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 | | | 05-30-2005, 12:05 AM | #5 | Senior Member Join Date: Dec 2004 Location: Muncie, Indiana Posts: 1,551 | What exactly does the piggyback controller do? | | | 05-30-2005, 06:30 AM | #6 | I miss my Ti....... :( Join Date: Nov 2003 Location: Los Angeles, CA Posts: 828 | 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 | | | 05-30-2005, 04:59 PM | #7 | Senior Member Join Date: Dec 2004 Location: Muncie, Indiana Posts: 1,551 | 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? | | | 05-30-2005, 05:28 PM | #8 | Member Join Date: Mar 2005 Location: Brooklyn, NY Posts: 37 | $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 ? | | | 05-30-2005, 07:05 PM | #9 | Senior Member Join Date: Jun 2003 Location: Tucson, AZ Posts: 290 | 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. __________________ Vince Carknard 1995 318ti Active Hellrot, 16" 5 spoke, "Fogged" airbox mod, Stromung exhaust, Bilstein Sports, BMW sport springs, 3.73lsd, others... | | | 05-30-2005, 07:32 PM | #10 | I miss my Ti....... :( Join Date: Nov 2003 Location: Los Angeles, CA Posts: 828 | Bimmer Boi Quote: Originally Posted by bimmerboi318 I was thinking of trying to hook up a m44 mass air sensor to my m42.

If you have your own MAF you can use the ARC II and it is like $400. SAFC works on the same principal as the split second kit you still need the MAF though. Also the ARC II does some signal conditioning as well. 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 | | | 05-31-2005, 04:36 AM | #12 | Member Join Date: Mar 2005 Location: Brooklyn, NY Posts: 37 | Quote: Originally Posted by ZeroG The Split Second Kit incluses a MAF from a Ford.

Your saying that you paid $400 for a MAF sensor that cost ~50 bucks on Ebay ? those guys at Split Second really ripped you off | | | 05-31-2005, 04:58 AM | #13 | I miss my Ti....... :( Join Date: Nov 2003 Location: Los Angeles, CA Posts: 828 | I hear ya ...

Anyway that MAF that came with the Kit is made b y Ford and is the OEM part from a 5.0 Mustang. My Maf is also 3.5" diameter. Now to find a Bimmer one that big you have to go to Europe. 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 | | | 06-01-2005, 03:03 AM | #14 | Senior Member Join Date: Jun 2003 Location: Tucson, AZ Posts: 290 | 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. __________________ Vince Carknard 1995 318ti Active Hellrot, 16" 5 spoke, "Fogged" airbox mod, Stromung exhaust, Bilstein Sports, BMW sport springs, 3.73lsd, others... | | | 08-19-2005, 12:27 AM | #15 | Senior Member Join Date: Jan 2004 Location: MD/VA/DC Posts: 834 | 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 | | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Thread Tools | | Display Modes | Linear Mode | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
