After applying a patch (e.g., a Speed Density operating system), the tuner modifies the calibration. It is critical to verify the pinout again . If you physically repurposed a factory wire that used to carry a MAF signal to now carry a MAP signal, but you forgot to update the pinout assignment in the software, the ECU will read garbage data, leading to catastrophic engine failure.
