Miller Performance is always looking for unique ways to help enthusiasts get the most out of their BMW in a safe and reliable manner. Miller Performance is now offering complete tuning packages for your M20 325/525 or M30 535. We have stroker and turbo tuning packages designed to get more power to your rear wheels. These Tuning Packages are designed to give you the best basic building blocks for you performance project. Lets take a look at what these packages offer!
M20 Stroker Tuning Package
The M20 Stroker Tuning Package is designed for those with a stroked M20 from 2.7L to 3.1L applications. Get rid of your ancient, inefficient air flow meter and your generic "one size fits all" tune. The M20 Stroker Tuning Package, gives you the equipment you need to increase your power in the most efficient and reliable manner. The M20 Stroker Tuning Package comes with a 3.0" High flow mass air flow sensor. The mass air flow sensor increases performance by flowing more air, which will yield better low end and mid range power than your stock AFM can provide. It also dramatically improves throttle response!
The most important part of the M20 Stroker Tuning Package is the W.A.R. Chip. The package comes with a Miller W.A.R. Chip preloaded with base software for your stroker application. If you need to massage out the tune in certain areas to specifically suit your car, you are now able to do so! In the past, you could never change the tune on the chip if you were having issues. Now, the W.A.R. Chip allows you to tailor fit your tune if needed!
Here is a dyno graph of an M20 Stroker using our M20 Stroker Tuning Package to get rid of his factory Air Flow Meter and make the power he was always aiming for! As you can see, there was much more power to be had from his generic, Air Flow Meter based tune.
M20 Turbo Tuning Package
The M20 Turbo Tuning Package is great for your turbo powered M20 engine. While many "tune" their M20 turbo with an FMU and it does work, “how well” is the question? Think of an octagon, you can use that as a wheel, sure. But a smooth circle will be much smoother and efficient. Tuning your turbocharged M20 properly will deliver smoother and more efficient power. The M20 Turbo Tuning Package comes with a 3.5" high flow mass air flow sensor. The 3.5" mass air flow sensor is good for up to 320 RWHP. The mass air flow sensor will provide you with a more accurate reading of your air flow than the stock air flow meter could ever, giving you more power, better drivability and more importantly, better reliability. Throttle response is also dramatically improved.
The M20 Turbo Tuning Package comes with a set of 6, 30# High Efficiency BOSCH 4 spray injectors to provide the fuel your turbo charged engine needs. These injectors utilize the 4 spray pattern which improves fuel atomization improving the burn which gives more efficient power.
Again, the most critical part of the M20 Turbo Tuning Package is the Miller W.A.R. Chip. The W.A.R. Chip comes preloaded with our proven M20 Turbo base tune. This tune has been developed in house on our Mustang 1100SE chassis dyno. It has been developed with expansion in mind, meaning you can run more power or a slightly different set up without worry. Our tunes for the factory ECU are unbeatable in terms of quality power delivery, reliability, and drivability. No one else can offer a tune like this for the factory ECU.
Here is a dyno graph of our M20 Turbo Kit utilizing the M20 Turbo Tuning Package (which is inlcuded). There are three pages showing stock, turbocharged, and back to back comparisson.
M30 Turbo Tuning Package
The M30 Turbo Tuning Package is a perfect solution for your turbo powered M30 engine. This package gets you away from using a rising rate fuel pressure regulator as a source of tuning. Back to the octagonal wheel analogy, it works, but "works" is a relative term. The M30 Turbo Tuning Package is designed to get your turbo project up and running better than you could ever imagine. The package comes with a 3.5" OR 4" (power dependent) high flow mass air flow sensor. The mass air flow sensor is key for extreme accuracy of incoming air for you engine. Knowing the volume of air entering your engine is far more accurate compared to pressure. Volume is what dictates power. The 3.5" MAF can support up to 330 RWHP, while the 4" MAF can support 500+ RWHP.
The M30 Turbo Tuning Package comes with a set of 6, 36# high efficiency, 4 spray, BOSCH injectors to fuel your turbo powered engine. As usual, we use the best quality products, and the 4 spray pattern improves fuel atomization thus improving the burn and providing more efficient power.
Like the two tuning packages mentioned above, the M30 Turbo Tuning Package comes with a preloaded W.A.R. Chip. The M30 Turbo tune that has been perfected over the years will provide you with factory, or better, drivability. This tune is a great starting point for any project, and will allow you to make safe, useable and reliable power. Our factory ECU tunes have been proven time and time again; don't let your M30 turbo engine hide power from you. Take advantage of our Tuning package to meet your engines full potential.
