Audi 5cyl

apparently needs Analog input multiplexer with no pullup, and min 6 EGT to have enough analog inputs for DBW (electronic throttle)

60-2 HALL sensor

5xEGT (6xEGT with CLT sensor)

Drive by wire throttle body (Bosch part number: 022133062 AG)

Oil pressure

Fuel pressure

Oil temp (What kind of sensor do you recommend for upto 170C? I know it's hot but possible...

Bluetooth

Analog inputs:

Please adjust below to the changed ADC inputs, as above

-ETC bridge controller

-Analog input multiplexer

-5*EGT Amplifier(outside)

Multiplexer inputs in the following way:

ChA1=EGT Amplifier1 (0-5V without pullup)

ChA2=EGT Amp2 (0-5V without pullup)

ChA3=EGT Amp3 (0-5V without pullup)

ChB1=EGT Amp4 (0-5V without pullup)

ChB2=EGT Amp5 (0-5V without pullup)

ChB3=Oil temp (Pulled up)

Ch6=Fuel pressure sensor (0-5V without pullup)

Ch7=Oil pressure sensor (0-5V without pullup)

The other analog inputs:

Ch0:TPS2 (0-5V without pullup) EC18/14

Ch1:PPS1 (0-5V without pullup) EC18/16

Ch2:PPS2 (0-5V without pullup) EC18/3

Ch3: Clutch switch for launch (pulled up) EC18/17

Ch4: Program switch (pulled up) EC18/15

Ch5: ALS switch (pulled up) EC18/2

Ch6: Multiplexer ChannelA EC18/6

Ch7: Multiplexer ChannelB EC18/12

I would like to use the original speed input from Audi dashboard. (white/blue, motronic connector pin50). This is a digital signal from the original dashboard. I have never seen this until working.

What should we do to use this?
