6.6 Wide Open Throttle (WOT) Downshift Speeds A
There are setting for Wide Open Throttle Downshift Speed settings for both Calibration “A’ and Calibration “B”. These are
used for the downshifts only. Set these to the point where you want to perform a downshift in each gear at 100% throttle.
The speed usually matches what is in you shift tables downshift point. With the RPM calculator, you can verify that the
speed you enter is lower than you upshift RPM. There should be approximately a 1800-2000 RPM delta between the
upshift and downshift Reference Figure 24.
NOTE: This function is only available if it is enabled and you have an RPM signal.
NOTE: In order to use the “Use Lockup Per Gear” setting must be checked. This gives you the ability to set the
TCC Lockup Points for each gear set. This is for experienced calibrators only. More information on these settings
is available in the full manual.
6.7 TCC Lockup Settings
The torque converter lockup settings need to be congured for each Calibration “A” and “B”, depending on what pattern
are being utilized.
The TCC Lockup Flags have setting to keep the converter applied during upshift, downshifts and during coast mode.
Enabling these settings.
The setting to enable control slip can be enabled to allow the converter to maintain a small amount of slip instead of
fully locking. This Feature can only be used on certain torque converters that were designed to run at a controlled slip.
Enabling this also requires conguring the TCC Settings under Setup info folder (see advanced user guide for further
information on calibrating these).
Use Lockup Per Gear. If this is unchecked the Single Point TC Lockup tables are used. This table has just apply and
release points and are used in conjunction with the TCC Lockup Parameters to set the lowest gear to use the apply and
release lines. Reference Figure 25.
