MAF Late model 460
[font size="1" color="#FF0000"]LAST EDITED ON 05-May-01 AT 12:29 PM (EST)[/font][p]Hey guys heres an update.
I returned the ordered wiring harness because i found one in CA that had the fuse box etc on it, much cheaper and easier to do that than fiddle around with with a bunch of loose wires that i had to put a loom around. The # is the same as above, F7TZA581 (15.00) it is on the truck now and running off my old computer but i still do not have the SEFI injector harness which will be 62.08, then i will go after the O2 sensors. we should have all the parts then. hopefully. Ill post the computer # and injector harness # around next week some time then ill let you all know what bugs i run into installing them. Hey mike let me know latter this year if this MAF thing works, how well that Vortec installs. Im thinking maybe next year or so putting on one too. after the rebuild of course.

Oh boy guys did i bite it,
$400 dollars all the parts ordered mis shipped, not matching all wrong missing plug ins that are on the diagrams and the system is turning into a nightmare, ive done some conversions but this one takes the taco, i may stay away from ford wiring harnesses for a long time after this is done.
The CA computer does lean out fuel mixture or at least detune the motors firing as emissions increase a guy up here who heard about what i was doing went out of his way to get in touch with me and tell me about his experience putting the CA system on his 94 ford 460 harnesses not matching having to make his own harnesses and diagrams not coinciding from ford. along with the computer not runnig the motor at full potential. Ill keep you all posted as more develops, the green monster is apart im taking photos but everything so far has been wrong from ford or just been a plain head ache. I knew what i had gotten into so the loss of the money is ok I just hoped that i could make it work.
This same guy pointed out a company that does these converts and he said that four of his buddies have used the interactive MAF system on thier 460's and it all plugged in easily cost around a 1000 dollars but was worth it. I may go after that once i save a few more $$$$, that all it takes to make a truck run like you want it to. Here is a phone # of the company that makes a complete harness and computer set it is 770-720-1259 they came highly recommended by the ford tech line and vortec for dealing with ford MAF and the 460's.
I have another business trip to go on and without the green monster its going to be a long one. oh well, we'll see what happens, ive got plenty of time to fix my mistakes and several contingency plans to make this thing work.

Alright guys,
Several people have written me an email or two asking that i keep this updated so here it goes. I ordered the Interactive kit reasonibly priced, when compared to other options for a 460. Uses performance parts etc. Ill let you all know in two or so weeks when it gets here. If you are interested in feedback or photos post to this message string and i will try and give you what info i have or dont post, also thier are several other members who are looking at this closely, Mike and Xaviar namely. Mike is trying to form a bulk order or at least get a discount for the FTE members so this too might be something to post here about keep your ears open and well see how this all pans out. It appears to be the most complete setup with good tech service. the number is posted one message up.
By the way i got lucky and way able to return my flop with trying to use fords stuff, stay away from that the factory setups detune the motor o2 sensors in front and rearof cat. This Interactive kit is an overlay harness, computer and all the trimmings necessary to complete the conversion.
Ill keep you posted

Gentlemen, I started another post titled something like "460 MAF we have a winner" So anyone interested on a group buy of some sort or an FTE Club discount post something on there or add to this post or email me at meshaffer at mindspring.com within the next week or so. I am going to try and save us a few dollars but I need your support to do that... Look out Lightnings the big blocks are comming!
Have a great day!

Hey guys,
I don't want you all to think i forgot about this, Interactive has been a little slow on delivery of the MAF convert kit but as soon as its here i will email everybody i can and ill post here. Thanks for the support and the interest it makes this all more exciting.

Hey Guys guess what it showed up today, cool huh. The kits is essentially the 302 conversion but hey you learn something every day, they added thier digital injector meter for adjusting voltage and a new airmeter and 80 mm mass air meter. The computer code is A3M1 and the kit does not have any added plug ins for two O2 sensors. fairly simple and strait forward. It is pre set to 24lb injectors. Hang on to your hats and ill keep you all posted its going in over the next couple of days.

