HFM5 into m42b18 motronic 1.7
Hello, I want to install the converter into my 318is.
I bought HFM5 80mm for improve the performance. I have installed yet innovate wideband. Anyone have the oem vaf pinout? |

For help to next, i found that diagram.
I see into lamda menù the MTX-L option. but MTX-L have programmable output, with that option what signal need the converter? |

Hi.
To find pinout of VAF we typically remove it's plastic cover and watch directly on a board. First we see the signal from the flap - you see there a slider and it is not difficult to find on what pin it goes. Next you will see some wires from IAT sensor - one of them is signal - it goes directly on some pin of the VAF's connector. And other wire is connected in parrallel to some pin which is also connected to the ceramic resistive board - this is a GND( ground). And the last available pin will be a 5 V reference voltage. If it possible, please attach a photo of your VAF with removed plastic cover - so we can see a slider and a ceramic board - i'll try to show you on this pic. |

My recoomendation is to try each output function of Innovate and check which will be as close as possible to what you will see in tuning software( Oxygen sensor signal readings is AFR multiplied by 10). Let me know the result , if it will be needed i will add additional corections in software. |

this is the vaf and this is the connector, i wrote the resistence from slider to each pin and the voltage on each pin in other, on my HFM5 have temp sensor, i'll connect that direct to converter? |

As i see your AFM has CO potentiometer too.
So you need to dissasemble AFM and measure CO potentiometer's resistance and setting, next you can place the same value and setting external potentiometer in a wiring. Or you can remove it from AFM and install in wiring . Also i marked IAT's pins - you can desolder and use it as IAT in new installation. If i found the right schematic it seems that pinout should be like this Цитата:
