Karman Auto 4943 Northeast 105th Avenue, Portland, OR 97220

"Texted with Dan about cloning a Mercedes ECM. He responded quickly and said he could do it. I paid $199 on the website and sent my ECM and donor in. It was returned within a few days. However, the donor ECM was not cloned completely. The VIN was not coded, only the security hashes were coded. The car did not start. I texted Dan on five different days, November 17th, 20th, 22nd, 27th, 29th. I was asking if he could complete the job I paid for. He never responded. No communication. He responds quickly to make the sell, but no customer service afterwards. I issued a chargeback with my credit card. I don't recommend doing business with this company. In one of the pictures I posted. You can see the original vin at the top read from the original ECM. At the bottom you can see the vin for the incomplete cloned unit. They are supposed to match. They don't."

"Karman Auto is fantastic! I had a problem with the communication between the dash and BCM on my GMC Canyon. Karman Auto fixed the problem when the dealer said it couldn't be done! Additionally, their turnaround time and communication are second to none. Shipped my modules to them from Ohio and they had them back in my hands in no time, and in perfect working order. I will be recommending to all my friends! pleasure doing bossiness with you Karman Auto."

"Dan is the man! Took my Mazda 3 in for work they did a great job and at a good price! I recommend them!"

"I needed an expert to help diagnose an electric problem and they were able to when the dealership told me it was impossible. Save yourself time and money by going to Karman first."

"I have a 2003 Dodge Ram 2500 that had an issue with the airbag module which caused the light to go off and throw a code to the effect that the driver’s side pretensioner squib was shorted to battery. All of my probing and testing with a multimeter revealed that nothing was out-of-spec. I ordered an identical module off of eBay because that part was discontinued in 2019 (Thanks a lot Chrysler!) and installed it only to find out that it was not configured for side air bags. I sent my original module and the module that I had just purchased to Karman, and about a week or two later, the module came back properly configured and worked perfectly with no airbag light."
