EWS delete service worked great,

Works perfectly!

All around great service recommended to all for there excellent service again A+

great service...no hassles...great turn around with item... install and performance of item is awesome...good communication though out...

Was very quick and knowledgeable. Great turnaround time and pricing.

I had high hopes and great expectations for this company…but after receiving the product it wasn’t as advertised. I was expecting an emulator that resembled the Mercedes esl housing, just in a plastic casing. However, I received a mk3 emulator, which after getting a response from ecu saver as to why, turns out it’s a good thing and a more dependable product. All in all, great service and communication, and my Mercedes is back on road with no esl issues.

I ordered ESL and two key fobs for my c63. Everything works as expected. The seller was also very responsive with all of my questions from start to end. I’m satisfied with the product as well as customer assistance.

exceptional service we work with them as a independent shop and recommend them highly

Quick turnaround
Save me from having to go to the dealer

Dme ews delete worked and was able to just plug and play to the car with no issues

Customer service, the response to any questions I had in a timely manner.

Great service and fast delivery, very professional people I’m so happy because they resolve my problem and great price

Very fast amazing service

Eric provided top-notch customer service and communication. I would highly recommend this company many times over.

I ordered an ESL clone for my 11' Mercedes GLK350, due to my OEM unit failing. The service was incredibly quick with the turnaround being no more than a 24hrs once received on ECU Saver's side. I ran into a couple of questions for ECU Saver and they responded on got me pointed in the right direction right away and all is good. The vehicle is back on the road and saved a lot of money without dealer input.
Thanks again ECU Saver, top notch.

I was looking at other Mercedes EIS Cloning on EBay, my concern was they had only been on EBay since 2025!!
But ECU SAVER had a wonderful history of doing Mercedes EIS IGNITION CLONING ON EBAY SINCE 2015!!!! HIGHLY RECOMMENDED SELLER!!

Found ECU Saver while searching options for ECU cloning.
Sent my burnt ECU to them and they attempted a clone. Once I received it I installed it but it did not run. It was doing more than my prior ECU so I knew something had gone wrong in cloning.
They agreed and offered a reflash.
After reflash all good.
I should have done this first but didn't know the old ECU had actually flashed inside since I did not open it.
ECU Saver had great communication and offered a solution to a problem that otherwise would have been extremely costly.
Thanks ECU Saver!

Everything went as it should. Communication was great and the service extremely fast. I even requested alternate shipping and that was done at no extra cost. Best of all the car is running fine, no codes, and it scans perfectly on my BMW and a generic scanner. I fully recommend ECU Saver for your CPU needs!
