The engine performs Homogeneous injection mode only
NOXEM series NOx emulator is built using the highest quality components
- Bosch’s latest-generation sensor is controlled and measured by ourselves developed analog control module which provides the highest accuracy of exhaust Lambda value. Now you can use NOx emulator Lambda data as reference
- Up to 30V overvoltage and wrong supply polarity protection guarantees the highest resistance to car’s onboard voltage spikes
- High precision reference frequency oscillator and industrial temperature grade components provide uninterruptible operation in a wide temperature range
- High power oversized sensor control stage reduce heating and facilitate the operation of the electronics module at high temperatures
- Double sealed construction with 5mm stainless steel base plate is a guaranty for long and safe operation in hard environment conditions
Electrical characteristics
- Power supply: +9.0 .. +16.0V DC
- Long-term over-voltage (1 hour): +24.0V DC
- Short-term over-voltage (1 second): +30.0V DC
- Wrong polarity short-term over-voltage (1 second): -30.0V DC
- Maximal current consumption (+14.0V DC; +25oC): 2.5A
- Average current consumption (+14.0V DC; +25oC): 0.8A
- Operation temperature: -40oC .. +105oC
Disclaimer
While using NOXEM 129 or NOXEM 130 NOx sensor emulator, the NOx level, emitted by the engine in some modes can differ from value, specified by the manufacturer. The user of the product assumes full responsibility for compliance with emission standards, valid in the country of use.
Attention!
NOXEM restores the normal performance of the NOx system, which is one of the main conditions for correct engine performance. Affirmation for the successful performance of NOXEM – no new error messages regarding NOx sensor in the memory of MSD80/MSD81. However, NOXEM does not guarantee the excellent performance of the engine, if the engine has others, not related to NOx system, defects and/or the required coding procedures, as described here and here, after installing NOXEM are not performed correctly/not performed at all. If you have doubts, that your choice to buy NOXEM, is correct, please, get in touch with Bimmerprofs via e-mail and include an exact description of your problem: screenshots of the INPA error message list, live data, etc.
Bimmerprofs offers help with online diagnostics for customers. More information here.
Attention!
Do not use aerosol type spray (brake cleaner, WD40 and similar) during replacement of the sensor! The fume of these sprays can damage the sensor! Remove the protective cap from the sensor directly before installation. If a spray is previously used, dry the surface using compressed air for several minutes.
