The extra performance achieved by the Powerchip allows your vehicle to respond much better than stock 525i E39 2.5s. You will notice an effortless push back into the drivers seat, to give you a much more enjoyable and at times safer driving experience. The Powerchip will tap into your BMWs hidden reserves, to give you an immediately noticeable improvement from your vehicle we guarantee it!

Torque

Torque is a measurement of your engines pulling power, and its torque that pulls you up hills, allowing your engine a more linear and aggressive acceleration curve. With the Powerchip, you notice the increase in torque right throughout the rev range, which gives you far greater flexibility at low engine revolutions. Towing will become less demanding, and you will no longer feel the need to take the engine to the redline in each gear to get the performance you demand. Its always there for you, when you really need it most!

Torque (lb.ft) Standard

Acceleration
Increased Power and Torque results in faster acceleration. And it is not just standing start acceleration that is improved, your in-gear acceleration is improved and faster. If overtaking is important to you, you will feel safe knowing that you spend less time on the wrong side of the road, improving the safety of your car, for you and your family or passengers. Perhaps you feel that you need that extra bit of power when you are lined up at the "traffic light grand prix" against another car with similar (or more) power? If you want to have the unfair advantage that will give you more GO away from the lights, you need a Powerchip performance software upgrade for your 525i E39 2.5.

Fitting Details

Your car contains the latest technology ECU that can be reprogrammed through the on-board diagnostic port (OBD-II). Specialised software interfaces with your vehicles engine management system to extract the electronic code via serial download. Once the information has been read, Powerchip technicians apply the performance changes and upload the performance program back through the OBD-II port. Installation cannot be performed by the end user. Programming must occur at an Authorized Powerchip Office or at authorised Powerchip Platinum dealers. The programming takes approximately 2 hour's to complete.

On Road Development

Where Powerchip really shines out over its competitors is the emphasis and time spent refining the program for drivability and enjoyment. Much more a real world gain than full throttle horse power runs on a dyno, part throttle refinement is a gain everyone uses every time they drive the vehicle. Flat spots and poor off the line performance are smoothed out in this process, and transient throttle conditions are made razor sharp for the ultimate in response. Real time changes to tables like throttle response and power enrichment are done on road to fine tune the driving experience of the vehicle, with acceleration timing equipment used to ensure consistent and measurable gains in part throttle drivability.

Driveability

Powerchip technicians do not spend their whole research and development focus tuning the full throttle performance of each vehicle. A significant emphasis is placed on the part throttle performance. We understand that driving in everyday conditions is more than just flat out acceleration, with your foot flat to the floor. With Powerchip performance software, your car will perform to its potential, even when you are not demanding the peak performance. You no longer need to mash the throttle to take off briskly, and ingear overtaking can be performed without needing to change down gears. One of the main benefits of choosing to enhance your vehicle with the Powerchip is the improvement you will feel in all driving situations, no matter what your driving style is.

Manufacturers Tolerances

BMW unfortunately leaves large tolerances in the performance characteristics of its entire fleet to allow for drivers that are negligent on maintenance, and who are non-enthusiasts. The 525i E39 2.5 is de-tuned to be able to run on the poorest grade of fuel that the car is likely to encounter anywhere in the world, and also to allow for the small percentage of owners who put their cars reliability to the test due to their lack of mechanical understanding. In most cases, our clients are enthusiasts who place more emphasis on the performance characteristics of their vehicle, and therefore the Powerchip does not need to be programmed as conservatively as the stock software.

Modified Spark Advance

In the old days the ignition distributor controlled the engine spark timing. Changes to the position in the distributor will result in changed ignition settings, and is a good method of tune-up for older vehicles. Modern engine ignition is controlled by a series of tables or maps. These maps give the engine any instructions required to operate, under ALL load and rev per minute access points. Similar to the old systems, advancing the point of ignition within a cylinder results in increased horsepower and toque. It is important not to advance the timing beyond the capabilities of the fuel used, or else detonation can occur. Peak horsepower is achieved when ignition timing is set as close to the point of detonation as possible, without exceeding it. This is the primary purpose for asking the octane rating each client uses most frequently, so that the software is set to the correct level of ignition advance for the fuel used. The end result of ignition advance changes is increased horsepower and torque, resulting in better acceleration and various other driving benefits.

49 State Emissions Legal

The Powerchip complies with U.S. EPA Memorandum 1A, or it has not been found nor is believed to be unlawful for use under the provisions of the Clean Air Act. Currently, Powerchip is not legal in California for vehicles that may be used on a highway. Powerchip is currently undergoing testing for certification under the Californian Air Resources Board (CARB) exemption process.

