MP3 ECU DIAGRAM**NEW INFO**

[mp3boy1984]

once people are done instaling there s-afc can someone pleae do a how-to.

 

[mopiko]

I am planning to wiring it up today, so I'll do my best to write down a how-to here in a new thread. Will keep you all posted.

 

[saided18]

so a S-AFC can fix the problem of running lean at part throttle while under boost and running rich at full throttle under boost?

Hey everyone i was wondering if anyone knew what pin was the injector ground. i have an emanage that im trying to sell because i have had it for so long and can not to this day figure out what the injector ground wire. there are i believe three main grounds for the ecu and i believe one of those is also the injector ground i just need to figure out which one. i want to hook up the emanage and see if it works well with our cars so if anyone and i mean ANYONE CAN PLEASE HELP ME!!!!! i am doing this install to advise others if it will work on our cars but if i cant get any help than i will sell it to the highest bidder.

I dont know if it will help but I can send you the control system chapter from the 2002 manual. Just let me know if you think it will I should be able to e-mail it it is 1.3M.

 

[mopiko]

Does anyone know the location of the Speed wire at the ECU too? Cuz not only I'm wiring the S-AFC but I'm also installing my RSM (Rev/Speed Meter) from APEXi. Thanks

 

[mp3rican007]

yeah i need something to look off of, because traveler gave me all the information he had and he didnt know which wire to use for the injector, so if you could email it to me it would be great.
email to mp3rican007@aol.com thanks man

Well, it is nice to see people actually trying to hook-up the AFC and actually see if it works. There have been a few modes of thought as to if the S-AFC will work or not.

The last I heard it might not because the voltage range the MAF works on is too high for the S-AFC to use and so it might not be able to even read the signal.

It will be interesting to see if you can actually get this thing up and working.

 

[mp3rican007]

according to the information that twizyours sent me the speed wire pin on the ecu would be number 58 that is the pin for vehicle speed. That is according to this information i have.

 

[mopiko]

Thanks mp3rican007 I'll try that. StuttersC, can you get a confirm on your information, I did a sensor voltage check and that wire is reading more thn 5V, I can't be sure since I don't have te wiring diagram to confirm if that is indeed the right wire to hook. If so I would agree it will not work. I got the other parts working properly but not the air flow wire which is the most important in the S-AFC setup.

That is the problem...The voltage from the MAF starts at five and goes up to ten as where I believe the S-AFC wants to see zero to five volts.

The manual/directions for the install should say what the S-AFC wants...And you already know what the MAF signal is sending.

1st mp3 in nh hey i sent you a pm but i forgot some info the knock sensor has to pinouts for + and - ; the + pinout is number 57 and the - pinout is number 59. Hope that helps what did you need it for anyway?

Well, Running a turbo, knock is the major thing to watch.
Now are cars already have an internal knock sensor. Logicly I assume that If I can find the KNock sensor pins I can hook up a AC volt meter across them and I will be able to always monitor for knock, once I learn the sensor ranges of coarse. THe only part that is of some confusion for me is that I know when the car cars open loop, the one where it stop checking sensors, does it stop reading the Knock sensor or does the knock sensor get turned off.

I am hoping I will be able to see any instance of knock this way.

THanks again!

 

[mp3boy1984]

after reading on apexi's website, i belive that there are two types of sensors one that goes zero to 5 and then one that goes 5 to zero, so maybe our cars go 5 to zero. If you hook it all up it will tell you everything that you need to know. Also they mentioned a third type of sensor but i am not sure if we have that one. It's called like a karmann sensor. Once you hook it all up though it should be able to tell you.

Added a few new pins and re added the diagram. Gonna work on some more info to put in here. Working on injector ground and knock sensor.

I think I have the knock sensor figured out for about $100.

I found al DMM sold at partsexpress.com

http://www.partsexpress.com/pe/show...&St3=-91372017&DS_ID=3&Product_ID=10739&DID=7

Its small and has AC and DC voltage also it has data hold so hopefully it will retain the highest value to detect knock severity. Unfortunityl it is the cheapest one that can read as low as .5 volts and has data hold. the others start at 3 volts unless thats just a range.

I am planning on making a quick plug in an holder in the glove box so it can go in and out of the car quickly. Also I am going to run the ECU leads through a relay so I can switch between knock and battery voltage.

 

[twizyours]

Just wondering how everyone is coming along on this. Want to keep it going.

 

[mopiko]

No go on the S-AFC, I can only hook it up as a monitor but if I have the air-flow signal go through the S-AFC it'll stall the car. But other than that the RSM-GP and the S-AFC works fine now.

i was think why don't you make the knock sensor sensor a light that is mounted in your dash. like a led or a litte blub that lights up when knock has occured? just like a shift light. how does that sound?

 

[twizyours]

Did anyone get the e-manage hooked up yet.
