Hi,
I'ts been 2 weeks since I'm studing how to convert my car with HHO.
The only thing that's left is how to control the MAF/MAP and O2 sensors of the car.
I'm planning to use an Arduino microcontroller to simulate the correct output voltage to trick the ECU.
I've been looking on internet and search the MAF/MAP sensors. I've seen how they work.
I don't know what is the logic in the background ... how are they controlled....
Until now all I know is that when HHO is produced then the O2 sensor must be tricked so that ECU doesn't inject more fuel into engine.
Then also I have to take care of MAF and MAP.
I don't know exactly the how the procedure is done... when MAF is increased then increase also MAP.?
I've searched the internet and found only explenation of what MAF and MAP are but no explanation about how to play with them. When to increase or when to decrease the voltage of sensors(between 0 and 5V). For the MAP 5V without engine running, just contact ON on keys.
Also the Lamda sensor ? must it also be tricked?
Since it is a diesel ... what is the ratio for the engine?
