this. I am going to be using a WAY1 box which uses the VEX1 strategy. It is a 5.0L Bronco unit.

Yes it does. You would just have to use the 30-1401 unit instead of the 30-1400 like I did. The only difference between the two is that the 1400 is setup for a standard transmission while the 1401 is setup for auto transmission controls. Like I've said before, this is a STANDALONE unit, it can do ANYTHING you want it to!

Jonbar, this was a 68 or 69 LTD with the 390 2V engine at a friend's shop just up the road from mine. He is a Chevy guy, and was showing me how efficient Ford's intake design was. He and I had staion wagons at the time for our families and were comparing notes. His was a Pontiac LeMans into which he had istalled a 327 250hp and Powerglide, 3:08 gear rear end and dual exhausts, mine was a 1970 1/2 Falcon with a 302 that I had installed 1965 289 4V heads and intake on, 351W exhaust manifolds and dual exhausts 3:00 gear. Around town I could kill him on fuel economy, but highway, they were real close due to his Quadrajet vs. my Holley. I finally got up to his level when I put a 1974 California 460 Carter Thermoquad on the 302. I know you can't do that level of lean mixture with EGR or catalyst as it just won't work. The catalyst needs that narrow range the O2 sensor wirks in.

Funny you ask...someone on a different forum asked the exact same question.
About 6 months before it was stolen I decided to sell it, and since I was going to sell it, I converted it back to stock. That's why I still have the AEM with all the wiring and sensor.

I paid $750 for the AEM 30-1400 ECU, (still has my dyno tune programmed on it) $50 for the wiring harness from the junk yard, and had a Honda map sensor lying around (that you could have). I kept the instructions in the glove box but obviously they got stolen with the pickup so unfortunately I no longer have them but I could walk you through the install from what I remember. Make me a REASONABLE offer and I'd consider selling.
