CarBerry Maf Mode + unplug Maf automatically SD-Mode?

I have a question regarding how the CarBerry ROM works: If the vehicle works in MAF mode (set in ROM) and you unplug the MAF sensor, is it automatically switched to Speed Density and the VE map is used? So it's like switching to Speed Density in ROM? I'm asking because I know that on a stock ROM the car can run fine when you unplug the MAF (even without turbo and intercooler) but in CarBerry it runs like crap or just dies. Is properly the VE map wrong or are there some issues with the engine?

Long story short, no. Slightly longer story; Normally the logic to switch to SD is triggered by p102 or p103 (maf disconnected or shorted). With carberry those codes are not functional, so the switch doesn't automatically happen.
