Had codes for CPC hardware failure in my 2019 Freightliner Cascadia. Shipped my unit to the ECU pro folks and was notified when they recieved it. They communicated with me that it did need a repair. The time frame was only about 2 days and it was repaired and overnighted back to me the following day. Sent me a video of the cpc repair running in a test truck they have on site also. Super happy with my experience and would definitely use them again and recommend to others who had similar problems like myself.

Very helpful

Good repair and fast shipping equipment.

It’s still not reading

Hello I used ECU Pro for 1 st time, I assume and thought I had ECU issues or maybe Replace, after further Testing my ECU was found to be Functional Working, Nxt exam was my EIS exam & Key Fob , which found my Key Fob needed to be Re-Keyed to be in Sync with EIS, Thks to ECU Pro With accurate Diagnosis of this Situation.

ECU PRO is the best.

I had 2 different places local to meet quote replacing my FRM in my 2011 328i. I was told the original one was fried and could not be used again. One quote was north of 1200 dollars, & the other was over 2000. I send the original to The ECU Pro and they returned it to me quickly. Installed it back in my car and haven’t had a problem sense. I will be a lifelong customer!! They saved me thousands

Wanted to wait a bit before I gave a full review. Cpc repair turnaround was extremely fast( I did choose express repair). Cpc was re installed after repair and truck has been running perfect! No more supdden shut downs or flashing dash lights and the no start issue is gone as well. Truck is a 2018 cascadia and has been running daily since repaired cpc, THANK YOU!

I have a 2001 BMW 740I that would start and sometimes it wouldn’t. I had the original ECU and another one that was put in the car in 2021 by the BMW dealer to fix an Engine Fail Program issue. The problem reappeared this year so I sent both ECUs to ECU Pro. I was pleased with the way they approached the issue of the Ecu units I sent to get tested. They were able to find which one was working, I was emailed a video that showed the test and results. When I received the unit back I installed it back on the car and it has been 300 miles and the car has been running great in fact I noticed the consumption of fuel is better. I would definitely used their services again, not only did I save a lot of money and heartache. The car runs perfectly and the staff at ECU Pro is attentive, on schedule and professional

ECU Pro tested and repaired my FRM quickly and sent it back to me super fast!!! I received the module and installed it on the same day. Started up my car and everything works, the lights, windows, door locks, etc ! Thank you!!!

I had a ton of things go wrong with my car, including a door ajar… i haven’t seen many problems w the footwell module and the door ajar but they got everything fixed my 335 is back in business
