    Well...

    VTEC controllers essentually tell the ecu when to engage VTEC, but the ecu has to be programed for VTEC. Otherwise the VTEC controller will tell the ecu nothing. So sadly, no it wont work. Seriously, save up the extra money for a Hondata system. You can tell it anything you want to do.

    If you're building an LS/VTEC and considering using a piggyback hack to run the engine then I'd imagine it's probably a piss poor build...

    I wouldn't consider it, just run a VTEC ECU and/or get a chipped/converted ECU. VTEC will still engage with a VTEC controller but fuel and timing will not be optimized for that secondary cam profile.
