Anyone else chaing their maps now that warm weather is upon us? I now have another piece of evidence pointing to the fact that there are different stock, open loop maps for different operating conditions. My cold weather CZ map hardly worked at all now that ambient temps are in the 70's. What resulted in a nice 12.5 AFR before was now way lean. I had to go WAY richer on the CZ map to compensate for the new open-loop map that the stock ECU is using.
