The Epic Motorsports Software calibration for the Spec E46 racing class makes a decent power increase (typically about 10hp over stock, but this is NOT a guaranteed number), provides a proper calibration for the spec race exhaust for this class, ensures reliable and safe operation of your engine, and removes many of the pesky electronic nannies, emissions issues and check-engine lights that are unnecessary on a race car.

This software requires your ECU to be shipped to Epic Motorsports for the flash upload and sealing of the ECU per SE46 rules. The ECU is returned to you with the required seals. Typical turn-around time is one week. If you need your ECU returned by a certain date, please contact us to ensure proper handling and to determine expedited shipping needs.

Instructions for order processing are below, please read!

SpecE46 Software Features:
  • Optimized timing
  • Optimized VANOS timing
  • Optimized DISA engagement
  • Optimized fuel mapping for spec exhaust
  • Revised rev limits: 6500 1st-4th gear; 6800 5th gear
  • Several limp mode functions eliminated
  • Disabled emissions systems
  • Speed limiters removed
  • Raised idle speed prevents stalling for lightweight flywheel
  • Coding for auto-to-manual transmission conversion
  • Read and Write protected (you will NOT be able to flash over this ECU file once sealed)
  • Fully sealed with tamper-proof seals
The sealing process of your ECU is not as simple as a custom flash, and therefore will require up to one business week for processing. Rush processing is available with prior planning - you MUST discuss this with your salesperson at the time of ordering to determine if existing work schedule allows the expedited processing. Once sealed, your ECU will not be able to be overwritten or modified in the future. You can have Epic Motorsports reverse this procedure in the future for a fee, which will require opening the ECU and breaking the Spec E46 Seals. If your Spec E46 seals are broken, you must return your ECU to Epic Motorsports for a full inspection and potential reflash (and additional charge).

Order Processing
Pre-Flash Procedure: You must have a properly running car before tuning your ECU. Please read any existing fault codes and get the problem fixed prior to upgrading. Adding the Epic calibration to your ECU will not solve your pre-existing problem or make Epic Motorsports or BimmerWorld responsible for diagnosing your pre-existing problem. This software is designed to function properly with a racing car built to the SpecE46 rules. Some fault codes are intentionally left alone to aid with diagnostics. Any additional fault codes will indicate an actual problem with the car (not tuning related).

SpecE46 rules require a MS43 ECU from a 2001-2/2003 330i/330ci/330xi. Cars made after 2/2003 use MS45 electronics which must be converted to MS43. Ideally this means the MS43 conversion should be running before you send in your ECU for programming. EWS-delete software is not a standard feature of SE46 software but is available separately to aid in the conversion (see Related Items below). Any starting or running issues after an MS43 conversion will not be software-related and we will not be able to troubleshoot your conversion. For more info on the MS43 conversion, click here.

Processing Instructions:
You will need to remove your ECU and send it directly to Epic Motorsports for them to load the Spec E46 calibration and seal the ECU. Insure your package for $600 and include a printed copy of your BimmerWorld order. Then email your tracking number to [email protected] and include your BimmerWorld order number in the email. Ship the insured ECU package to:
