How to make OPCOM Scanner working 2021 year vehicles?įirstly you need a good opcom interface with Real PIC18F458 chipfor flash firmware, then you can downgrade or upgrade the Firmware. Nor can it be after-sales because the hardware does not support. If your device does not have pic18F458 chip, please choose our device+software. You are at your risk.įirmware: 1.41 / 1.64 / 1.66 / 1.67 (OCFlash 1.0 – interface flashing tool) Need to flash opcom clone firmware if work with V2021 software. The firmware update to version 1.67 in the OP-COM 200603a program occurs automatically when the program starts. So, tell us the maker and exact model number of the case fans.Attention! OP-COM 200603a only works with original firmware version 1.67. 3-pin fans on a header using PWM Mode always run full speed. But IF your case fans are of the 3-pin type and IF the headers you plug them into are using only the PWM Mode for controlling them, that will not work. Exactly what fans do you have for case ventilation? You have specified the CPU cooler fan as a 4-pin (PWM type) unit, and that certainly should have its speed under control of the mobo's CPU_FAN header. So all fans start full speed, but slow down shortly thereafter. Then, after less than a minute as the POST sequence completes and the actual measured temperatures from sensors become available, the mobo headers' fan control systems slow them all down to whatever is required at that time in terms of temperature. The normal sequence at start-up time for all fans powered and controlled by the mobo is that they start at full speed always. When you reboot and the fans all come on at full speed, do they stay that way? Or, do they slow down after a short time?
