What People Say

DiMatties Automotive
I tried 4 PCM rebuilders before the owner of the car found your site. I needed a Body Control Module for a 1995 Chrysler. I talked to a tech named Bono and he told me that the BCM was already programed and ready to go. From now on this will b the only company I will deal with on PCMs, TCMs and BCM. DiMatties Automotive

We had been looking for an ECM for our 2006 Chrysler Sebring. We had been quoted $400 by almost all dearships and parts stores, when I happened upon Flagship's site. I was able to purchase it here for $140. Amazing! And it was guaranteed and preprogrammed. Love this company. Amazingly helpful and efficient customer service.Thank you so much.

I ordered a ecm for my 2007 Cadillac Escalade EXT. The computer arrived well wrapped. I plugged it in and it worked. The only thing I had to do is get the crankshaft sensor relearned. Excellent service!!!! I would highly recommend Flagship for anyone that need a computer for their vehicle. By the way, the issue was reduced power, service stability track, traction control off. Giving code P0641.
Scott Monagle
I was stranded in Florida with a van that had all sorts of issues. After self-diagnosing the PCM (and flying home), I was able to order the PCM from FS1. The product is excellent. When I returned 6 weeks later, I installed the PCM and drove 1200 miles without any issue. I cannot thank them enough for providing a part that was many times cheaper than a dealership wanted.
Doug Webber
Would buy from them again. Purchased my PCM and with the VIN # I provided they contacted to let me know I had selected the wrong one and corrected my order for no extra charge. Had my computer in less than a week from the time of ordering. Plugged in and fired right up fixing my issues.
Mitch Hathorn
I have rarely had the opportunity to say "I'm IMPRESSED", however Flagship One earned my respect. Delivery was as promised, the computer was an exact replacement for mine and the truck started right back up.
Phyllis Hansen
This is an amazing company with exceptional customer service. We placed an order. I received an email with installation directions, another with warranty information and yet another, personalized email giving me my tracking information. With all the on-line shopping I search for the customer service. Flagship One, Inc. is now our go to company.
John Cortez
Just received my ecu for my dodge charger. They let me know every thing that was going on! Got mines in the mail last night . installed and. Couldnt be happier! Thanks flagship 1! Highly appreciated! Thanks for being in business in these times!
Brandon Harvey
ECM came programmed and turn key ready for my vehicle. I'm very happy with the product they sent me. They even communicated to me that I ordered a more expensive one than the one I needed and they refunded a portion of my payment. I would give them 6 stars if possible.
Adam Curtin
Bought ECU for my Cadillac CTS. Replaced it myself with no experience and it worked well. I'd recommend it. Saved me at least a couple hundred by doing it myself and it wasn't too difficult.
Charlies Creech
Jeep had been sitting around for years and no one could get it to run. My dad and I diagnosed it, thought it needed a new PCM...ordered one up from Flagship and popped her in and it started right up! No complaints from me! Awesome service and awesome product.
Rapco Automotive Centers
great customer service, we purchased 2 ford computers within the last couple of months & everything went smoothly, no problems at all & computers were already programmed & one came with keys that just needed to be cut & synced to the pats module which was able to be done with our snap-on scanner. thanks again for the great service.
