I recently did a MAF conv. on my 93 Lightning but this time I did not want to spent 1,500 buying a MAF converssion kit and Baumanator controler like I did for another Gen I Lightnig 393 stroker I sold about 2 years ago:cr:
This time I did a lot of reserch and come up with something on mind so I will try to shortly explain because I'm not too good traying to explain things.:scared1:
If you have a MAF mustang harness some connectors items of this harness can be used as a donors like MAF, Injectors, and O2's connectors if not you can buy them used or new, I had and old speed density harness on my storage so I took the Fuel injectors connectors only.
Items used :
1- 60 pin connectors from ebay $ 199
2- BIO0 MAF/E4OD ECU from ebay$ 200 (California emissions specs)
3- MAF Pigtail $ 22.95
4- O2' extenders $ 30 (did not have any O2's connector so I bought a new O2's extenders for Long tube headers and cut the male connectors and just use the female connectors and wires to be connected with the 60 pin harness extender & to 12V source)
5- 2 O2's "used"
6- Fuel Inj. connectors "used"
7- Wires, wires cover, Zip ties,but connectors & misc. around $50
8- MAF & housing "used"
9- Install 2 O2's bungs at Muffler shop $ 20.0
Around $650 spent on all copmponents not counting the used items I already got.
Below are pictures of items used, the great advantage you can built this kit for around $ 650.00 if you find a ECU MAF-E4od used at e-bay or may be buy one reman at Autozone but it will be more expensive @ Autozone but it needs to be a MAF ECU California emission 94-95 Bronco or F150 with 5.8L and e4od transmission. I think they cost around $260 to $280 with core or more if core is not given but not sure.
I used the diagram of Haynes book but I found only 3 wires to control the E4OD are wrong on this book they are ok but only for E4od on speed density ECU not for MAF ECU so the first time I tried transmission did not shift, I found the mistake because I check on FORDFUELINJECTION.COM where it shows the right pins, did the change on harness extender and transmission worked fine. That is why I choose to buy the 60 MAF Harness extender instead of alter stock harness if something goes wrong and no time to troubleshooting you can always remove this Harness extender and reconect to stock ECU and drive Pick up again and later find problem and reinstall MAF kit.
Now I have the MAF:tu on my pick up and a tweecer and ready for future mods like cams, heads, blower and every thing that MAF offer for tune.:scared1: if you want pick up go back to Speed density just remove harness and install stock ECU and reconnect un-touched stock harness. I left the stock harness along with the just one stock O2 sensor intact in the Pick Up just overlap the new MAF harness in case Speed Density going back, but why?:headscratch:
I had to power the 02's from key on 12 volts and for MAF & Fuel injectors from the 12 V wire feeding the stock Fuel injectors becuase is the same source of suply to 12 to ECU and is recomended the ECU and Fuel Injectors be attached to the same source of supply.:tu so if you want to spent less money and not afraid to work on ECU wiring and have some mechanical incline skills and want to have the advantages of MAF can do for you this is right for you
Is to soon to tell if I will gain slightly MPG right now but what I noticed is a better throttle response , but stiil working on tuning with tweecer, just installed a 24 lbs fuel Injectors and C&L MAF 75mm housing with Mustang 5.0 MAF
On one of the pics. you can choose with MAF ECU you can use , I used the BIO0 Bronco - F150 ECU MAF with E4od california emission but others option are available if you need to choose one check the parts numbers that ends with the letters AAA, AA, HB, JB, ect not the computer catch code:HOGO, BIO0, etc. At autozone they go for the CARDONE part # using the part# not the ECU catch code. there is a list of ECU I found you can used but double check before buy one , I bought the BIO0 Code part # F5TF-12A650-BYA and worked fine.
Due to I can only download 5 pics I'm limited to post more pictures.
