FAQs

Which engine sensors are monitored by the Bosch M7.9.7 ECU on the Saipa X100?

The material lists key monitored sensors including throttle position, intake manifold pressure and temperature, engine speed (crankshaft), camshaft phase detection, upstream/downstream oxygen (lambda) sensors, coolant temperature, and knock sensor detection.

What inputs are considered additional and not monitored by the M7.9.7 ECU?

It specifies additional inputs not monitored by M7.9.7 such as the power steering pressure switch, crash switch, A/C switch, and A/C compressor switch.

What does the M7.9.7 ECU block diagram include?

The block diagram outlines ECU architecture with inputs/outputs, microcontroller elements (including FLASH and EEPROM), and interface paths like K-line for tester and immobiliser, plus various voltage supplies and signal groupings.
