Dinan Product Description

The DinanTronics Power Module is the least invasive way of getting more power from your F10/F30 35i. The Dinan tuner box plugs into the existing sockets on your engine computer(s). The original wiring harness plugs into the Dinan tuner box. There is no cutting or splicing into wires and the whole harness is completely reversible at any time. Dinan has shown a gain of 77hp and 81ft-lbs of torque with this system on the standard 335/435/535.

Because the DinanTronics module plugs directly into the engine computer, it can control the data from every sensor on the engine - not just the two or three that other piggyback-style modules use. Instead of only modifying a boost and RPM sensor, the Dinan power module sends a modified signal for fuel and ignition tables, target Lambda (AFR), exhaust temperature, knock sensors, and more. It has the ability to correct short term fuel trim and ignition timing errors so even as the boost increases through the whole RPM range the engine mapping remains where it should. Not only does it make a lot of peak power, but it's also a smooth and consistent power gain over the entire RPM band. The Dinan tuner module is the most sophisticated on the market and is the only one that is 50-state legal.

Installation is plug and play but requires access to the entire engine compartment. The engine computer(s) is part of the intake manifold so access is tight. The Dinan module is installed under the radiator support and the harness has to be run to each computer. Detailed instructions are included but professional installation is strongly advised if you're not used to working around your engine.

Note: Compatible only on vehicles equipped with the N55 engine (model year 2013+). This kit is currently NOT for cars equipped with BMW M-Performance software (MPPK). For MPPK equipped cars there is a separate part number. This version of the DINANTRONICS Performance Tuner is ONLY compatible with vehicles equipped with an electronic wastegate. Vehicles with a manufacture date prior to 07/2013 should utilize a mechanical wastegate. Vehicles with a production date after 06/2013 should utilize an electronic wastegate. Only a visual identification is 100% accurate. Please consult the wastegate identification guide HERE to accurately identify what is on the vehicle.
