I can now confirm that you cannot get the c a t monitor to show ready in order to smog the car when you run the jb4 mhd back end flash. I flashed the car to stock and set the jb4 to map 0 and had to install the stock 2.5bar map sensor and the c a t monitor became ready with in 10 miles of driving.

so in conclusion in order to pass California smog besides the visual test. The car must be on the stock flash and jb4 must be on map 0. You must be useing the stock 2.5 bar map sensor. There must be no check engine light and all the monitors must show ready or some can say not available. Monitors cannot show incomplete or fail.
