ECU Remapping

Looking to improve your vehicles torque, increase throttle response or achieve better fuel economy?

DME (Digital Motor Electronics) Repairs

German Auto Engines are built with electronics to help the different components communicate about performance, air to fuel ratio, economy, etc. If one of them isn’t working properly it can cause big problems. We can safely repair, reprogram, or replace these components to have your car driving like new again.

Radio Pixel Repairs

Noticing that the screens in your vehicle are flickering or not working at all? Not having your dashboard delivering you the information you need is a pain. We have the experience to repair or replace your pixel screen. We even carry the screens onsite, so you don’t have to wait around for one to be ordered.

Second Hand Modules

At GMW, we repair and sell 2nd hand ECU modules. These components are refurbished to the highest standards and tailored to your vehicle. They are also a more affordable option than new modules and come with an operational guarantee.

ULF/MULF Telephone Repair (Blue tooth)

Staying hands free in your car is vital to safety (and following the law). If your vehicle’s phone system seems to be failing, we can diagnose and repair the issue. We’ll thoroughly inspect for problems, then come to you with the best course of action to get it back up and running.

ECU chip tuning is changing or modifying your vehicles computer software settings to gain many benefits related to its performance. Basically it is engine tuning where the computer in your engine can be modified to increase your fuel economy, pulling power, gain more torque or produce cleaner emissions.

That is dependent on your specific vehicle and what you plan to use it for. If you are putting a lot of miles on your car, then it may be advantageous to have an eco-tune that will optimise your fuel economy and emissions. If you are looking at racing your car, then you might want to consider a performance chip to give your car improved power and overall performance improvement. If you want to know if a tune is right for your car, contact our knowledgeable team today and we will be happy to discuss whether an ECU chip tune is right for your vehicle.

There are a few tell-tale warning signs that there is an issue with one of your vehicle’s ECU chips. These include:

  • Check Engine light coming on or staying on after resetting
  • Problems with your car starting
  • Your engine turning on or off for no reason
  • Loss of spark
  • Water Damage to your ECU
  • Loss of fuel injection pulse or fuel pump
  • Overheating of ECU

If you notice any of these issues, contact us today to schedule a vehicle diagnostic test to prevent more serious issues from occurring.

As long as you take your vehicle in to a qualified mechanic who has the skills and training, like our team at GMW, then it is 100% safe. The key differences in taking your vehicle into someone who has little experience in ECU tuning, remaps or programming is it can lead to your board diagnostics being misdiagnosed. This would create more serious issues, more costly repairs down the road and you may be at risk of voiding your vehicle warranty.
