    Thanks.

    Here this may help some..

    GM's Variable Valve Timing System Performance Test - Hot Rod Magazine

    You'll need a donor PCM designed for a VVT as GM variable valve timing is controlled (phased) with a signal from the PCM.

    Timing is changed @ an optimal time usually under a load only, leaving free rev timing unchanged.

    Power gains will be notable, VVT will be a big difference from the old days of just slipping a lumpy cam into your engine.

    Okay so could i just plug and play with the l92(IV GEN) ecm on an GEN III engine(example: 4.8 or 5.3)? I think the connectors are different. Or does there exist an ecm GEN III with vvt?

    That question I cannot answer sorry.

    I'd imagine there are other engine variables that would need considered.
