Bare with me guys, as I am tryign to figure the f-150 stuff out....


My truck is a 94 maf 302, with the 4r70w.. Is there any benfit swappign to a mustang computer? I knwo the 4r70w is computer controlled, and the 89-93 maf eec's won't work. But what about a 94-95 computer? I am not looking to make it fast, just wanting little more pep.


Also any one know cam specs for the truck 302? Have been kicking the idea of dropping an exploer motor in and juts use the truck intake?

well....no EEC-IV had a 4R70W, just the AODE...the earlier Stang EECs such as the A9L, worked great with the 5.0 cars, you are better off getting an SCT chip.

As for the Exploder motor, they are about the most sought after due to their lower manifold and heads...but, if you want to do some work and really get some fantabulous EEC control with the 4R70W, you could swap over all of the EEC related stuff and run an EEC-V.

No EEC4 came with the 4r70w, but we put one in the 88 'Stang. It has a manual valve body, trans brake and a switch to turn on OD. I agree on getting the SCT chip however.

obusnizzle

nope....you are wrong. 93-95 Lincoln Mk8 had one......

and the only 94 MY Fords with a 4R70W and EEC5 were the thunderbirds and crown vics.

and if he does have a 94 F150 with a 302 and 4R70W, it doesnt have an EEC5, because the Exploder with the 5.0L had an EEC5, while the mustang didnt.

Ummm your own post just said the EE4 didn't have one and I was agreeing with you. After looking back we were both wrong. 1994 and later vehicles with four speed automatic transmissions will all have an Overdrive Cancel Switch and a P-R-N-OD-2-1 shifter pattern, but may have either an E4OD or a 4R70W transmission. All 4.2L, 4.6L and some 5.0L engines use the 4R70W transmission
If a 1989-1993 truck has an Overdrive Cancel Switch and a P-R-N-OD-2-1 shifter pattern, then it is equipped with an E4OD transmission. With the possible exception of some 4R70W equipped 1993 E-150 vans with 5.0L SFI engines (The existence of a 1993 4R70W van is unsubstantiated).

I typoed the first statement, the mustang never had an EEC4 and 4R70W.

Isn't the Aode and 4r70w basically the same trans,, electronicly shifted?? But the 4r70w has the wide ratio plantetary gear set. I know the v-8 mustang didn't the 4r70w until the mod motor era..

obusnizzle

yes and no. The 4R70W does have the wide ratios, but depending on the application, the valvebodies are not the same. Here is a very good thesis on the differences, it was written by a Powertrain engineer named Jerry Wroblewski. He started a little known company called SCT.
