ECA PLUS
SUMMARY
- Built on TRP’s proven CAN bus Ethanol Content Analyzer platform
- Adds support for up to three additional analog sensors (0-5 V inputs)
- Weather-sealed, carbon fiber infused enclosure with DTM 8-pin main connector
- Three DT 3-pin connectors with dedicated +5 V, Ground, and Signal pins
- Includes TRP Universal Flex Fuel Sensor Harness (6′ sleeved + 2′ pigtail)
- Optional TRP Universal Sensor Harnesses available for quick plug-and-play with aftermarket pressure sensors (TRP, AEM, MoTeC, etc.)
- Includes three DT 3-pin connectors with pins, cavity seals, and connector seals to be used as receptacle seals for inputs not being used or to make your own sensor harnesses
- Configurable CAN bus speed (500 kbps or 1 Mbps) for maximum compatibility; 500 kbps is most common
- CAN bus settings that are consistent with other competing options on the market to prevent from needing a retune if upgrading to our product
- Motorsport-grade wiring and epoxy-sealed housing, safe from heat, fuel, grease, and harsh conditions

ATTENTION TUNERS
The TRP ECA PLUS is designed to match the CAN data structure of other products on the market. If you’re upgrading or replacing that competitor’s unit, no retune is required — simply swap it in and go.
The TRP ECA PLUS outputs a CAN signal with the following specs:
CAN Bus Specs
-
CAN Bus ID Standard (11 bit)
-
CAN Bus ID (HEX): 0x0E1
-
CAN Bus Speed: 500 Kbps or 1 Mbps (configured at checkout)
CAN Data Layout
-
Byte 0 – Flex Fuel Percentage
-
8 bits
-
Range: 0–255% (0–100% ethanol is exact, 0.01 multiplier)
-
Example: Decimal 70 = E70
-
EcuTek Note: For many platforms, the software expects 0.0–1.0
-
-
Bytes 1–2 – Analog Sensor 1
-
16 bits, little endian (lo byte first)
-
Range: 0–5000 mV (saturates at 5000 mV)
-
Conversion: Raw × 4.8876 = mV
-
-
Bytes 3–4 – Analog Sensor 2
-
16 bits, little endian (lo byte first)
-
Range: 0–5000 mV (saturates at 5000 mV)
-
Conversion: Raw × 4.8876 = mV
-
-
Bytes 5–6 – Analog Sensor 3
-
16 bits, little endian (lo byte first)
-
Range: 0–5000 mV (saturates at 5000 mV)
-
Conversion: Raw × 4.8876 = mV
-
-
Byte 7 – Flex Fuel Sensor Status
- 8 bits
-
0x00 = Sensor OK
-
0x01 = Sensor Fault
