Hey guys, so I have a 2020 Supra with 700 miles, and I bought my bootmod3 cable. I try uploading the stage 1 93 tune, and it always gets to 93%, then starts clearing the primary codes, and then secondary codes, then it will fail. The car won’t even start, so I have to upload the stock file. Any one have any info on what’s going on? The battery is Brand new, so the battery is definitely alive. I’m a little confused. I even tried uploading a standard map with no customization or nothing. I also disabled all the firewall stuff. Here’s the error.
