Long story short, I was datalogging via DataMaster, but then I got a new computer and found they'd discontinued it. TunerPro is about the only alternative, so I've been trying to use that. 20+ hours in, and I still can't get it to connect. If it gets past "DA: connecting" it starts getting all sorts of datastream errors, which as I understand it are from chatter from the ECM/CCM modules. I've tried CaptainKawasaki's ADX from Gearhead EFI, two others I found on the $8D thread here, and several from TunerPro's website. I'm using a 1320 Electronics bluetooth ALDL cable, my car is a '90 Corvette, and the ECM is the 1227727 (which seems somewhat of an odd combo; most ADX files I find for a '90 Corvette are for the 1227730 ECM). Does anyone have experience with a similar setup? I'm pretty much at my wits end trying to figure this out. I'm pretty techy so I tried to figure out the ADX file, but there's pretty no documentation available explaining the language.
