I have two different MAF's and need the curves for them. Flow vs. output voltage. I can not find anything on them. They may both be the same ... thanks.

what do you need the MAF transfer functions for? Is this for your personal tuning purposes.
What did those MAFs come out of...i might be able to give you a hand....

With Ford meters,
it is easier to start from the known application/vehicle...
Then, if you are lucky, that ecu will have been mapped out, and the binary will be available.
I have NEVER seen a list of MAF Transfers for Ford meters based on part numbers.....
Might be nice to compile one for us tuner guys though....
What vehicles did those meters come out of?

I have a spec racer ford with a Rousch engine that uses either of these MAF's (I think they are the same) and I am putting a turbo on it. I need the curves to do a tune.
The MAF's are from a 5.0 early Mustang I think. They are also on a Ford Ranger (93?) and the Ford Escort about 95.
Thanks

Can you elaborate on the setup a little?
What ecu?
What size injectors?
The car has been running for a while?
If the ecu you have is matched to the MAF you have (assuming these are all properly mactched FORD parts),
then you should be able to do a read of the stock binary to get your maf transfer?
What tuner are you using?
jason
I have all of the bin data but it has already been tweaked by Rousch for the NA version of the engine so I do not know what the un-tweaked curve is. That is what I am after ... stock MAF curve and I can work the tune from that point. I do not want to use an FMU ... I want to do it with the ECM.
The MAF Transfer is what it is.
When you add boost, you may want to make minor changes to the current MAF Transfer, but what you have is likely the best starting point you will find.
I may be able to offer more detailed advice if you address some of the questions I've already posed.
(not trying to be a dick here... but to do a decent job of helping you get where you want to be, we need to know where you are starting from....)
good luck,
jason

Hum ... this sure seems very difficult.
I don't know where I am starting from, as I have said, because the table has already been tweaked by Rousch. I can read the bin but the data is not stock. That is why I want to get a stock table to start from then I have a known. I am not needing assistance with the tune yet but I will after I get a base line to work from and I will really appreciate some help on that. This is my first turbo project.
I put up some info here:
http://www.specracer.rexlantz.com
So ... do you by chance have the stock data for the MAF or know where I might get it? I believe this one was on a 5.0 but I am not sure. I think it was also on the Ranger 2.3 and 3.0.

Really, it isn't difficult
What I am getting at is that 'Rousch' already tuned the MAF Transfer.
If you are using the same meter that came from 'Rousch', then that part of the tune is basically done. You may find that the flow characteristics of the meter are a little different when you add boost, but it shouldn't be by much, if at all (I wouldn't know for sure, as I have not tuned boost yet).
This is assuming you currently have the same meter that was used in the original setup, for which the tune was created.
The part numbers you gave above are not for a stock 5.0 HO Mustang.
There should be a couple more numbers on the top of the meter. Can you provide those? Maybe an AFH70 kinda marking?
In order to find the MAF Transfer for a stock Ford meter, you MUST know the vehicle application. Year and model my work, but all the info I have seen will be listed on ecu catch code.
I don't know the catch codes for the Rangers, do you?
jason
I think I understand what you're saying now. The problem is this is a sealed engine and no one on the planet has the information. I am the only one I know of who has cracked the ECU and has a bin file from it.
The engine is a Mexican 1.9L motor that was not marketed in the USA and there are no more of them. The motor could not pass emissions so Ford kept it out of the country. It has a hemi head and some other goodies. Unfortunately, Rousch chose this motor for the SRF and also picked a bunch of odd parts to make the whole system. I have replaced that engine with a 2.0L stock Ford SPI engine.
The new 2.0 engine does not run correctly with this ECU and MAF. However, I have made some adjustments in the ECU and the engine runs "pretty good" It is still lean in WOT under 70% + load. Without an accurate MAF transfer I really am just chasing it.
This won't be just a one time project. There are a lot of these cars and a lot of these engines. But, I really need a starting point that is a known and that I can duplicate. I can not for example take this MAF and put it on another engine and expect it to work properly (that is what I tried and it does not) without the same tune in the computer. But that tune is based on this engine which is no longer available.
So tell me about the transfer. If I want to lean the engine what needs to be done to the transfer function? That is all I really have to work with.
The MAF numbers are from a early Mustang and they were used on the Escort and on the Ranger. About 1993-5 on the Ranger. 1998-2000 on the Escort for certain.
Thanks,
Rex

Rex,
You are in deep on this project... very cool!
At this point I have to take a step back and ask some more questions....
Why use the ecu you have, when you know the tune doesn't apply to your setup, and the parameters are just now being hacked out?
There are plenty of computers to choose from....
I would look for a well decoded ecu from a motor with the same number of cylinders.
What binary editor are you using?
It may be helpful if you can share this file with others...
If you have changed engine displacement and added boost, then more things will need to be changed than just the MAF Transfer.
Maybe you could make it run with just this fuction exposed, but it will crude at best...
This is why it is best to start with a well hacked ecu... as all of the parameters will already have been exposed for you... AND there will be others who have had experience tuning that ecu.

There are other parameters that should be dealt with before the MAF Transfer...
Engine Displacement Scalar
Injector Slopes
Load Scaling (especially with the addition of boost...)
(and I am sure there are more that I'm forgetting at the moment...)
If you have all of these parameters exposed/hacked, then you're in good shape...
If not, it may be easier to convert to another ecu....
The Ford Thunderbird had a 2.3 turbo for a couple of years, and several of those ecu's are well documented.
The Ford Taurus SHO had a v6 ecu which is also well documented.
I don't mean to discourage you from taking the time to hack out the binary for the ecu you have.
But I have tried to go that route myself, and I found it easier to deal with converting an LA3 ecu to MAF & n/a. (I'm in the middle of this project right now
)Just more options to consider,
jason
LOL … So ... like I said ... this sure is difficult. I only asked for a MAF table. I think I can conclude that it isn't available so ... I will try get this one flowed at the University Aero Lab.There are other parameters that should be dealt with before the MAF Transfer...

I have all of the ECU stuff already, slopes, scalars, load tables, fuel maps, spark tables, etc.
But they all rely on the MAF transfer function to calculate the correct PW for the injector. So, if the air mass flow is unknown then there is no start point and it is impossible to calculate the require fuel accurately. You can just chase it around until it works but the odds are you will never get it right. The MAF transfer is quite important.
I have these MAF's to work with which may be the same:
F67F-12B579-EA
F37F-12B579-FA
I have these ECU's available:
A4D1 .... 95 Escort 1.9L/manual
SV0 ... custom from Rousch via Ford 1.9L EFI (Sealed for SRF) This is using the F37W-12B579-FA
J2W1 ... 93 1.9L Escort/manual
J4A1 .... 95 Escort/automatic
So, Rex...
It seems that you are looking for MAF Transfer files based on the MAS part number and Housing size.
This info does not exist, as far as I am aware...
The way we find our Ford MAF Transfers right now is by looking up the stock binary for the vehicle that MAF was used on.
It would be nice to have that info, but I don't think it has been compiled this way before...

I agree.
Do you have the transfer table from a 94 Ranger then? That is what the MAF fits. Or a 97 -2000 Escort, taurus or any other 2.3L Ranger. I think some early Mustanges used it also.
1. We need to know the ecu catch code of the 94 Ranger.
2. Then, IF that ecu has been mapped out, then we can pull the MAF Transfer from that binary file.
If you don't have the ecu catch code, and that ecu hasn't been mapped, then you have a paper weight of a MAF...
This is why I keep suggesting the use of a known MAF meter....
You have 3 ways of getting the MAF Transfer
1. Find a stock binary for the 94 Ranger.
2. Put the meter on a flow bench
3. Create the curve from scratch using feedback from a wideband O2
Sorry I can't be more help, but that is all the help I can be.
My offer still stands, just let me know if you change your mind.
