If you are in the market for a performance chip, consider the W.A.R. Chip, as it will be the LAST performance chip you will ever buy! Traditional aftermarket chips can only run your car ONE way and you are limited with a generic performance tune that forces you to use the octane the chip is rated for. The W.A.R. Chip defies tradition.
W.A.R. stands for “Write and Remap” and is a revolutionary performance chip for European cars up to and including 1995. It is the most powerful performance chip money can buy rendering traditional aftermarket chips obsolete. The W.A.R. Chip is not your average chip because it has multiple functions. It can have up to four reprogrammable & user controllable tunes loaded onto the device. It has a mini-USB port on the side so you can load different performance files from your laptop to your W.A.R. Chip. The Miller W.A.R. Chip even comes with software for your Windows based laptop that lets you modify your tune(s) whenever you want!

You can easily retune your vehicle with our easy to use windows based software.

Remote Tuning Option

If you do not feel comfortable tuning your custom application on your own nor can you find someone you feel comfortable to do it for you, our remote tuning option may be what you need. This will allow us to create a custom base map for you to start followed by tune revisions until both of us are satisfied. For remote tuning you will need to provide us with data like Air Fuel Ratio and RPM from a data aquisition system or a dyno printout. The beauty of the WAR Chip is if planned out right, we can be revising your tune all in the same day while you are at the dyno to speed up the fine tuning process dramatically.
W.A.R. Room
The W.A.R. Room is an online database that you can find all sorts of tunes for your car. When someone finishes a tune, they can upload it to the W.A.R. Room for others to use! It is the ultimate library of tuned and useable files! There is no charge for access to the W.A.R. Room. If you have a WAR Chip, you can use the files that are found within the W.A.R. Room. Organized by ECU type, the W.A.R. Room is easy to navigate and find files that may be beneficial to your car. The W.A.R. Room is continuously growing. Slowly, it will become a great resource that the BMW performance community is proud of.

Requires Windows XP and current Java
