I decided to address the Spark Retard first, then main shift tables, then pressure multipliers/modifiers.
Tune #
6.3 - Zeroed Trans TM and Abuse Tables - has no transmission TM
6.4 - Engine side of TM - Zeroed Spark Retard vs Torque Reduction table
6.5 - Zeroed both Normal and Performance Shift Time Tables - Desired Shift Time vs Torque Tables
6.6 - Adjusted Upshift Line Pressure Normal and Performance tables - 90psi from 240TQ up, and then interpolated between horizontal lines between 0-240TQ
6.7 - Zeroed Upshift Pressure Multiplier Table
6.8 - Zeroed Upshift Pressure Modifier 1>2, 2>3, 3>4 tables
Per 6.7 above - Should the Trans>Auto Shift Properties>Shift Pressure>Shift Pressure Modifier>Pressure Multiplier table be set to "1" in all table cells, instead of zero? Reason I ask, last part of the table description says Increasing the Multiplier firms the shift. 1 = No Change.
Do the above steps in tune changes make sense? Or should I do one, before I do another?
Almost seems like I'm taking this 4L60e back to the stone age,......:cool:
Thanks Fellars
