Review on 🔍 LAUNCH CRP129X OBD2 Scanner: Advanced TPMS/Oil/EPB/SAS/Throttle Reset + New 2022 Features, Lifetime Free Wi-Fi Update, ABS SRS Transmission Check Engine Light Code Reader, Auto VIN, Battery Test by Jamie Masloski

Item shipped quickly, was packaged very well and worked great. After getting an A/B throttle position correlation code on my 2011 Tahoe, I purchased a new throttle position sensor and replaced and cleaned the throttle body at the same time. Now there is a problem with high idle (2800 rpm). I've looked everywhere for a solution without going to the dealer but to no avail. Then I found this CRP129X OBD2 scanner diagnostic tool and it said it will do a throttle relearn. I was a bit skeptical, everything else pointed to either paying the program vendor or buying several thousand dollars worth of tools. I received the item, did a firmware and a few software updates to the instrument (these guys seem very good at updating), connected to my Tahoe, did the relearn process (only 30 seconds) and now it's idle like a champ It's been a few weeks and the Tahoe still runs like new. Thanks, people. I also loaned a tool to one of my colleagues and he hooked it up to his wife's BMW, updated a few things and he says the car hasn't worked this well in years (I don't know what he actually did , but he was very grateful to be able to lend it to him).
