“The replacement part did fix the issues that my son was having. So thank you for that. But the extra key is not quite what we expected. The physical cut key does not work on the doors and the trunk, though the FOB does. And the Fob is not sensed by the car it will only start it while in the steering column.”

“ECU PROS DID A GOOD JOB ON GETTING MY DME REPLACED HOWEVER THEIR WEB SITE SAID 8 -10 DAY TURN AROUND. AFTER 13 DAYS NO CONTACT. I CALLED THEM AND THEYBSAID THIER TEC QUIT AND THE ASSIGNED ORDERS WERE ON HIS DESK. NO CONTACT LETTING ME KNOW. AFTER I CALLED THE SECOND TUME IBGOT A EMAIL FROM ANOTHER SAYING HE HAD TO PROGRAM MY CAS AND GET ME A NEW KEY . NO CHARGE FOR THE EXTRA. AFTER 20 DAYY I GOT THE DME, CAS, AND THE NEW KEY MOF MY 650I. PLUGGED IT IN ALL WORKED. MY ONLY COMPLAINT IS POOR COMMUNICATION. BUT THE WORKMANSHIP IS TOP NOTCH.”

“Good company to deal with. I sent my ECU in for some ghost data I was receiving on my scanner. They claim to have found the wrong file in my ECU which I have a hard time believing. They did provide me with scanner data (supposedly my ECU) reading the correct information on there test vehicle. However upon reinstalling my ECU on my vehicle I still have the incorrect data. I’m a professional mechanic and have ruled out my vehicle for other issues. I still feel my ECU is compromised.”

“EcuPro technician was very professional, all repair and price were explain before completed. I wish EcuPro was able to send me an Emulator so that I can start my 1998 Mercedes Benz C230. I am still searching for an Emulator so that I can get the Benz car going.”

“They did excellent work on the Cas. They would get 5 stars but they had absolutely zero communication with me. I asked questions in my order portal, after I paid in full for a repair before even having the unit sent or tested. I had a question about what to send, no response. I had a question about it being received, no response, after they said the unit was diagnosed, they asked if I wanted it repaired, which I had already paid for. Then they said they seen the payment and would repair, but nothing after that. I asked if they were sending th unit back, no response. They just don't communicate at all with the customer.”

“Sent in my FRM for testing, and came back needing repair, DME for testing and came back needing replacement and the CAS to plug and play testing. I’d recommend if you want to use shop pay that you select the highest service first if you want to try that option in the long run to separate cost if you need payments. I initially selected to pay for testing and wanted to use shop pay for the service and was not able to change it later.. keep that in mind. That is not something ECU pro can do anything about but being knowledgeable in that is beneficial to customer calling in and being given not completely correct information. So now ya know. As far as the FRM it was plug and play and seems good, the DME however is throwing codes and I will need to send it back. They car ran through and cycle corrected old known codes and cleared, however after 30 miles or so I got a engine light for a open circuit thermostat me as well as I couldn’t get the sunroof to engage to open and close. I ran a diagnostic again and it states that the engine or model is not listed under the correct year, I paid to have this done at a shop. The thermostats had been replaced previously. When a diagnostic was ran it threw random codes like airbag sensors not connected, and the seatbelt lights wouldn’t turn off. These were not codes I had before. I have a pending call out to customer service and can update the review once completed. The service is fast, they answer when you call and they communicate however it will be multiple people. The service website system to chat back and forth isn’t the best online, but email works well. I also kept having issues uploading docs when logged into my account in the site. These are basics that could be fixed or looked into or remove the option to do so if the feature doesn’t work. Overall I would recommend and use them again if I have to, just need this final part fixed.”
