Mopar Sucks Imagine my consternation when I found out that I needed a new ECM because my voltage regulator went bad. Then, on top of that, the Dealer would charge an arm and a leg, and the part was 7-10 days out. I opted instead to check the internet and found MAK's where I found my ECM for a reasonable fee, shipped within a day of my order, and pre-programmed! Five Stars, fully recommend

Finding the correct PCM was straight… Finding the correct PCM was straight forward and simple. After I ordered I had a small question and it was answered clearly. Great directions for installation and it has worked perfectly for 300 miles.

Sent a faulty pcm Sent a faulty pcm. Wont stay running. My pcm that I have runs the truck but misfire at idle. The 1 you sent doesn’t even work

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!

Very helpful and professional, problem solved Had many email conversations about replacing my ECM for my 2008 Jeep as the Dodge/Jeep dealership were unable to help me and the part was for a limited release diesel. Took a few months but they found the part, first one did not work but the second one did. It did cost me an extra shipping cost to return the faulty ECM but it works. Mak's was great to deal with.
