Summary of change:
The Toyota 20v 4A-GE Idle Air Controller uses a two coil solenoid. Thanks to MembersPage/Skassa we have a working configuration that should work 'off-the shelf' with 20v installs, providing us with a perfect idle. Download the Patch zip file from here: http://vems.hu/www.vems.co.uk/VEMSConfigs/4A-GE20vIACPatch.zip Unzip the file into your {{VemsMT1.0.xx}} folder. Go into the {{VemsMT1.0.xx\config}} folder and rename the {{config.txt}} and {{tables.txt}} files as these will be overwritten. In the main {{VemsMT1.0.xx}} folder double click on {{download-config.bat}} Once the files have been downloaded double click on {{20vIACPatch.bat}} You will see a number of warnings, these are expected. As long as there are no Errors proceed to the next step of double clicking on {{upload-config.bat}} Now test that your VEMS is functioning correctly. If you're happy with the changes go back into the config folder again and rename the {{config.txt}} file to something like {{configPre20vPatch.txt}} in order to preserve your original config. Return to the main folder and double click on {{download-config.bat}} This will download the config that you have tested, you may wish to rename the config file to preserve it.
