This tune is specifically intended for M60B40 engines running without a MAF sensor*, instead utilizing only IAT + TPS to tune. This tune works with the STOCK Bosch Motronic 404 and 484 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 (O2) sensor will help the ECU reach ideal fuel settings.
*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!
