Epic Motorsports Software - E46 M3 and MZ3/4 (S54 Engine/MSS54 ECU)

Full description pending - contact a salesman to receive further information once released

The graph to the right shows three dyno runs, conducted within a 15 minute period on the same day, with zero change in parts or other conditions:

• Blue - Stock software with dyno speed limiter removed
• Green - Common performance software - we were surprised by the indicated results as well
• Red - Epic Motorsports Software, showing an increase of over 10 Hp at the wheels

Street and Race tunes are considered off the shelf items and will be correct for your combination of parts, Alpha-N software must be verified on the dyno due to variances in engines.  Purchase price includes one revision of software as needed.  Additional custom tailoring of any tune is available to squeeze out all the small pieces of performance, please inquire for cost of custom tuning.

Requires sending your ECU to BimmerWorld for reprogramming.
