SKU: CHP-M50B25-AN Categories: , Tags: , , , , ,


This tune is specifically intended for M50B25 engines running without a MAF sensor*, instead utilizing only IAT + TPS to tune. This tune works with the STOCK Bosch Motronic 075, 402, 403, 413, and 506 ECUs.

These tunes are region specific, and a tune for sea-level may not operate as ideally at high elevation. The use of a well working, stock EGO sensor will help the ECU adjust for elevation changes.

*IAT sensor should be retained for best results, but may be removed. If you choose to remove the IAT sensor, your tune will be region and temperature specific, as air density is directly related to those factors.

Forced induction is now supported on Over-The-Net (OTN) tunes. However, we do prefer to tune these in-person, and can do so in Florida, California, Colorado, Missouri, Illinois, Nebraska, or Kansas. Please contact us to setup an appointment!

Bring your M50 to life with this fully tuned, daily driven, and track tested performance chip. The SSSquid Tuning performance chip is the most complete tune on the market, with every aspect of the mapping being optimized from idle to wide-open-throttle.

Launch Control: This feature is available only with the M3 075, 413, or 506 ECU (not an M50 413). Please CONTACT US if you have any questions configuring this option.
