More tuning options, its defiantly a pricey system but they have plug and play for s54.
I know our ecus are different but i would imagine that the harness would be same or require minimal changes to suit or cars.
Vi-PEC V88 plug & play E46 M3 MS54 standalone ECU available through Apex Speed Tech

Apex Speed Tech has announced a plug and play S54 ECU kit utilizing the Vi-PEC V88 is available for $3400. This includes a complete plug and play harness. The ECU has dual map capability which means pump and race tunes at the flip of a switch. It also supports the E46 traction control. Apex Speed Tech is claiming they have used this ECU successfully in everything from road racing to 1200 whp twin turbo setups. We haven't seen these twin turbo setups personally or any details of to support that claim but this plug and play ECU should open up the S54 to some interesting custom setups as well as a variety of swaps.
