Testimonials

When I'd first contacted Flagship One, my car had been at the dealership service department for a good three weeks and I was getting in a bad way. But it was very good news for me when I found the Flagship One website and ordered a PCM for my '97 Crown Victoria. And, they came through like champs. Once it arrived here I took it down to the service department. I got an email the next day saying that my car was ready to go, and the original problem had been solved. What a load off of my mind. Thanks Flagship One, Inc....

I am a retired Certified Auto Technician. Spent about an hour diagnosing my truck, bad voltage regulator in the PCM. After wasting an hour at a local Dodge dealership listening to them tell me I needed to authorize a minimum of three hours labor to diagnose and possibly replace PCM for over $1000, I went online and found Flagship One. Less than a week and less than $250 my truck runs great. Plug and Play as promised. Great Service!

I own a 2009 Ford F150 my air conditioning was not working and I am one that will always start from the cheapest to the most expensive when I'm working on my vehicle so when I noticed that Flagship had a computer for $144 I had to jump on that although it cost me $70 to get my key reprogrammed and still was worth it so thank you Flagship I also got an extra key with that $70 that I did not have in the beginning this beats going to the dealership and getting a new computer for $1,400

I had no issues at all with flagship one. I ordered an ecu for my 99 durango in British Columbia Canada .delivery was fast and the device works. Customer service was spot on and helpful and the price was good even with the exchange rate I would recommend flagship one.

- Brian Louis

It was so easy finding the correct computer for my mustang. It took just a few minutes to order. I received my computer earlier than it was supposed to be delivered. Every part of my transaction was great! I was able to install it myself and it works great!

- Bradley Lewis

Everything was plug and play. Chipped ignition key worked fine with new computer without any modifications. Everything is running well and no check engine lights as before. Nice piece of mind knowing it has a lifetime warranty, considering the OEM computer was long out of warranty.

- Rick Benson

Gave them my vin number, a few days later my ECM arrived. Installed the refurbished ECM, reprogrammed my keys and it runs like a new truck.
