I'm brand new to tuning. Just picked up a DHP tuner and downloaded the software this week.
I cant register the cable no matter which COM Port (1-16) or either bps setting combination I select. Could this be because I have a ZZP tuned PCM? I have read that it may be locked. I have my original PCM, but it would be nice to have the zzp settings since I only need to change my injector size.
Any advice is appreciated