Our Satisfaction Guarantee
Every Powerchip sold in North America comes with an unconditional 14-day money back guarantee. This ensures that the Powerchip will live up to your expectations, not ours! If for any reason you are unsatisfied with the Powerchip, you may return the Powerchip to your place of purchase for a full refund of the purchase price (not including shipping and handling, installation and removal etc.). Our satisfaction guarantee offers you total peace of mind, and makes the purchase of the Powerchip risk free. By purchasing a Powerchip you have nothing to lose and everything to gain!

Octane ratings

The Powerchip is designed to get the best from your engine, and to do this you must use a high performance fuel (91 Octane minimum). It is not possible to improve the performance on late model fuel injected vehicles using poor quality fuels, such as 87 or 89 octane. When ordering your Powerchip upgrade, your Power Consultant will ask you for the octane rating you would like your program to run. Powerchip Gold 91 is designed to run on fuel with an octane rating of either 91 or 92. Powerchip Gold 93 is designed to run on fuel with an octane rating of 93 or higher. We highly recommend that you use the highest-octane fuel available to you, such as 92, 93 or 94 octane if a higher than 91-octane fuel is available.

Warranty

All Gold 93 Powerchips come with a three year, unlimited mile warranty, which means that if anything occurs with the Powerchip in that time, we will replace it without charge to you. An optional extended Powerchip warranty is also available at an additional $90 at the time of ordering. This extends the warranty period on any Power chip to six years. The terms and conditions of the Powerchip warranties can be viewed in detail on our web site at
http://www.powerchipgroup.com/products/warranty.asp
To briefly summarize the information: if your car is covered by a new or dealer warranty, the dealer may not void a warranty simply because you have fitted an aftermarket product. SEMA, the automotive aftermarket industry body in North America has made the following statements regarding aftermarket products such as performance chips. "The vehicle manufacturer is not allowed to void the vehicle warranty just because aftermarket equipment is installed on the vehicle." ".In cases where such a failed aftermarket part is responsible for a warranty claim, the (vehicle) manufacturer must arrange a settlement with the part manufacturer, but the new vehicle warrant is not void under the law." "If the failure to honor a claim involves the new-vehicle warranty, and it appears that the (vehicle) manufacturer is improperly denying a claim, the incident should be reported to the Federal Trade Commission (FTC)." The fitment of the Powerchip will not have a detrimental effect on your vehicle performance or engine longevity, and therefore does not interfere with the manufacturers warranty in any way.

Value for a Lifetime

The investment you make in the Powerchip will last for as long as you keep your car, and for most of our customers, that is normally for 3 or 4 years. So when you consider the benefits of the chip over a number of years, it is not a lot to pay for extra performance you will probably use nearly every day. As a percentage of the total cost of your car, the Powerchip works out to be very cost effective.

Cost Effectiveness

As we all know, modifying late model vehicles is not a cheap exercise, however, when you look at it on a hp per dollar basis, the Powerchip comes in ahead of any other modification you could make to your BMW. Have a look at just how well the Powerchip stacks up:

Customer Testimonials
Customer Name: Alex B, Short Hills Car: X5 E53 4.6is Testimonial added: Jan Customer Comments:
"I have noticed smoother idling when cold, a much more effortless swing to red line, smoother shifting and an overall improved feeling of torque and acceleration. Install was a breeze. Nearly a night and day difference that I would highly recommend."
Customer Name: James H, Car: 530i E60 3.0 Testimonial added: Oct Customer Comments:
"First of all, X5 rocks after Powerchip. I added a few Dinan bolt-ons and this is a real BMW, not a truck anymore. Wasn't a real truck to start with (4.6), but you know what I mean. By mistake when Dinan stuff was added also Dinan software was installed, and it was actually reasonable, not as good as Powerchip though, but certainly more competitive than M5 Dinan versus M5 Powerchip. For M5 which I also had both Dinan first and Powerchip later hands down to Powerchip, nothing even to compare to Dinan. However, there was a problem with loading software on X5. The key for serial kit would work only once. So I downloaded the original software with a key sent. When Powerchip file was sent to me I couldn't load it because key wasn't recognized by the X5 ECU. Powerchip sent me a new key and it worked. But, there is more. After this I had Dinan mods and Dinan software mistakenly loaded. When I tried to reinstall Powerchip the key was again not recognized by ECU, so Powerchip sent me another key, and it worked. So they sent me 3 keys to fix my X5. You can look at this 2 ways: something is wrong with X5, or my X5 and Powerchip keys, or how Powerchip guys were really professional and send me all these keys to finally get right software in my X5. I aplaud them for not making me sent my ECU to California. Jessie is one smart young guy. Looking forward to Powechiping any car I get a hold of."
