Qcwo Reviews 

Très professionnel, je vous le recommande. Rapide et colis reçu avec succès.

Richards's computer repair service was fast and worked when installed. Although it did not fix my RAV4's surging on acceleration, it did not induce more problems. As an electronic tech for 40 years, that is a huge plus when troubleshooting a problem. I had to resist the urge to open the box to see what was done but those pesky tamper seals :)
Over all I will use him again if the need arises. +++

Several local mechanics have checked this 2003 RAV 4 for poor shifting, misfiring and failure to start. Even the transmission shop could not find any issues. I was prepared for an expensive tranny rebuild.
Fortunately I found this website which identified the issue as a faulty ECU.
Shipped the Rav4 ECU to Richard for repair and voila! All good!
Thanks Richard!

My experience is just like most of the other reviews. I’m perfectly happy with Richard’s work, communication and speed. The entire process took about a week and was successful, I wouldn’t hesitate to use his services again.

They has quickly become my favorite online store for technical car parts, and here's why. My BMW needed a new transmission control module, and after checking various local shops and websites, I found that they had exactly what I was looking for, at a far better price than other sellers. The product listing was detailed and made it easy to ensure the part was compatible with my vehicle. Ordering was straightforward, and the part shipped out almost immediately, arriving at my doorstep in just a few days. What impressed me even more was the quality of the part-it was packaged securely and worked flawlessly right out of the box. After installation, my BMW's transmission issues were completely resolved. I also had a quick question about the installation and their customer service team was incredibly helpful, walking me through the steps and offering additional tips. It's rare to find a company that combines both quality products and outstanding service, but thy do exactly that. I'll be a repeat customer for sure, and highly recommend this site to anyone in need o technical car parts.

The ECM fit perfectly, and shipping was lightning fast!

I bought a chip for my Honda and couldn't be happier. The part was reasonably priced and arrived quickly. It was easy to install and worked flawlessly. They are now my go-to site for technical car parts. Highly recommend them for quality and reliability!

I was having a tough time finding a replacement engine control module (ECM) for my Chevrolet Silverado at a reasonable price. After searching multiple websites, I stumbled upon this site, and I'm so glad I did! They had the exact ECM I needed, and the price was much better than what other sellers were offering. The shipping was super fast, and the part arrived in pristine condition. After installation, my truck started running perfectly again. The site also offers a great selection of other technical car parts, so I've bookmarked it for future purchases. Plus their customer support is top-notch, helping me confirm compatibility before placing the order. I'll definitely be recommending them to my friends!

Prices are competitive, and the website is easy to navigate, with detailed product descriptions that help you find the right part.
