Fix your EWS issues with this ECU. If your car wont start because you got a new key or the EWS module went bad, this is an easy plug and play solution to get your car back on the road. Works on 330, 325, 525, 530, E46 and E39 cars produced from 2000-2003. Also on some X5/3 cars with an m54. 

 

Will not work on MS45 Cars!!! Commonly 2003 and on cars, except xi's. Always double check!!!

 

This is also a solution if the stock ECU malfunctioned and you need a new ECU and do not want to go through the expensive hassle of realigning EWS. 

 

With this DME/ECU you will no longer need a functioning EWS system to start your M54 engine. That means this DME/ECU will be plug and play for any E46/E39/X3/5 with an M54. This is also ideal for swaps into other chassis like an e30 or an e34 for example. It is a good way to work around a faulty EWS system. Also a good solution if you want to install a remote start system in your vehicle. Useful in track cars to save every bit possible and reduce electrical starting issues at the track.


This listing is for the EWS deleted DME only.

Just an unbelievable purchase and strongly recommend
Color: Black, Size: Medium
Unbelievable! One of the BEST purchases I made. Fits perfectly, wasn’t wrinkled at all. In fact, I don’t need to take it to the cleaners to be pressed. Class all the way. Well made, elegant, fabric was perfect as it was not too thin. Compared to tuxedos in the store and this was exactly the same. Only difference is this suit was $150 less!

Good. Decent quality.
Color: Black, Size: Small
The quality is good, especially for the price. I didn’t like that the wrist buttons were non functional. We bought cuffs that he couldn’t use. It looks nice. The size is a little big for my son, but that was kind of expected. I was hoping we would get lucky and that wouldn’t be the case but I couldn’t find any suites in a smaller size that would arrive on time. He is 5’7, 120-125 pounds. It was mostly in the shoulders that it looks big. He is thin. The arm length fit him but he does have long arms. The pants fit with a little looseness. His jeans size at American eagle is 28/36, but he can fit slightly bigger with a belt. The pants were good but the vest and jacket were a little big. They’re just slightly long and jacket is big in the shoulders. We got a size small.

QUALITY AND COMPORTABLE FITTING IN LOWER PRICE...
Color: Navy, Size: Large
WOW! this suit really true to its sizes description... I ordered in a different company before this, but I have to return it TWICE because of wrong size fittings... Finally, this beautifully tailored suit timely arrived before my son's wedding reception, and we are ready to celebrate!!! Thank you and might order some different colors in the future... I wonder if they can make the pants in higher waist and straight cut or wider for the legs in the future as an option... Just a thought since slim fit pants are slowly outdating...

Great quality product!
Color: Black, Size: Large
Great product and great fit. I ordered a Large and normally wear a 42 Regular. Jacket was perfect, as was the vest. Pants waist is flexible and fit fine but length needs to be shortened. Overall, I’m impressed with this product! Highly recommended!
