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.

Easy install
Style: Ink
Reliable, vibrant, and easy to install. The print quality is crisp and professional, which is important for my presentations, workshops, and business materials. No smudging, no issues — just dependable performance. Definitely worth keeping on hand.

Hate the Price, but love the ink.
Style: Ink
I totally hate the price of printer ink, mostly when it dries out when not in constant use, but I purchased generic and my printer would not let me use it and i have avoided the firmware update. So back to buying epson ink. It worked the minute i loaded it into the printer. Epson ink is great. it was great color and quality. Just hate the price tag.

Pricey but they work
Style: Ink
Pricey but the remanufactured ones either don't work at all, or they work for a short time then go belly up...
