Description

This performance chip is made specifically for the 731 or 885 head on the M20B27 2.7L 325e block with Motronic 1.1/1.3 upgrade. This is referred to by a number of names, such as: a “frankenstein” engine, M20B25+27, M20B257, “stroker” motor, “2.7i”, or “327i”. Please specify if 731 or 885 head was used, as the combustion chamber designs differ.

This chip is also intended specifically for use with the M30 VAM (AFM). The M30 VAM (Vane Airflow Meter) requires a different sensor calibration than the stock M20 VAM, and therefore requires a specific tune.

Bring your M20 to life with this fully tuned, daily driven, and track tested  performance chip. The SSSQUID performance chip is the most complete tune on the market, with every aspect of the mapping being optimized from idle to wide-open-throttle.

    Idle and on throttle AFRs are spot on. Engine seems to run very well on this tune. Extremely happy with it.
