We have used this company before and was informed that this is the best choice for ECU's.
I ordered and it arrived in 4days.
Installed it, ran the vehicle and had ZERO issues.
Will definitely be back again

Corrupted Drive
February 12, 2026

I ordered an ECU for my 09 Silverado. It got to me relatively fast, but once installed would never turn over the truck. I had a mechanic look at it and was told it was corrupted before it even got to me. Good thing my old one still works, the one I ordered would have left me stranded.

Shipping was great
February 11, 2026

Fast and efficient! Plug and play like they said. I still had one issue and it wasn't the computer. I had a blown fuse that caused it not to start, but once I replaced it fired right up. Had a few codes but that was because the car sat for a little while. Live the product though! Worth the buy! Thanks flagship one!

Had an issue with my 97 4l60e transmission that 3 reputable mechanics could not repair due to an ecm problem. After using the local parts store ECM and a GM dealerships programming, still tge problem was not resolved. Flagship pre-programmed me a new ECM for plug and play with key relearn using just my vin number, shipped it within a 3 day window from NY to GA, received it in 2 days. Fixed my problem immediately. An awesome, awesome company to deal with.

Great Service!
February 9, 2026

Nelea was so helpful when I called in and asked about the part I needed for my car. She was patient and answered well my questions. She gave me status updates when my part was done w/ programming. She even called to follow up if the part was working correctly when installed.

Very satisfied!

Thank you, Nelea! You're the best!

Defective Ram PCM
February 9, 2026

We at Aroostook Auto Tech have used FS1 many times over the years for pre programed PCM. I can honestly state that I believe that we have ever had a problem. Several years ago a gentleman that had never been to our shop called about a Ram that he couldn't get to run.We diagnosed it as needing a PCM and quickly realized it had a new reman from FS1. We contacted your great service staff and they quickly realized that they had recently provided our new customer with the new unit. With out having to return it to be checked out you promptly sent out another piece so as to get this gentleman back on the road. We sent the unit back in to have it checked out and turned out it did indeed have an issue. Long story short your great organization made what could have been a $#*! show for our customer easy as most of us could have ever expected. Again thank you and all of your dedicated staff for making our lives much smoother. Thank you Mitchell Holmes President Aroostook Auto Tech.

Sufferring for years

Finaly found the right place, just hoping not to have to use the lifetime warranty. The only complaint is the sand blasting material that comes with the computer otherwise one week and my car is running like a top.

Integrated power module
February 7, 2026

Very professional! Verified all the information three times, honored their advertisement matched any price lifetime warranty. And was very helpful with presenting the information to flash and program to the VIN number for the integrated power module, the rap that works for the company. Rosie was very professional.
