Very Interesting! I might be in the market for this device soon. From what it looks like this device plugs into the obd port? You program the car then remove this device , or does it stay? Or does it not go on the obd port?
Yes it will.
The idea is that you need to do 2 readings with the stock cats, the unit stores these readings and then after you put the sports cats back on, the unit will simulate the original readings from the lambda densities and it will trick the ecu, thinking that you still have the stock items on!
Not sure about price yet.
