    Default Looking for an experienced tunner in Austin, Tx

    Hi Everyone,

    I'm looking for an experienced tuner to help me with a couple settings on my conversion. I have put an 04 LS1/4L60 DBW into a 95 land cruiser and need some tweeks.

    First: I need the idle to be set to 777 rpm

    Second: The computer thinks the throttle is 100% open when actually the throttle pedal is about 50% down. I need this to be changed to be more accurate. So when the throttle is half way down, the computer see 50%.

    Please call me on my cell, 512-431-8071

    Thank you,
    Jeff

    Hi Jeff,

    Edit: what was the donor vehicle...?

    If you have a Gen III/LS1, then:
    - there is a table for desired idle speed, B4603;
    - your throttle cable is either stretching apart or needs adjustment.

    Ah silly me I missed "DBW" in your post please just ignore my reply.

    Hello Jeff,

    I take it your 2004 LS1 is from a Corvette. The OS, TAC, and APP should also be Corvette variants - to ensure DBW compatibility.

    Where is the wiring harness from ?? Confirm the APP connector is "pinned" for a Corvette - trucks are different.


    Regards,

    I have an LS1 from an 04 Avalance truck. The harness is from PSI Conversions. All components are from the truck.

    Rereading my post, I need to claify that I am looking for someone to do the work for me.

    Thank you.

    Hello Jeff,

    I'm sure someone will offer their services ... I don't conduct any business as a result of Forum discussion ... keeps my motives altruistic.

    Just a point of clarification ... to aid in future communications here, or with your eventual tuner. Trucks were never equipped with the LS1 engine.

    Your Avalanche engine is a 5.3 L .... and is either an LM7 (VIN "T") or an L59 (VIN "Z").


    Regards,
    Taz
