Supercharged 4.0L SOHC

[BonesDT]

what exactly is the 'neutral safety' switch?

im familiar with the 3-way clutch switch. i know one is obviously for the starting system, since i needed to jump those wires to be able to drive, and i know another is to disable the cruise control. i notice the third is connected to the computer somehow, but i dont know the function of it, maybe its this 'neutral safety' switch or i also notice i do not have the automatic door lock feature that the automatics have when you shift out of park.

the only wiring information i have is a 'factory' CD. would you be talking about Helm's wiring books?

as far as getting a computer from a like vehicle, there is not '99 SOHC manual explorer. i would have to use a 01/02 and up, which is part of my concern if there would be issues with this. i have been through more dealerships than tanks of gas and called the ford hotline with a new story each time. even if i decided to wing it with the new computer from a 2002, i am unable to order it or get a part number.

as far as wiring harness, i had to rip out all the sensors and solenoids out of the old auto and wire them up to the old harness just to get the engine to run almost perfectly smoothly. but as far as wiring up my reverse lights and the manual trans OSS, i do not have them wired. again, i am just unable to get part numbers.

just some additional information, i would further like to get a computer that is also intended for a manual t-case. even though i dont have a manual yet, i would rather design my own seperate circuit to control the t-case in order to have 2wd high in place of 'auto' and also in future anticipation of a manual t-case swap.

I've been trying to get the part numbers from the 2002 Ranger FX4 since this seems to be the most similiar set-up.

I have spoken to Brian several times. I'm sure he knows what he is doing and he has asked me to call him to talk further which i have not done. I am just hesitant to 'add' a chip. Im imagining a chip will correct fuel curves and idle speeds. He also mentioned that he would 'turn off' the auto transmission 'switches'. But I am concerned that it is more than just 'turning off' things in the computer because I notice the clutch pedal is connected to the engine controls in some way in which the automatic wasn't. Further my M5OD-R1HD manual trans (the heavy duty version meant for the 2001up SOHC) has an Output Shaft Speed Sensor unlike the older M5OD-R1 (for the OHV) which does not have the sensor. I'm sure this sensor has some sort of input value to the engine that needs to be programmed into the computer. I would feel more confident with a 'stock' set-up where I would have a solid new computer that is perfectly meant for my set-up. But I am still unaware of certain computer/electronic changes in the SOHC from '99 to '02.

sorry for throwing this out in a supercharger thread, but new computers came up and i have been trying for a long time and information on this topic is extremely limited. i wanted to catch you guys while i could in an active thread. thank you.

It is possible for someone to custom fabricate a supercharger onto a V6 SOHC. If you have fabricating skills, welding skills and an endless supply of raw materials. There is a matter of tuning once you do get it to run. I can tell you, we spent six months trying make a design that comfortably mounts the Eaton M90 under the hood of an Explorer. There is a reason why we went for the M62 blower. For one it fits. It has an internal bypass and easily puts out 7lbs of boost.

I respect a guy who is willing to take on such a project. But there is a reason why a junkyard blower costs $200 and a refined supercharger kit cost $3995. Some guys do not know what they are getting into. You can look at what Doug has done as an inspiration. But also consider that Doug is one extremely capable indivisual and apparantly a very good welder. Your results will vary!

Our kit has a cast inlet adaptor and discharge manifold, special EGR tube and air filter box. It also comes with 30 psi injectors, 80mm custom calibrated mass air sensor and a custom Apten Chip. This kit has been in the works for threes years. The idea of a custom kit up and running in a few weeks would be quite an accomplishment.

OKay the wiring diagram book should cover both auto and manual transmissions.

If you compare the two side by side you may pick up the differences.

If Brian does a re-flash of your PCM or installs a chip he would be able to shut off the automatic switches as you said. However if I was you I would want everything to function, and to function right.
Meaning the T case wont shift into Low range unless you are in N.
Also the cruise control should shut off when the clutch is pushed in, this you wont need anymore so it can be bypassed.
The truck should also not start unless you are in N or the clutch is peressed in and of course the reverse lights should come on when you are in R.
All of these wires can be fixed with your new tranny.

Simply turning them off is the easy way to get rid of the CEL.

The changes will take place inside your new tranny harness and a couple minor ones inside the main computer harness under the hood, near the brake booster.

You can probably retain your PCM, and reduce the number of automatic functions you have Apten "turn off" by getting most (if not all) of the circuits to work as they did with your auto....

First thing to do is get the wiring schematics for the truck, and if necessary the schematics for a 5 speed truck similar to yours....(ranger, sport track) but I would be surprised if the diagrams ware not in the same book (on the same CD)

Wow

im also running the large intercooler off the Thunderbird SC, And I will experament with octane levels. Soon after once some more money comes around i will get a chip. But I dont understand why everyone is whineing about how difficult it is. im fabricating a plate from a weld shop to hook up to the Intake, and im using large flexable silicone hoses to get the air around to the Intercooler. Its not all that difficult

HAHAHAH

 

[caldi55]

sapogmxr Whats so funny

 

[GaSouthern1]

The fact that you think this is gonna be a pretty easy thing to do..but good luck...i guess.

 

[caldi55]

Southerner have you ever tried

 

[Nicaraguense]

Hey man

I'm not rediculing you

 

[GaSouthern1]

If it has taken EE this long to get it to work perfectly and they have a team of people working on this thing, and you expect to go pull one off of another car and just toss it on the Explorer and get it to work then I think you are a fool, plain and simple. Sorry if that hurts your feeling, but I would love to see you prove me wrong, I honestly would.

 

[caldi55]

i can understand for the people who have tried this before and it was easier to use a different charger, but for everyone else out there who would never try because they heard it wasnt going to be easy dont be so skeptical. Thats all im saying

i have moved my computer discussion to a new thread:

thank you for helping me on this subject

in defense of caldi55, he has not mentioned the value of boost he is using but he has emphasized he is using "LOW BOOST". as far as I'm concerned, this is significant issue. the lower the boost, the simpler the install. technically you can have forced induction by blowing through a straw in your intake and tweeking the computer to add the slightest bit more gas. take a blower and strap it to your fan belt and tweek the computer a little more, you can run 1-2psi.

caldi55 made no claims on how efficient or how powerful his supercharger will be. i feel it would be very simple to strap a blower on the top of your intake and hook the belt up. it may not be efficient, it may not add even 1hp, it may even just rob your engine of power as another accessory, but you can say you supercharged it and you did it for cheap, in your backyard, and in a week.

Took the words right outa my mouth... Good luck on the project.

 

[caldi55]

Im not making any claims on how well it will work, but i will dyno it before and after and keep you all updated. Its an EXPERAMENT I want to make it work because everyone said it would be to hard, so Lets wait to see the numbers

 

[ton_e_montana]

Come on guys, calm down a bit. No sense in attacking the dude. It might not work but could be an interesting experiment nonetheless.

 

[sapogmxr]

Hey if it works that would be a great accomplishment.

 

[matey]

i want one :australia

 

[caldi55]

I brought the metal piping to work and sanded it all down to get the 3.8L off it and put a 4.0L before I Powder Coat it

 

[GaSouthern1]

Hey, although I dont think it will work well I did make sure and say that I would love to be proven wrong, you have a lot of work ahead of you, I can honestly say good luck but I am skeptical.
