Facts And Questions

1. Does the EFIE HEC Chip Plug N' Play – VOLO come with different plug adapters for different vehicle makes?
The OBDII plug is always the same, but the connectors inside are different. The EFIE chip recognizes which car it is. Old blue HEC CHIP models were complicated to connect without the possibility of PLUG N 'Play and changing the program or settings of other cars ✅ 

2. Does the EFIE HEC Chip – VOLO need to be plugged in permanently after HHO kit installation?
It must be permanently connected, as there is no need for remapping like other software. We prefer the factory setting without changes after disconnecting the EFIE chip ✅

3. Can the EFIE HEX Chip – VOLO be used multiple times for different vehicles?
It can be used indefinitely on other vehicles with OBDII. You need to set up another vehicle ✅
