Dinan Product Description

Stage 1 (DINANTRONICS Performance Tuner ONLY) Maximum Power: 295 HP, 327 lb-ft of torque.

The DinanTronics Power Module is the least invasive way of getting more power from your 228/328/428 SULEV. 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 36hp and 44ft-lbs of torque with this system.

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: This version of the DINANTRONICS Performance Tuner is ONLY compatible with vehicles equipped with the N26 engine. In stock trim, we found that the N20 engine produces more power than the N26 engine at peak rpm (+24 Hp at 6,000 rpm). This, despite BMW’s claims that the N26 engine produces just as much power as the N20. Below 5,500 rpm, both engines perform identically. By all means, the engines are identical, except for the EVAP system and the catalytic converters. The N26 engine uses higher density (read: more restrictive) CATs, which robs power from the engine at high rpm. The N26 CATs have 900/600 cells/sqin, while the N20 CATs have 600/400 cells/sqin. This difference also affects the power gains with DINANTRONICS.

Benefits of the DINANTRONICS Stage 1 Performance Tuner for BMW N26 Engines:

  • +36 HP @ 5500 RPM, +44 lb/ft @ 3500 RPM
  • Won't void or negate your warranty
  • Emissions legal in all 50 states
  • Plug & play installation in two hours or less
  • Quick, easy, and discrete installation
