  From $499.00

  Models

  Choose an option20002001-2003Clear

  Fuel – Selectable fuel octane rating (91, 93)

  Rear O2 Sensor Delete - If you are running aftermarket headers please select O2 Sensor delete. We will remove all coding associated with rear O2 sensors

  SAP (Secondary Air Pump) Delete - If you have deleted your Secondary Air Pump, please select this option and we will remove the coding from the DME/ECU to avoid a CEL

  Cold Start Delete - All E39 M5's have a cold start calibration to heat up the catalytic converters. If you're unhappy with the way your M5 idles/runs while cold, select this option and we will adjust the cold start in your tune. Highly advised if you are running a catless exhaust system

  Speed Limiter Removal: The factory DME limits the vehicle to 155 MPH via internal software. This option removes the limiters to allow exploring the upper end of what these vehicles are capable of.

  SMG Shifting Improvements: One of the most well-reviewed options we offer is the modification to the shifting characteristics of the SMG. Improved shift speed and smoothness at all RPM and load combinations.

  O2 Readiness Override (For off-road use only): One of the largest restrictions in the S85's airflow path is the close-coupled catalytic converters located in the headers. Many aftermarket off-road use headers to remove the primary cats or replace them with high-flow race cats to allow the engine to breathe better. This results in a "Service Engine Soon" light illuminated on the instrument cluster as the DME stores a code for "Catalytic Converter Efficiency" due to the increased oxygen present at the post-cat O2 sensors. This option removes the SES light generated by this condition to allow for other more significant error codes to alert the driver when something is wrong.

  RPM Limiter Raised: Standard option is for 8500 RPM.

  VANOS Adjustment Improvement: The factory calibrations reduce the maximum speed at which the VANOS system is allowed to change timing in certain areas. This is done to reduce edginess in response at midrange load and speeds but results in some hesitation during rapid throttle application.

  Stage 2 Calibration available for cars with long tube headers and running CATless.

  Cold Start Delete: This option removes the catalytic converter heating routine which was implemented on most modern vehicles for the purpose of meeting ULEV and SULEV emissions certifications in the US. The US DOT set the requirements for these certifications so that a new vehicle entering the US market must meet the applicable emissions requirements within a short period of time after the engine start from a cold condition. In order to achieve this, most all auto manufacturers relocated the catalytic converters as close to the engine as possible (in the actual exhaust manifold for most BMWs) and implemented a "Katheizen" (German for Cat Heating) routine in the DME. This Katheizen routine alters the exhaust valve timing, fuel injector pulse-width, and ignition timing to allow for incomplete combustion of a cylinder's air/fuel charge before entering the exhaust manifold where combustion continues, rapidly warming up the catalytic converter. This accounts for the "cold-start" sound of the S85. Selecting this option disables the Katheizen routine entirely and has no negative effect whatsoever on the normal operation of the engine. In fact, it is our opinion that combined with the low cylinder pressures and higher than average oil consumption of the S85, that this routine may be a contributing factor in the short life span of the primary cats many S85 owners have experienced over the years.
