Performance tunes are available for BMWs up to 2007 MY.

“A recent upgrade carried out on a BMW 530D 2004 E60, showed an increase of 30bhp. The maximum torque increased by 35lb/ft to 405lb/ft. However, the largest gain was a staggering increase of 54lb/ft @ 3200rpm.”
Mike Collen, Managing Director, Diagnos.co.uk Ltd

Like all Autologic® software, the Power Upgrade is available for downloading from the website, and users simply run it on their existing Autologic for BMW platform. The benefits are evident: more power, more engine flexibility and increased fuel efficiency; an attractive combination. Petrol upgrades show more torque, smoother throttle response and speed limiter removal.

Performance tuning
Diagnos has developed tunes for all of the control units listed above. There are however hundreds of variations for each control unit and vehicle. It is necessary therefore, for you to diagnose the vehicle with Autologic and determine whether or not –

• A performance tune exists for the current level of ECU software
• Diagnos are required to develop a Performance Tune for this variation

If a tune does not exist, we can send specific data about the control unit to diagnos. New Performance Tunes can be written and uploaded to the dianos.co.uk website usually within 24 hours.
