Any one with an m42 thought of changing the Air Flow Meter Is there a mod to change it to a m44 Air Flow Meter or something else less restrictive ? |
Been there done that. Quote:

i tryed changing m42 air flow meter with a m44 to but the connection are not the same how much did the conversion kit by split cost |
Price .... I think they retail for like $895.00, I got mine for like $800 or so. It includes the MAF and then the ARC II which is a piggyback controler. FYI: If you don't want to spend the cash The connectors are not the same, but it uses the same wires. There is basically one wire for a low load, one for a high load, and then a intake air temp wire. The MAF has then all except the air temp wire. So you will need to run an external sensor for that one. If you want to use a BMW MAF you will just need to get the sensor and then the pin out along with a connector and make your own harness. It will take some effort but can be done. -Chad |
What exactly does the piggyback controller do? |
Arc Ii It allows you to modify the MAF voltage that the ECU sees by +/- 20%. So you can basically make the car think that it is seeing more or less air then it acutally is and the ECU will add or remove fuel. It basically allows yo9u to munipulate how lean or rich the car runs. Now that is just a summary, it is a little more complicated then that. -Chad |
I looked at the split second website, but all I didn't see anything that I thought would work for the 38ti. Which one did you get? |
$800 beans is a little expensive for a mod like this , i got my moss turbo kit for 1500 Cant you use something like APEXi S-AFC II and a MAF from like a GM ? |
I was thinking of trying to hook up a m44 mass air sensor to my m42. The plugs I assume are different, but even if you splice a m44 connecter to fit, does the m44 sensor use the same values as the m42 meter? Even if it can be made to fit, will the m42 ecu be able to use the values? That's pretty much all thats keeping me from trying it. Anyone with that info would be a big help. |

I don't recall if it showed the kit on the website. It is basically the same as the MAF kit for the S14 Or E30 ///M3. I used a 3.0" MAF -Chad |

I hear ya ... Quote:
The MAF is also calibrated to your cars ECU that way when you start messing with the knobs on the ARC II you don't have a signal calibration issues. I.E. The BMW ECU is designed to see 0-5 volts from an AFM, well if your MAF send a 7 volt signal guess what happens, ECU you take a ****, throws a check engine light and makes the run hella lean. So there is a little more to it then that. I feel ya though it is kind of over priced. It is more then just a MAF Kit though it trully is a piggyback ECU, with it you can use larger injectors and even dial out the fuel that you don't need in certain areas and add fuel where you do. -Chad |
Actually ZeroG, I think you answered my biggest question in your last post. The main thing I was concerned with were the values. You mentioned 0-5V. So if both the air flow meter and mass air sensor run as simply 0-5V sensors, they should be compatible and should be able to be run without a piggyback controller. Unless you want to tweak it I guess. Not used to working on MAF's...too used to Chrylsers without them lol. |
so on a mustang 5.0L at WOT the maf's is reading 7 volt signal whould you happen to know what the reading is at idle i might just buy a mustang maf's AFC II and use temp-sensor i have laying around what if i bought a euro 3.5 MAF's would the VOLTS reading be that same as m44 MAF's |
