Audi 5cyl
apparently needs Analog input multiplexer with no pullup, and min 6 EGT to have enough analog inputs for DBW (electronic throttle)
- always specify mcp3208/ch 2,5,6,7 as analog inputs with pullup in the first place. If specifying these without pullup, others will NOT get pullup (we refuse to divert from the standard in an unreasonable way). Look at the EC18 paper to see which channels have pullup by default.
- 60-2 HALL sensor
- 5xEGT (6xEGT with CLT sensor)
- Drive by wire throttle body (Bosch part number: 022133062 AG)
- Oil pressure
- Fuel pressure
- K-thermocouple can handle it, with K-thermo amplifier, similar to EGT (possible to configure CLT to use mcp3208 input, also useful for air cooled "Head temp" sensor)
- I found an original oil temp sensor (Porsche part number: 90164163200) It doesn't need another amplifier. The most simple i think.
Vems V3 will order in the following options:

Analog inputs:
- Ch0: (0-5V NO pullup) Multiplexer ChannelA EC18/14
- Ch1: (0-5V NO pullup) Multiplexer ChannelB EC18/16
- Ch2: (0-5V NO pullup) TPS2 EC18/3
- Ch3: (0-5V NO pullup) PPS1 EC18/17
- Ch4: (0-5V NO pullup) PPS2 - EC18/15
- Ch5: (pullup) EC18/2 Switch
- Ch6: (pullup) EC18/6 Switch
- Ch7: (pullup) EC18/12 Switch
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)
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?
