What the hell is a Volo sensor - do you mean a scan tool?
I'm pretty sure (others can confirm) that the VT V8s (Holden Engines) are still OBD1, although they use the OBD2 sixteen port connector.
Hi mate, a volo sensor is a EFIE mapping sensor ( Volo FS2-HHO Edition ). im interested in attaching a HHo generator to my engine through the air intake manifold to save fuel and increase power, but in order to get the gains the hho offers i need to have my sensors recognize that there is also fuel coming in through the air intake and thats what the volo sensor does more or less![]()
Good luck. But remember the old sayings - "a fool and his money are soon parted" and "if it sounds too good to be true it probably is".
