okay so i've had the accessport since it came out and it was awesome... but recently my car has "died" while i've been driving. The car basically shuts off, i have no power steering or breaking and i would have to pull over to the side, shut off the car and turn it back on... i reflashed it back to stock and it didnt do it anymore but when i change it back to the stage 1 it would happen again. anyone have this experience or know why its doing it? oh and my CEL came on with a code P0037. H02S heater control circuit low bank 1 sensor 2.

 

Do you have any other mods?

 

i have a mbc set at 22psi, UR testpipe and a cone filter

 

You need a custom tune not an off the shelf map.

 

I did not think the current off the shelf maps on the AP were meant for cars with mods. Espcially the MBC. Connect Cobb to verify this, but I think those mods are your problem. You will either need to take them off or take your car and have your AP custum tuned.

 

The AP cobb map is for a completely stock vehicle, no intake no exhaust nothing.

 

when does the car die? for example in 5th gear on the highway, putting the car into neutral? if so that is a common problem with a lot of cars running intakes. but what the others said, the stage 1 cobb map specifically states stock intake to run the map

 

coming from 2 prior APs before my X AP........the AP sets boost, thus NO MBC is meant to be used with it, also depending on the stage, some mods will be ok, def not a MBC however

 

so if i have a catback exhaust i shouldnt get a accessport?????

 

No... It just means that the stock maps provided by Cobb are only for completely stock vehicles... or at least the current Stage 1 maps are... Stage 2 apparently is a little more lenient and, from what I understand, generally requires a catback and sometimes even a pill?

 

The funny thing is that this topic has been discussed numerous times before and how stage 1 map is for stock car only and that even a drop in is not recommended currently, much less other mods!

 

+1. I'd start with removing the MBC first and trying the the Cobb Stage 1 again. I believe that's your culprit.

 

You might be ok with a catback. But COBB recomends a completly stock vehicle. If you have a a/f gague you can play around with parts and see if they are leaning the car out too much.

 

so my car died again today.... i flashed it back to the stock reflash and thought that would stop the car from dying but apparently something else is causing it. Everytime the car has died its normally been when i'm slowing down on a little hill or a little decline in the road.

 

make the car stock and bring it to the dealer if all else fails. what exactly is on the car with the stock tune?
