List of Verified and Reliable PCM/ECM Rebuilders

Auto Computer Specialist took care of me properly. They opened the PCM and looked it over and supplied me photos of the damage. They condemned my PCM and had a new PCM ready to go shortly afterwards. These people are wonderful to work with and well worth the phone call to have them take care of your ECM or PCM repairs.

STAY AWAY from car computer exchange at all cost!!! hand delivered a PCM there, called back 2-3 days like they requested only to be put on hold and ignored. Went back in person only to be ignored in person, not even acknowledged at all while I stood in their office (at this point I have read all the horrible reviews and know without a doubt I have been screwed). Well today, nearly 6 months to the day of the PCM being dropped off I get a call wanting to know "if I still want to do business" and that my "PCU tested fine" and "for $100.00 I can get my PCU back". So, I went back got my PCM in my hand said a smiling "Thank You" and walked right out. Now, my PCM is damaged/bent at the corners where the screws hold the 2 pieces together and also missing 2 of the screws. So, that is my experience with car computer exchange. I advise to stay away from them at all cost. 

Add my truck as another success for Auto Computer Specialists.

I shipped the ECM to them on 9/23 by UPS truck.

I listed my symptoms and the trouble code and they were able to fix it for me.

I received my repaired ECM on 10/13 and test drove the truck today.

They are the same company as Auto Computer Exchange and gave us the run around with ecms for an 02 cummins for a year. blaming the problem on our wiring, and then eventually after we spent hours testing said they can fix it. so we send them their computer back and they send us the same computer with nothing changed same issue. Finally got them to send a computer first, then sent them theirs to ensure we get a different unit. Previous problems now fixed and the truck is somewhat drivable, however the crank signal to the PCM dies occasionally, verified this loss at the ecm connector so it is not a wiring issue. they now refuse to help and we are out 1000$. Going with crites as he was helpful over the phone. will report back with the results.

Excellent information Pepsi, thank you

Auto Computer specialist really helped me out in a big way.  My ECM went out 500 miles from home on the side of the interstate.  I got the truck to a shop and we narrowed down the problem to the ECM.  After finding this page I called Auto Computer Specialist around 2pm and told him my predicament.  He expedited his service and had an ECM overnighted to the shop I was stuck at.  We received it from UPS around 10am the next morning and I was back on the road within the hour.  I can't thank him enough for helping me get back home as quickly as possible.  I'm a customer for life.

after reading this vendor referral I decided to go with a company that is not on this list I went with Mintt engine control module as they were new and seemed promising ill keep you guys updated  https://mintt.com/.  Nothing but great things to say about this company 

Auto Computer Specialist came through for me. I had another vendor try to rebuild my ecm, after going through 3 ECM’s from undisclosed vendor with no luck I sent all 3 to Auto Computer Specialists and ended up with a top notch ECM allowing me to get my truck back on the road after 3 months of frustration and stress from another vendor. Auto Computer Specialist provided me a complete list of what was found, what repairs were done, and possible causes. 

One week after installing repaired ECM on my stock 1999 2500, everything is great at this early stage.  I went with

https://autocomputerspecialist.com/  after reading this vendor referral.  Nothing but great things to say about this company and it's communication with the customer.  After describing my problems to the company rep on the phone (delayed / no Wait To Start light, lost lift pump power supply, and engine cranked and had race car cam lope at idle then die 15 or 20 seconds, and dead fuel pedal), the rep talked me into a repair rather than a purchase, saving about $300.00.  Total cost after I shipped to them was $315.00.  Replacement cost was quoted at $600.00, which they had in stock.  Turn around time was about 5 days from me to them, and them to me.  Highly recommend this company.

I've been dealing with Autocomputer Specialists due to the above ranking. I initially called them Monday the 19th of October and ordered a new ECU because mine went bad. I ordered from them instead of sending in my computer to repair, as the repair is time sensitive. I'm advised on Monday by Daisey that 1-3 day turnaround and then it will ship. I called back Wednesday the 21st (Spoke to "D") and was advised that they had just gotten the unit from their distributer and they were going to charge me, $300 that day. Supposed to ship by Friday and to await an email. Friday the 25th at 4:30 local time (Spoke to "D" again) I call them again because I hadn't received an update. He states that they will not be shipping it that day, but he would overnight it due to the trouble. Monday the 26th at 5:20 local time (Spoke to "D" again) I call to find out something, he tells me they just got the unit in and will probably ship Wednesday. I ask D why he told me Friday that it would ship that day, he places me on hold until 5:35 and then hangs up. Today the 27th I received an email, stating they had emailed me previously about the delay. I look at the email, and it's obvious that they copied someone else's email and then changed a few parts. 

Avoid this place at all costs. I have a feeling I will have to file a BBB complaint for fraud, all while still not moving toward having my car fixed. Included is the email, where you can see the edit they made and how this is not an email that was sent to me.
