I am using nearly all OE sensors, along with OE coils and injectors. However, the factory MAF is now used only for air inlet temp because we are using an AEM MAP sensor. We are also using the AEM wide-band O2, the stock O2 is gone.

Okai so if you are still using the stock ECM to run your drive by wire TB, this is because the EMS cannot by itself?? I have an 2005 echo, so my TB is the drive by wire...

Is there any other reason for you to keep the stock ecu installed?

Thanks very much for your fast informations!

Also, what about the wiring kit needed? Do you guys used the big 96'' with the relays & fuses?
