| ==Audi RS4 MAF Sensor Conversion==
| |
| A cheap alternative for the HPX PMAS MAF is manufactured by Bosch with the part number 0 280 218 067 (or 0 986 280 219) and is installed on the Audi (R)S4 B5's 2.7 V6 biturbo engine and is able to measure upto 1800kg/h.
| |
| | |
| | |
| The MAF sensor module comes preinstalled in a 3.5 inch housing and has a 5 pin connector (Audi part number 1J0973775A) with the following pinout:
| |
| Pin 1 - IAT sensor output (not used)
| |
| Pin 2 - voltage input 12V (red?)
| |
| Pin 3 - common ground (black)
| |
| Pin 4 - voltage input 5V (brown/white)
| |
| Pin 5 - MAF sensor output (yellow)
| |
| The IAT output on pin 1 can be connected to an aftermarket logging device to monitor the intake air temperature before compression, or in case you leave it unconnected, make sure to seal the pin in the plug, to prevent the maf from corroding like this.
| |
| | |
| Pins 2, 3 and 5 should be self explaining, you can just connect them to the OEM MAF wires, or create a new 4-wire loom and run it to the cable distribution box located under the intake manifold.
| |
| | |
| Pin 4 need a solid 5.00 volts supplyvoltage, as this is the reference for the MAF output signal. This is absolutly crucial for the MAF to work properly!
| |
| | |
| The MS43 has two integrated 5V outputs, one for the electronic accelerator pedal and one for the electronic throttlebody, which you will preferly use, because you can tap into the wire right in the distribution box.
| |
| | |
| By the way, this is pin 7 at the middle ECU connector (X60003) for the voltage U_DKG according to the manual (brown/white, 0.5mm²)
| |
| If anybody is concerned about the MAF drawing too much current, during operation it only needs 1,1mA
| |
| | |
| | |
| | |
| Now that you have the connection from the MAF to the ECU, the next part is applying the MAF hack (512k file) and editing the sensor definition (64k file)
| |
| | |
| You have two options to double the MAF limit:
| |
| First is to do it manually with a HEX editor and changing the bytes 0x3D8A3 and 0x3D8C7 from "4E" (1024kg/h) to "3E" (2048kg/h) and double the conversion in the Tuner Pro MAF table to "0.03125*X"
| |
| Second is downloading RomRaider and the MS43 definition .XML file, flick the switch under the "Forced Induction" section and use the special MAF table right next to it.
| |
| Either way you have to recalculate the four checksums in the 512k file, even if you use the CHK5/EWS delete File from Daniel, as this only disables the fifth checksum in the 64k file.
| |
| | |
| In addition to that, you need to (suppress the MAF DTCs with zeroing "C_ABC_INC_MAF" and "C_ABC_INC_MAF_MON",) set "C_MAF_KGH_R_LS_MES_MAX" to 1800kg/h and C_MAF_MAX to 1389kg/h (the highest value possible for this constant).
