escapre tb 4.0 maf write up(pics added)
Alright guys heres the part list and years:(ill add pics when i can get a chance)
(IF YOU DO NOT HAVE A TUNER ID SUGGEST YOU GET ONE BEFORE DOING THIS. GET A XCAL2 FROM fred a.k.a BOSS 3.0
Escape tb-2001/$60 on ebay
composite upper-2004 ranger/FREEBIE(RPS member)
4.0 maf-96 exploder. You want the SOHC. I have the OHV its a little smaller./FREEBIE(RPS member)
On the upper intake you will need to bore out the inlet with the biggest cutter(hole saw in my case) to get a better benifit from it.
BE CAREFULL AND DO NOT BREACH THE IAC HOLE AT THE TOP OF THE UPPER INTAKE.
You will need some shorter bolts for the upper if you had an aluminum one. And you will need to drill out the inserts for the bolts on the composite upper.
You will also have to trim the tb a little to clear the IAC. I had to extend the IAC plug and TPS plug so that they will reach.
I took engine gasket material to make a gasket to match the tb.
On the upper in take you will see to cavities on either side of the iac hole. I filled them in with some jb weld. Then used some RTV to make sure i had no leaks.
THIS IS IMPORTANT TO DO FOR THE IAC HOLES, TO GET THE MAX FLOW BETWEEN THE TWO BECAUSE THEY DONT MATCH.
NOTE: if you have the throttle cable mode done, snip them off. With this setup its just a little bit longer.
I also did a EGR delete. YOu will use most of the lines that come off of the aluminum upper.
Whatever you dont use find a way to close them up(since they are vacuum lines).
You also will have to figure out a way to remount the coil pack since it will no longer bolt the the upper. (Once I get a chance to fix mine I will post pictures and add to this write up.
temporary i need to make it out of one piece and paint it.
THIS IS THE HARDEST PART OF THESE MODIFICATIONS... ITS ALL JUST LITTLE NIT PICKY THINGS THAT YOU HAVE TO DO TO GET IT RIGHT.
If you may have noticed I have cruise control. You will have to fab something up to get the cable attached. I will post pics when I get a chance to do it.
IF you guys have any questions feel free to ask me ,pm me, whatever I am always willing to help.
I think that should cover it. Having an efan will help the install too since the tb angle is a little more towards the radiator then the stock.
If I missed something, just ask me. Hope this helps out anyone that has the GO FAST BUG like I do.

So, is having the bigger MAF necessary? And why is it that you have to get tuned? Is it only for the new MAF? I don't know, I'm just wondering why my MAF wouldn't be sending to the ECU that there is more air going through than normal. I'm not really knowledgeable when it comes to ecu's so any insight would be great.

the larger MAF isn't going to do you any good unless you have a complete exhaust setup (headers, muffler, and piping).....your engine can only get so efficient....the amount of air taken in has to be able to exit....
You would need a retune to get the PCM mated to the MAF....from what I have been told, it is hard to get the tune right for a new MAF...
good job on the write up....

Not so, Maurice. 3.0's have VERY restrictive MAF's compared to 4.0's. It actually will help as it's a huge restriction in the 3.0. That's why the MAF mod does so much for a 3.0 truck, but rather less for a 4.0 truck.
Fred can do the retune easily as I believe he's done this before for folks.
A 4.0's MAF should be as much flow area as a NA 3.0 will ever need.

'05's are nice because you have that already low-restriction MAF.

throttle bodies are different and doesn't require a retune...they are not controlled by the PCM.....

If you get to look at a 4.0 MAF, it's body is so much bigger the flow restriction is much less. In the pic below, the red line shows where the MAF sensor went before the cut was made. Compare that to the 3.0 which goes all the way to the bottom of the narrow tube in both metal and plastic versions.

I have no pics of an unmodded 3.0 plastic MAF, but here's the old metal one and the design and blockage amount are similar -- blockage is about the same. Pics are from Fred's RoguePerformance.com site.

But with the 3.0 it's hard to get there -- but it can be done. In fact, Fred and Wayne posted graphs showing that very thing happening with a MAF I believe in their posting on the new high flow MAF they have for 3.0's.

Escape TB CAN be done without a tune, but there would be lots of learning. Anytime the KAM is killed (pull battery), the learning starts all over.
The datalogs from Brice show a HUGE increase in part throttle air that tapers off as TPS increases and goes to zero just after 3/4 throttle, supporting the fact that it is not the larger bore, but the increased air at smaller throttle angles that is helping.

So, with knowing that you CAN overload a MAF, would you say it's possible if this part throttle air increase tapers off after 3/4 throttle?
