Once you bring SD into this then your on your own, I am not on the SD cool-aid trip and in no way can SD adjust for changes of conditions
I know.
I once wanted to see what are the fuel trims in SD (that was about 2% less than with the MAF).
I now wanted to check the function of the MAP forcing the PCM to run in SD, just to see if after the cleaning I was able to see similar fuel trims as before.
The fuel trims are the same and that should mean that the MAP is OK (I wasn't sure if the cleaning liquid was safe for the membrane inside the MAP).
