MAF voltage reading issue
Finally the car starts perfectly BUT we still have an issue with MAF signal on '00 NB 1.8L
Referring to wiring diagram, the central wire (light green/black in our case) should be the signal one.
The boomslang cuts the signal, it goes into EMB IN and goes out from EMB OUT to the OEM ECU
Setting 3-A-0 => very rich
Setting 3-A-C => rich
If we go on EMB datalogging, the signal is ALWAYS 5V. It sounds very very strange. We tried with 2 MAF, and the outcome is the same.
We are not using it for tuning, as we are using MAP sensor.
I've read about the 1k Ohm resistor to be added between GND and signal, but I cannot find any write-up regarding the problem type. Is it the same we have?
Thanks in advance... as usual!
