Defining CAN ECU Presets

Overview

The CCS software has a library of aftermarket ECU CAN datasets (“Presets”) that can be assigned to a vehicle before dyno testing. Assigning a preset lets you:

  • view live ECU CAN data
  • have that data automatically recorded during any test
  • log it for later review
  • export any dyno channel — including ECU channels — to a CSV file at 100 Hz from a Ramp or Drive Test

Each CAN Preset also transmits common dyno channels back to the ECU where supported, such as Power, Torque, and Lambda values.

Defining a CAN Preset is quick and straightforward.

Procedure

On the Vehicle tab (after adding a customer), click Select Presets at the bottom right:

Vehicle Details tab with Select Presets button Vehicle Details tab with Select Presets button

The preset list window opens. Enable the ECU the vehicle has, then click Save to Vehicle. This tells the dyno program what CAN data stream to expect on a given bus — for example, that CAN0 will carry a Haltech V2 stream — so all channels in that standard stream become available in CCS.

Where Preset Data Shows Up

Data Grid — ECU channels from the CAN stream can be shown on a fully user-definable Data Grid page, such as a dedicated “ECU Channels” page:

Ramp Test — chosen ECU channels can be plotted live during a test, for example on a “Ramp Test 2” page:

Data Logging — ECU channels can be added to a named Data Logging page (e.g. “ECU Channel”):

CSV Export — when a Ramp is paused, the dropdown on the Test ID includes a CSV export option, generating a file at 100 Hz containing every channel with the Export option ticked (set under Setup → Channels):

CAN Wiring

Your CCS Dyno is supplied with a generic 2-pin DTM connector, 5 m cable, for ECU CAN connection. You’ll need to make (or source) an adapter cable from the DTM 2-pin connector to the CAN bus in the vehicle — a DTM2-to-DTM4 adapter is supplied as standard for Haltech.

The other end of the generic ECU cable has a 4-pin DTM connector that typically connects to ports 3A, 3B, or 3C on the CAN Hub in the dyno cabinet. On the DTM 2-pin connector: Pin 1 is CAN Lo, Pin 2 is CAN Hi.

  • All CAN ports: CAN Lo = Pin 2, CAN Hi = Pin 3 (same as Motec LTC).
  • Lambda CAN port is the default port.
  • The spare CAN bus is reserved for 500k but can run at 1 Mb.
  • User CAN ports share the same bus as Lambda — 1 Mb, powered.
