Go with ecu saver. Great service, communication and product.
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.

2011 Mercedes GLK350 back on the road.
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.Brent (Michigan)

Customer Service A+
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
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!

Excellent customer service
Excellent customer service, great quality products, and fantastic turnaround! Very reasonable pricing. Eric and his staff are amazing. Don't be fooled by other services or companies. I only trust ECU Saver! The Electronic Steering Lock failed in my 2012 C250 Sport, rendering the car inoperable. Local dealer wanted $4k to replace the ESL. ECU Saver to the rescue! For $215, replaced the ESL with a high quality emulator from ECU Saver (not the cheap ones you see on other sites) and the necessary programming to match it to the car. Once I installed the emulator from ECU Saver, my C250 started right up without any issues! Thank you Eric and Team ECU Saver! You are the absolute best!

Great product and service.
My existing ECU was not working correctly with poor engine performance. I ordered an ECU clone with EWS delete for my BMW E46 and received it two days later. My car has never run better.Very happy with the product and service.

You guys are the greatest! you certainly surprised me with how quick you execute these services you offer. I was truly blown away by how easy and simple you made it to get my ECU to you and especially, how quickly you did the service and returned it to me.
