Epic Motorsports software increases power and torque output, smooths power delivery, and improves part-throttle drivability. This version of Epic software is designed for race cars running with headers, cat-delete or sport cats, and the secondary air pump and evaporation systems removed. Race cars built for racing use require specialized software to operate properly and this software tune has been professionally developed by the Epic and BimmerWorld racing teams. Note that software for the SpecE46 racing class can be found by clicking here.

ECU tuning modifies the data in the engine computer (ECU). Ignition timing tables, fuel injection, camshaft timing and VANOS, and other data is changed to make more power reliably and without affecting the durability of the engine. This is dyno-developed and race-proven power gains engineered in-house on the Epic and BimmerWorld dynos. In addition to the engine tuning, the rev limit is raised to 7,000 RPM and the top speed limiter is raised/eliminated. Race software is available as either 91 or 93 minimum octane ratings. Additional timing advance on 93 will result in slightly more power but will have less knock resistance in extreme temperatures. The 91 setting may be best for hot climates where too much timing in extreme temps may result in engine knock.

Installation:
Bench Flash (no additional charge): send your ECU to Epic for a direct flash. No hardware required but the car will be inoperable for a minimum of 3 business days.
ECI flash cable (+$99): a cable is sent that works with software on a Windows PC laptop. You read your stock file and email it to Epic and a tuned file is returned. You keep the cable for future flashing. It also works as a diagnostic tool through your laptop. There is no downtime while the tuned file is being processed.

Because Epic software is custom and made using only your original file (not a pre-configured file sitting on a shelf) this product applies to all 2001-2006 E46 325i/330i, including both MS43 and MS45 computers. Your tuned file will be correct for either ECU as it's based on your original file.

Epic Updates/Revisions: Epic includes 1 revised flash at no charge with your order. If you decide the file needs a change, such as the throttle is too sensitive or you want a new rev limit, Epic will reflash the ECU with a revised tune at no charge. If the new file has an advertised price higher than your original purchase you will only be responsible for the price difference.
