ECM arrived programmed with the wrong… ECM arrived programmed with the wrong year after supplying them with the VIN # Drove about half a mile and ABS light and brake light came on. Also the rear defroster light started flashing and the A/C light will not come on and I can’t change the position of the blend doors for the heat. It only blows out at the position where it blows air onto your face. Very disappointed . Very disappointed. I returned the ECM immediately

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!

AS AN AUTOMOTIVE REPAIR SHOP OWNER.... I OWN AN AUTO REPAIR SHOP. HAVE TRIED SEVERAL ECM COMPANIES IN THE PAST, TO BE DISAPPOINTED IN ONE WAY OR THE OTHER. SO FAR, MAKS HAS BEEN GREAT ON PRICE, EASY TO CONTACT, AND DELIVERED A QUALITY PRODUCT IN A VERY REASONABLE AMOUNT OF TIME. MOST DEFINITELY WILL USE THEM AGAIN IN THE FUTURE.

Record time Shipped out in record time, was initially told it was in backorder, but they expedited my order before the holidays came around. Now that’s great service.

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
