In addition to increasing boost and optimizing the fuel and ignition data, the DinanTronics Power Module is tuned for the Dinan Intake and Dinan Exhaust on the S55. The Dinan tuner box plugs into the existing sockets on your engine computers 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.

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.

This kit fits cars with a mechanical wastegate, which was replaced with an electronic one around production date 6/2013. If your car was produced in June 2013 you should check which one your car has prior to ordering. 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 M3/M4's equipped with the Competition Package. Compatibility with the Standard Package is available in a different kit.

Feels cheap, not good for old eyes.
The watch seemed to work good. But it felt cheap, and I was looking for something with better illumination and easier to read. I ended up returning it.

Best autograph pens I've found!
Color: Multicolor, Size: 1 Count (Pack of 4), Style: Fine
I love these pens! They come in a nice hard case so no worry when throwing them in a backpack. Perfect for autographs, they dry extremely quick and are very brilliant colors.

Amazing pens/markers
Color: Multicolor, Size: 1 Count (Pack of 4), Style: Fine
Bought these for my son and I- we had the opportunity to meet with several of his favorite professional NHL players. He wanted to have a lot of his card collection signed so I did a little research and saw that this is the pens that the sports card companies use for autographs... I tried them and they are everything they advertise... Beautiful card autos!
