Does Anybody Know The Benifits Of Going To Mass Air From Speed Density On 1995 Bronco 5.8 E4od 4 X 4?? If I Am Going To Add A Cold Air Kit, Cat Back And Maybe Shorty Headers Is It Worth To Convert. There Are Other Benifits Of Doing Conversion As Well Like Better Millage, Better Throttle Response. Also If I Went To Mass Air With Obd Ii From Obd Ii Will I Be Able To Use Obd Ii Scanners And Would Bronco Have Same Trouble Codes That A 1996 Or Newer Truck Have?? Just Trying To Figure If It Worth The Investment Going To Mass Air And Obd Ii. Thanks.

 

Better throttle response. More MPG . I have put them on 3 trucks. And think its worth it. But I used stock parts for truck parts . Other than you would have to get 351 maf ecm . You can get all parts needed for around $300.00 usually less. Thats what last 2 94 -95 F150 setups cost me with engine and fenderwell harness ,ecm ,airbox for maf,maF and air tubes as well as all new gaskets and o ring while I was at it. I just bought a whole 95 F150 302 4x4 for $400.00 for parts. If you stumble acrossed parts get them . But the MAF kits they have are way to much. $$$ good luck

 

u did install with e4od trans?? can u use obd II scanner to troubleshoot? i have a spare ecu from an old 96 bronco so i think i can use that?? can u give me a parts list and do u know where i can get detailed instrctions from?? also what are benifits over speed density?? thanks.

 

Yes my both trucks ( and new parts truck to. )have e40d and no its the old OBD 1 which ith 1 o2 and ease of use I prefer.
Do search there have been several posts hear and F-trucks as well as th Ford small block forum.
The Maf setup is sequential and none is batch. You will need injector harnessand Ecm to fender harness MAF plug is on it. ( you can make one but its just easier to swap. ) You will need MAF & air box and tubes .as the move sensor from front intake to box ( But I guess you can make wire extension and use in stock location if using a ram air kit ) Your 96 OBD II ECM runs 3 O2 sensors where the 95 doesn't just 1 . NON OBD II Its just as easy to scan with a paper clip . Other than the harness change , this is a straight forward swap .Just move harness and ecm and swap . I did it on 89 with different F.O. and had to swap injector order but no problem.good luck

 

go to www.fordfuelinjection.com to understand obd-I and obd-II differences. 96+ is a totally different animal. so what lostin is saying find a 93-95 bronco/f150 running a mass air 302/e4od combo. grab the entire harness, maf etc and run that. you can even run the 302 mass air ecu but should get a chip burned to make it run 100%. the 302 mass air ecu will run the 5.8 just not to its potential. thats why finding the 5.8/e4od mass air ecu would be prefered.

 

how much does this improve gas mileage?

 

i would not expect more then 1-2mpg at most in primo conditions

 

I took motor and trans out of my old rust bucket which had just been tuned up and had got solid 13 1/2 Mpg for 2 months straight. I put in a truck that actually has a body (not missing a bed and fenders to rust) and and 8 ft bed instead of short. Same gears . All I did was put Maf injector harness on old motor and installed wholesale. In the heavier truck I get 15 - 16 MPG everyday and have got 17 + on interstate. So the 1-2 miles per gal is right. The other 2 I did they put bigger tires at same time so I don't know. But I drive 580 miles a week and the extra can really be noticed. This isn't a set you back in seat swap. But truck hauls better and is alot more responsive

If you can find all parts resonable do it other wise it won't cost effective ( i think) if you don't plan some future engine mods. Good luck
