Do you own a 1994-1995 325i BMW? This car is a champion even on these days! Almost a muscle car! And we say almost, but don't worry, the "almost" part will be gone once you install this chip! :-)

This high performance Chip will work on both, manual or automatic transmission models, equipped with VANOS system (Non-Turbo). You may install this chip in the DME (engine computer) of some late 1993, most 1994 and early 1995 models, as long as the DME number is "0 261 200 413", manufactured by Bosch.

A 28-pin EPROM socket and detailed installation instructions are included. About the 28-pin socket, most of the DMEs installed in these cars already have the stock chip installed on a socket. You just pull out the stock chip and insert the new one. We include the socket, because as we found out, there are a few units out there that were built with the chip directly soldered to the circuit (what happened Bosch?). In that case, you will need to unsolder the stock chip and solder the socket in its place, so you may insert the new chip for performance or the stock chip for cruising.

This chip was reprogrammed with higher fuel injection at specific points and a more aggressive ignition timing, specially for producing more torque and more horsepower (you know, Jim Comforti style). The revlimiter (redline) was raised from 6400 RPMs to 7000 RPMs. It will allow for even more power at those high engine speeds momentum, without the risk of spinning too high that could cause a valve float.

If your car is equipped with the EWS security (anti-theft) system, included in the late 1995 models with the same DME or ECU, you can still use this chip, but two simple wiring modifications must be done to deactivate the EWS-II system and enable the starter. For more information, please check the article in the link below:

This chip retails for $300.00+ in other stores, so get it while it lasts. We are sure that you will be satisfied with the results obtained as soon as you install this chip!


(1) Fuel and Ignition Tables were remapped and optimized for producing more horsepower and torque.
(2) Revlimit (Red line) was raised up to 7000 RPMs
(3) Top Speed governor removed to allow the car to reach its natural maximum speed.
(4) Will get rid of EWS with two minors modifications to the wiring.
(5) Will ONLY fit the Bosch 0 261 200 413 DME.
(6) Must use at least US 91 Octane fuel (R+M/2), or Europe RON 95 fuel
(7) Not designed to be used on Turbo or any other boosted application.

FAQ (Frequently Asked Questions)

Q. Is this a real chip or one of those resistirs sold in fancy boxes as "chips"?

A. These are real EPROM chips (memory devices). These hold the program to be run in the DME computer. We modified such program code to accommodate enhancements to fuel delivery, ignition management and some other parts of the engine functions that are controlled by this computer.

Q. Are these chips vehicle or application specific?

A. Yes. They will only work with the models or applications listed here in this page.

Q. How can I identify my computer?

A. To identify your engine computer (DME), you must look at the computer's top cover label. The number should be "0 261 200 413". If the number is different, this chip will unfortunately not work with your DME computer. For help locating your computer in your car, please refer to the above illustration. It is located bellow the passenger side wiper assembly, on the engine bay (under the hood).

Q. I found my computer, but instead of "Bosch", it reads "Siemens". Will this chip fit on my computer?

A. Unfortunately, this chip will not fit in computers manufactured by Siemens. The program structure is for modifying the stock Bosch engine program on this specific DME computers.

Q. How can I differentiate between the DME with, and the DME without EWS security system?

A. You may easily note the difference between the two, just by looking at the color of the sticker on the DME. If the sticker or label is silver colored, it is an EWS ENABLED DME. The DMEs without EWS have a red or brownish colored label on it.
