What do these tables do?

Filling in the blanks, This is a list of each parameter I provide and what benefit it may give to you.

Ramp out Torque Rate @ 40Mhz

  • When Traction control kicks in, this is the rate that the engine torque is added back in.
  • Available through HPT support as [ECM] 26461

SCIAP Linear and Offset

  • Available through VCM editor
  • This will give you the ability to change the Linear and offset for the SCIAP Sensor
  • Truck’s by default already have these values set, Camaro/Corvette will need these adjusted to add a SCIAP sensor successfully

Manifold Volume + BTM disabled by TCS are both available via VCM suite, but I can locate them if requested.

Rich Decel Enable Switch

  • with rear O2 sensors removed, this fixes the glitch with short term fuel trims.
  • Available through HPT support as [ECM] 26462

Vehicle Over speed Torque Limiting & Control

  • These two tables define maximum torque limits based on vehicle speed
  • In some high horse power Strip vehicles, these two tables will limit power
  • Standard practice is to max these 2 tables out
  • Available through HPT support as [ECM] 19049 and [ECM] 26460

Throttle Area Vs Throttle Position

  • This table defines the percent area of throttle body at each throttle position
  • Used mainly on Truck platforms to prevent sudden throttle opening
  • Available through HPT support, [ECM] 26414
    • Note: The way HPT defined this table makes it cumbersome to adjust

Throttle Max Area Vs Manifold Pressure

  • When adding a larger throttle body it is important to update this table to match
  • Available through HPT support, [ECM] 26416

Force CLO Disabled Switch

  • This will disable Closed loop fueling when enabled.

Commanded Power Vs VSS and Axle Torque

  • This table converts Driver requested Axle torque into a Engine Torque request
  • In vehicles that utilize Driver demand tables that use Axle torque, this table is needed to allow the engine to provide more torque.
  • Just bumping an Axle torque based Driver demand table will not instruct the engine to provide more Engine Torque
  • This parameter can also come with a switch to enable/disable axle torque driver demand tables.

Engine Noise Tables

  • This Set of tables includes the Expected engine Noise tables
    • includes Table to change the airflow Axis for all knock tables
  • This is different than the Knock tables already provided in VCM Suite

Engine Friction Table

  • This table provides ability to change how much friction is needed to turn the engine
  • Can play a role in fine tuned torque settings.
  • Includes Supercharger friction table as well

Desired Oil Pressure Tables

  • This table defines commanded oil pressure.
    • Desired Oil Pressure Base
    • Desired Oil Pressure High Load
    • Desired Oil Pressure Hysteresis
    • Minimum oil pressure vs RPM and Temperature
      • I have not yet seen this table in VCM suite
  • As of today, Hpt has most these tables,
  • Available as [ECM] 28332, 28333, 26410, 26411, 26412

Barometer Tables

  • On SCIAP Vehicles, there is a set of 3 barometer tables 65/85/100kpa
  • This set of tables relates current barometer and manifold KPA and engine speed to output a reference barometer for the fueling calculation
  • This table is not needed for normal sciap setups, but it will allow the vehicle to drive a ton smoother.
  • (not available on 2014 vehicles)

SCIAP P101 performance Table

  • This table maps the maximum airflow to SCIAP inlet pressure delta
  • This is the common culprit to P101 and P1101 errors when adding SCIAP sensors
  • This table comes with an maximum enable Pressure ratio parameter
