Hi. I'm driving an 05 WRX with Cobb Stage 2. Now, everything sounds fine and feels ok, but first, I can't reach the target boost. It's always on mid 14's and when I tried to swap in a new base map, it says Car's voltage is low check cable.

I'm wondering if anyone's got a same problem or is it just my car is bad.

Some advises please.

 

any of the doors open when u get voltage low?

 

Not at all. All doors were closed. And I even turned off every single switch that might affect it, but still. Should it be the battery? Is it possible anyway?

 

i had that prob. b4. i got a bad accessport and traded it in i also cannot hit target boost btw, and i have had mine for about 10 months now.

 

So after you exchanged it, all problems seem to disappeared??

 

Uniquedude, the voltage error code can happen if the car has been sitting there for a while without being started, or if the battery is in need of replacement. Basically, the ECU in your car needs sufficient voltage throughout the entire flashing process or it's possible to damage the ECU. As far as not hitting target boost, have you tried the high waste gate (HWG) maps? If you have more questions, let me know or call our support line 801-713-0035. I hope this helps.
