What moron thought of that when SEFI had been around for years when they built that truck in 95)
Seriously.

franz you hit the bullseye, i'd love the name of that moron who brain-waved bank fire. my bronco sits there idling in park, and the gas guage drops the same rate as going down the highway/hill/sidewind. we can slow down to 40mph our fool heads off, it ain't gonna help. might as well drive to the floor 100mph everywhere. ford should GIVE us the motorsport MAF kit, install it free, and cut us all a cheque to compensate for the extra gas we had to guzzle all these years. yeah sure. throttle response and that annoying hang time (89's bad, but my 92's better). i'm not looking for more hp, just much quicker t-r, speed density efi makes my 302 feel like that gutless/choppy 350 in a 77 blazer i once had. i wished we could re-create the feel of the old 289's or early windsors that RPM'd up AND down very quick. i badly miss that, as well as the smooth growly sound they made. those chevy baised magazines don't much mention that part when it makes it so much nicer to drive. oh well hope we can get some satisfaction here. glad to see someone's trying.

I have a 351 with a E4OD and was looking into all the MAF conversion's for more power. It was just a clogged cat. Feels like a new truck now. If for some stupid reason I decide to put a built motor in so I can destroy my 8.8 and E4OD then I guess I will need MAF. Do they even make a stall converter for E4ODs ?

I hope there is someone in this world that appreciates your arrogant attitude.

I would definitely be interested in this article, I am planning to convert a 1990 F350 351W, however I read that someone had posted earlier that a 351W won't run as well with a 302 computer over 4000 rpm due to the fact that it leans out, why would it lean out, if the MAF is directly measuring the airflow, wouldn't the computer sense the lean condition and richen the fuel? Since the 351w and 302 are using the same heads, etc i wouldn't think there would be much difference between them.

And what do we see? Speed Density according to Gacknar gives you better throttle response. He goes on to say that MAF ages better than SD and if you convert an older truck (engine;sensors) to MAF from SD you may see a slight performance increase based on the age factor.
Well, my whole world is crumbling around me now and I am seriously doubting my ways now. And of course an apology to the bank firing designer although that approach still irks me.

For those looking to go with an aftermarket, plug-n-play kit;
PMAS/Flowmanagment Unlimited just released mass air conversion kits for E4OD and non-E40d trucks. The base E4OD kit utilizes an EEC-4 Mustang ECU, Bauman transmission controller and adapter harness (EEC and air meter not included). They have other options that include the air meter, air filter and EEC as well.
