As some of you may know, I converted my 97 F-350 with a 460 from bank-to-bank EFI to sequential EFI by making a wireharness and wiring in some other sensors so I could use an AEM full standalone ECU on my speed density setup (saved me from having to convert to MAF)




Well I got it running and took it to the dyno. I don't have pics and vids cause the buddy I went with used his phone and for some reason we can't get his sd card mounted to the computer so those will come later, for now I do have the graphs though:

First is 203HP and 321Torque
Second run I added about 4 degrees of timing and made 210HP and 329Torque
Third run I added 8* down low (went from 19* @600rpm to 28* @ 600rpm, then calculated over to 3500 where I'm running 35*. I kept it at 35* total as a previous with an added 2* didn't increase it at all) This is when I made 207HP and 341 Torque. Adding any more timing didn't help power so I backed it off to where it was and left it. AFR's were around 12.8 - 12.9 consistently. Stock cams, stock heads, stock headers, cat still installed and a drop in K&N air filter

 

Isn't that on ford 460 7.5L

9 mpg to 14 mpg is HUGE IMPROVE.


Would it able work on Ford 5.8L or 5.4L

How much for that AEM ECU cost? I read some internet like that cost nearby thousands dollars for ecu with wiring kit.

 

Yes it is on a 7.5 460. It would work on anything if you wire it up correctly. The aem ecu is normally 1600....i got an excellent deal on ebay for 750. Keep your eyes open on ebay/forums for the ecu....you'll need the 30-1400 unit. As for the wiring harness, i couldn't find one to match the specific application i was wanting to go with so that's why just i made it. Cost 50 bucks from the junk yard all in all this entire setup cost me about 800.

 

Whats a good but mild cam for an EFI 460 that wouldn't require any valvetrain upgrades?
