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!

They fixed it when the dealerships wouldn't help. They found the problem and were able to sell me a rebuilt ECM faster than they could fix the old one. The van started up immediately and 400 miles in I haven't had any issues. I did need to call to address an issue and the people answering the phones were polite, helpful, and seemed to really care.

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
