MINI USA will shortly be announcing immediate availability of the JCW engine tuning kit for the automatic R56 Cooper S. This is the same kit that was mistakenly released for a couple weeks late last year without US certification (however those cars did not receive the correct ECU update that unleashed most of the power of the kit) After lengthy testing MINI USA has received full certification from the EPA and sales can now officially begin. Here’s an excerpt from the internal MINI USA document announcing the release:

>Aftersales is thrilled to announce that the highly anticipated John Cooper Works Tuning Kit for the MINI Cooper S (R56) is now available for vehicles with manual and automatic transmission.

>The Tuning Kit for the MINI Cooper S with automatic and the manual gearbox is exactly the same. The only difference is specific ECU software for each gearbox variant. The ordering procedure remains unchanged. Please refer to bulletin 11 01 07 for details on the ordering procedure, the kit components, warranty and sales benefits.

It’s worth noting that MINI USA has only released the kit for cars built prior to 07.08. An updated kit with a modified exhaust mount will be released for newer cars later in 2008.

Here’s the official part number and pricing information:

John Cooper Works Tuning Kit:
