I have had my port for over a year with no problems. I recently got pro-tuned at a shop i won't mention because i have yet to contact them about the problem i am now having. I valet parked my car last night and switched to valet mode. my car suddenly died while i was idleing getting ready to hand her over to the nice valet. I tried starting it back up and it wouldnt start. It was acting as if i had put it into anti-theft mode. I had no choice at the time but to reload my stage 2 map so i could get it started and have it parked. This morning i went out to try it again and got the same results. This is where it gets confusing. I then turned the key completely off and tried starting again without switching out of valet and it started like it should. I took it for a drive to see if the rev limit on the valet mode was indeed working and it wasnt. So then i switched maps to anti-theft 1 which is supposed to not allow the vehicle to start. Tried starting the car and it wouldn't, just like its supposed to work. Again i turned my key fully off and then on again without switching out of anti-theft and the car started right up. After a few more similar tests i have come to this conclusion... Everytime i turn my car fully off the car is reverting back to my original stage 2 base map. This along with the fact that the valet mode is completely borked. Basically my map swithing capabilities are completely useless because everytime i turn off the car it reverts back to the base map. Wondering if this has happened to anyone else. I have used both the anti-theft and valet maps before the protune and had no problems what-so-ever. The only other new addition to my car before i discovered this problem is an amplifier which i installed, correctly i believe, with the power wire straight to the battery and the remote switch to an "add a fuse" in the sub-fuse panel behind the drivers side dash. So... any thoughts? I will be contacting both Cobb and the tuning shop first thing monday.
