Sorry to bring back such an old post, but I had some questions.
O2 sensors read differently pre-turbo because of exhaust pressure right? They are designed to be on N/A or post-turbo pressures. Does the AEM setup adjust for this with an exhaust pressure sensor? From your post it sounds like it does, I was just curious. I'd like to know what adjustments have to be made due to pressure.
This could be quite handy on a single turbo system on dual banks, like a boxer or v6/v8 engine where you normally have to read the AFR post turbo, when one bank's exhaust travel is much longer than the other.
