So i was tuning my truck I put a tune in it didn't like so I went to back up a step and put the tune in right before changes and nothing it says failed to connect to PCM. I put a ticket in to hptuners support and gave them the info they needed. They emailed me saying the ABS and the BCM are blocking HpTuners from connecting. Has anyone had this happen and if so what fixed it? I tried pulling fuses to both the ABS and BCM like support suggested and still nothing. Thank you in advance. Also I've used the Mpvi2 on another truck and worked no problems
