Both for the by-pass air control solenoid valve were different than the pinout. B62/2 was very high (14V) and B62/1 was very low (1.5V). This is the Idle Air Control Valve, right? I will check this again, as well as the neutral switch and parking switch, with both read 4.7V, instead of 0 or 8.

It is unlikely to be a problem with the ECU or the stage 1, but we are running out ideas. Since you are a customer of LAN, and he is the ECU expert, I suggest emailing him to ask for an opinion.