MAF Late model 460
OK Guys,
Here we are one week after finalization of the project, Here’s a simplified yet informative description of what i went through to get it to work. I do i have one problem that one of you might be able to help with, The Ford Motorsport SD EFI to MAF SFI conversion uses the A3M1 computer but what year and code would you use for a code scanner to trace problems?
Oh well, The kit comes with a voltage regulator, overlay harness, mass air meter off a 80 mm 24 lb/hr Lincoln, a new computer with the above listed number A3M1, new BAP sensor, air box and Y fitting. I recommend buying a new O2 senor before this begins so you have it. First we began by disconnecting the existing main harness that enters the computer on the drivers side fire wall. We then removed the computer, and replace it with the new one provided. With that in place the truck was ready to have the Overlay harness bolted on. The Overlay goes on before your existing main harness. After bolting the Overlay on we bolted the main harness to that. The injector plugs are numbered and start at the first cylinder on the front left injector bank, we unplugged the factory injector wire and plugged in the overlay wire. This is very strait forward, it starts on the front left as i said loops around the rear of the intake throttle body and back to the front right bank. Once the injectors were plugged in to the new harness we went on to the mass air meter. Now since the Mass air meter is off of a Lincoln, it uses the latter oval six pin design which is easily adapted to the overlay harness through the digital voltage meter which uses the six pin on one side and the older four pin on the other. The Y pipe supplied is helpful but I would advise those interested in this conversion to invest in the factory ford 460 MAF intake hose assembly from a CA truck, its much cleaner. Now with these two items plugged in the last thing to do was for us to locate the MAP sensor and replace it with a BAP sensor, They look identical and they use the same plug in and mounting bracket. This is located by your AC/ heater core just by the hood line and over towards the motor. We then flipped the Voltage regulator to Direct, which uses the computers guest-i-mate to fire up the truck. It ran rough for about 5 minutes, as soon as the motor reached operating temp we flipped the regulator to adjust and began leaning out the mix. The motor smoothed out and ultimately or at least at this time with my headers and headwork etc, the voltage for injector duration is .90-.92 and on a 8.0: stock motor we found that .82-.80 was also close to even. I am no expert but the motor ran well for a week with no problems no codes everything smoothed out mileage increased about 1.4 mpg on a highway trip.
Now that’s not saying that i haven’t had any, a friend of mine jumped in to drive it, pushed the accelerator while cranking the truck flooded it severely, burned the O2 sensor along with something else (maybe EGR or EGR position sensor or a leaking injector?) and since then my truck floods a little at start up is hard to start and throws a check engine code. Still scoots but the rich running and hard start and periodic flooding is bugging me any ideas? Just to re-iterate this is not related to the conversion, it is related to a carbureted motor driver trying to run an EFI motor. could be costly.
Any questions? and i do have photos on file and can take more specify and ill try and be of any help.
Take care fellow Big Block fans

Dusty,
Great dude.... Your MAF conversion project is moving forward, I wish mine was... Just to busy at the moment! Why dont you check with Ken and see if you can post your pictures and descriptions on this site somewhere? Perhaps in the how to's... or on my personal FTE web page (dosent exist yet?) I think others (especially me) would be interested.... What do you say Ken? Also Ken did you ever get the chance to speak with the boys at Interactive on a FTE club discount? They wont deal with me I am not important. I have a personal deal and Dusty already bought his but I am sure someone else in the club has a 460 they want to convert....
Have a great day!

[font size="1" color="#FF0000"]LAST EDITED ON 05-Jul-01 AT 05:27 AM (EST)[/font][p]Dusty, good to see everything went well on your install.
Sorry to hear about the starting issues, due to a friends mistake. Have you tried disconnecting the battery for a few minutes and reconnecting and seeing what happens?
I like Shami's suggestion. It would be nice to see those pic's. Ken how about posting them for us? A club discount would be nice if a deal could be obtained from Interactive?
Thx for the info Dusty.

This is a test guys to see if i got this uploading thing down. If so the next several photos will be of the installed kits and the parts provided with the kit hopefully this works

I see that i need to get my cropping down but it worked, cool, heres the next batch of photos
Here is what came in the kit, as you can see it is relatively simple and the necessary hoses would have to have been fabricated if i had not gotten the CA hose assembly. The Voltage regulator is hanging from the mass airmeter, the BAP in the little bag(canter), the computer just to the right of it, and the overlay with eight injector plug ins and the four pinn plug for the MASS Air meter.
https://www.ford-trucks.com/dcforum/User_files/ddestruel/3b538fc8774850e0.jpg
This is the photo of the left bank you can see in the upper corner the old MAP and the BAP (still not completely installed but functioning) also if you look at the injectors, you will see the old plugs and the new black overlay harness.

https://www.ford-trucks.com/dcforum/User_files/ddestruel/3b5390f57e9abe73.jpg
Here is a photo of the Overlay, Wire loom one is for the mass air meter plug, and wire loom two is for the sixteen injector wires. Hopefully you can see that the overlay bolts onto the computer and that the original plug then bolts to that with no problems. Very clean and simple for installation.
https://www.ford-trucks.com/dcforum/User_files/ddestruel/3b53924c086c18d4.jpg
Here is a picture of the right hand side, showing the hose assembly used and the mounting of everything once it was complete, note the voltage regulator mounted on the mass air meter, all this required was a piece of 1/2 by 1/8 inch steel five inches long, drilled to mount to the air filter bolts and bent to clear any other objects then a piece of two sided high temp eletrical tape.
https://www.ford-trucks.com/dcforum/User_files/ddestruel/3b5395db1edd7ffb.jpg
An attempt at a close up of the Voltage Regulator and where it is mounted to the mass air meter, you can also see the two different style plugs that the regulator adapts between.
https://www.ford-trucks.com/dcforum/User_files/ddestruel/3b53942d1359e21d.jpg
Best of luck to anyone who attempts this, it is worth it, the computer scan code for trouble shooting is F w/ 93 as the year. I am pleased with the kit and recommend it to anyone who has modified or is planning to modify thier 460, the power and responsiveness is phenominal.
Thanks Ken for your help please let me know if these are clear enough photos or if i should retake some.

MAF Late model 460
Hey Guys,
A couple of people have inquired about 460 EFI mods, one that i found before i was able to track down the MAF conversion is a Comp Cam Part #34-220-4
@.50 206 206 Lift .467 .467 Lobe Cen 112*
It works with the speed density, puts the system at the brink of it's limits. but several guys in town have used it with success, and i imagine with the mass air, the extra fuel it will probably run even better.
Anyways i said i would post this information so here it is.
