The Quick and Dirty (Features and Benefits):

  • More Power:
  • o Stage 1: Max gains of 87 WHP / 109 lb-ft of torque over stock with 93 octane on ‘S’ models. Consult the performance charts for additional octanes and/or detailed data on other vehicle variants.
  • o Dinan +: Max gains of 70 WHP / 89 lb-ft of torque over stock with 91 octane on ‘S’ models. Consult the performance charts for additional data on other vehicle variants.
  • Warranty:
  • o Dinan Stage 1 performance software includes a limited lifetime warranty against defects in the software and provides free updates and reflashes as they become available. Labor or shipping charges are not included in the warranty.
  • o Dinan + performance software matches the factory new car warranty (4year / 50,000 mi) and is the warranty protection commonly associated with the Dinan brand.
  • Stage 1 affords access to numerous octane calibrations depending on your needs (91, 93, 100 and 104). Switching between mappings would require a reflash at a Dinan authorized dealer. Dinan + is limited to a single map (91).
  • Full map rescaling for drivability from idle to wide-open throttle and everywhere in between.
  • Optimized boost control, cam phasing, fueling, airflow and temperature controls for maximum power output that is also safe and reliable.
  • Top speed governor removed.
  • Aggressive sport mode cooling added for optimum track effectiveness.
  • Downshift Auto-Blip added for DSC off / Sport Mode conditions.
  • Upgradeable from DINANTRONICS Elite via trade-in program. Consult B46/B48 FAQ on the product page for details.
  • Retains all MINI factory engine safeguards and adds additional safety protections such as the stationary rev limiter being set to 4000 RPM and implementation of per gear torque limits.
  • Sport gauges rescaled to reflect higher than stock power output.
  • Stock JCW pops and bangs settings retained (JCW), or implemented (S), depending on application.

The Story:

The 3rd Generation MINI carries on the tradition of its predecessors and offers its owners an enjoyable driving experience via the virtue of being compact and nimble. However, stock levels of power are pedestrian for those enamored with maximum performance. This is especially true when compared to its BMW siblings that Dinan has tweaked and improved for decades. With the B46/B48 powerplant shared between both marques it begs the question – what would the MINI platform be like with an extra 50HP or even 75HP to go along with its already gratifying handling characteristics?

Extraordinary is the answer the Dinan R&D team has discovered. The B46 on 93 octane and absolutely no other modifications but the Dinan stage 1 tune clocks in with raucous gains of 87 WHP and 109 TRQ. Even if you wish to retain the 4yr/50k warranty, the Dinan+ variant registers gains of 70 WHP and 89 TRQ. Both options result in nearly ½ another MINI’s worth of power packed into that diminutive frame. What does this mean for you? Fun. Lots of it. Agility and power, together at last.

While increases in power at this scale typically come at a cost to the engine's durability, this is typically due to improper calibrations that are simply after one goal regardless of engine health - maximum power. Dinan’s calibrations are safe and reliable without sacrificing long-term reliability or performance. Dinan performance engine software is so much more than just turning up the turbo boost after all. It is a fully re-tuned engine management program that maximizes power while keeping all the MINI factory safeguards in place. In most cases Dinan software engineers also implement their own additional safety precautions in order to guarantee flawless performance that may not have been needed with factory power levels/programming. Protecting your MINI, while giving the most performance, is the definition of "Performance Without Sacrifice". To do just that, drivetrain and engine components are analyzed for strength, and then the calibration is tested on the dyno and in the real world for durability and drivability. This process has been a cornerstone of Dinan software development for decades and a major reason why Dinan performance tunes are often labelled as being the smoothest, factory-like solution in the marketplace.
