“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.”

“I didn’t get to drive my vehicle because now my air suspension won’t work. I have yet to confirm whether this is an ECU issue. Although this unit was well above the other sites asking price, I’m hoping that its customer service will make up for the difference.”

“I mean yea they tested the CAS Module to my car but the problem is intermittent and usually begins after a day of driving so it wasn’t a surprise when they sent it back saying it was good. Put it back in my car, drove it for a day. Busted again.”

“I sent my ecm to PA by USPS 3 day priority mail, rom FL they rec'd it in 3 days over the weekend. They did not look at my ECM until Tuesday. They stated they got 50 ecm's in the mail on Monday. At that time I stated to replace it. It took ECUPRO until Thursday to ship out my ecm. They state on their website and the invoice it is Fedex 2 day Express. I did not get my ecm until late Tuesday, 6 days later. I took my car for a short ride on Wed. about 10 miles total, it seemed to work fine. The real proof will be tonight when I hve to drive 35 miles for groceries and back home. I am praying it does not stall, like it had been.”

“Reviewing prematurely just to get the warranty extension. Not sure if I’m going to need it yet or not. Received my ECU back and the cylinder #3 misfire was fixed but immediately after installation I have P0001 code for fuel system circuit open that I didn’t have before so I now have to take my car to a mechanic to get the fuel system tested before I can send my ECU back in for warranty repair. I will revise my review depending on the final outcome.”

“Well, except for the length of time it took and the lack of communication, the experience was good. We sent in a customer's ECM for testing and to see if it was repairable. The website states a total turnaround time of 10 days maximum. However, it was more than 3 weeks before it was finally determined that the ECM was not repairable, we requested a new one (reman, programmed from the original one), and received it back (almost a month total). Our customer was NOT pleased that it took so long. When we received the replacement unit, it was layered thickly with dust, looked like it had been sitting unpackaged on a shelf somewhere for a couple of years. We had to clean the unit before we could take it and install it in our customer's truck. However, since it has been installed, it seems to be working properly so far. I had to constantly contact the company to get updates on the progress, and they were not always responsive. This was our first time using this company, and I'm not sure we will use them again unless the situation does not warrant needing the ECM repaired and/or replaced in a timely fashion. I used email AND telephone to communicate with the company. They sometimes responded within 24 hours, sometimes not at all. I wouldn't use this company if you are in a hurry for something.”
