Thread: Let's Talk TCC Lockup

  1. #1

    Default Let's Talk TCC Lockup

    I have everything working. The power band for the car is about 3000-6000.
    I set the lockup at 2750 and 15% TPS, so if I'm on the highway cruising about 2500 RPM it's not locked, when I put the pedal down it locks up.
    Seems to be happy there and doesn't do the lock/unlock jitter. Any ideas on how to tweak the converter lockup?

    It's just something that needs to be experimented with.

    I realize the Basic I/O (System ICF) has basic Torque Converter Clutch Lockup
    parameters, but you don't have to use it (especially if you have a VSS sensor).
    You can create a TCC Lockup Output (in I/O) and configure it to operate from up
    to five Sensor Input Triggers, with Secondary Deactivation - Hysteresis/Range modes.
    Some find it beneficial to incorporate vehicle speed into their TCC Lockup parameters.
    A relay must be used because all the ECU's Outputs are rated at a maximum of 2 amps.

    If the I/O menu icon (ICF) isn't already uploaded (added) to the top Toolbar, follow these instructions:
    (This same procedure applies to all the various Individual Configuration menu icons/items.)
    The "I/O" function is an "Individual Configuration" of the Holley EFI software.
    At top of screen, Click "Toolbox" and "Add Individual Config".
    At top of new window, select "Individual Configuration Library".
    At bottom of new window, select "Holley EFI Inputs/Outputs Config".
    Select "I/O" and open "Base Config - Blank.io".
    The "I/O" icon will then be present at top of screen.

    To connect up to 4 Inputs & Outputs to the EFI main harness, use I/O Auxiliary Harness 558-400.
    Eight Wire I/O Auxiliary Harness Connector Pin-Out (also in the Holley EFI Wiring Manual Link):
    Pin A...A12...White/Blue (Input #1)
    Pin B...A3...White/Red (Input #2)
    Pin C...A13...White/Black (Input #3)
    Pin D...A4...White/Green (Input #4)
    Pin E...B12...Gray/Yellow (Output #1)
    Pin F...B11...Gray/Red (Output #2)
    Pin G...B10...Gray/Black (Output #3)
    Pin H...B3...Gray/Green (Output #4)

    The 558-400 I/O Auxiliary Harness is 20 feet long, and it's "plug & play" into the EFI main harness.

    Interesting take Danny. Using other parameters to signal the TCC lockup. Hmm...now you got me thinking.
    I have a 700R4 with a VSS which I'm running to a Dakota Digital box to run the speedo. I believe the VSS can be split, but I'm not positive on that.

    Yes, that won't be a problem with a Hall-Effect sensor.
