Everything with the ecm works great but… Everything with the ecm works great but when I put a scan tool on it found that it was programed with a different Vin so I emailed support and the responded and ask what it was showing and what the correct Vin should be never got any email back and waited a week and emailed them again with everything and never got a response

Jeep Grand Cherokee 2007 worked PERFECT I have a Jeep Grand Cherokee, 2007, which are known to have ECM problems. I send my vin number to them, and they send me a programmed ECM specifically for my car. It really works ABSOLUTELY PERFECT. It was really plug and play. I did print out the instructions, on how to install it for my mechanic, and he installed it exactly as described. He didn't even need a scanner, since when it was placed, and after the soft reset, it worked immediately and perfect. I am so incredibly happy. Thanks guys from MAKS, my car drives like a new one!

Had some issues and they stood behind… Had some issues and they stood behind product, if I need a pcm or trim I can with confidence do business with them very good service

Great company Very helpful when I called. Shipping was a lot quicker than expected, as we are in Canada! Easy installation and setup!! Would highly recommend!!

Highest recommendation for this Company Highest recommendation for this company. I tried the whole of UK and Europe for ECU replacement/repair for Chrysler Grand Voyager 2005. To no avail. Found Mak's online and 100% straight forward. Easy website, chassis No given. Very quickly sent replacement ECU, at a very reasonable cost. Plugged in and worked 1000% with no issues. Thank you so much. I would contact this company 1st if your looking for an ECU/ECM.
