DoPe Electrical Specification 6/34
1. GENERAL
1.1. Introduction
This specification document describes the hardware of the new Electronic Control Unit (ECU) for Moto 3
class, starting from 2015 race season.
Dellorto introduced this new features to enhance data acquisition capabilities and allow eventual checks
about the ECU application, whereas needed.
DC-motor closed-loop control and knock sensor controls will be no longer available. Therefore, four
additional analog channel will become available. Two of the new four analog channels feature an higher
sampling frequency. Moreover, six analog channel are now available with 12bit resolution.
DoPE 2.0 external geometry, fixing points and connector will remain exactly the same of DoPE 1.0 for full
interchangeability. Regarding the I/O actually used for engine management, the existing connector pin
assignment still remain the same.
1.2. Operating Temperature Range
Within the operating temperature range, the proper working of the ECU is ensured. If the ECU goes out of
this range, malfunction may occur. This also includes the partial or complete malfunction of the electronic
unit.
The operating temperature is referred to the external metal housing, measuring near to the screws.
The operating temperature range is:
ECU ON: < 𝑇𝑤 𝑂𝑁 < 70
1.3. Operating vibration range
The operating vibration range with ECU ON is 20g peak from 20 to 400Hz
1.4. Degrees of protection
Protection grade IP67
DoPe Electrical Specification 7/34
2. MECHANICAL SPECIFICATIONS
2.1. General view
Dimension and fixing points are shown on the ECU drawing on Dellorto website.
2.2. Mass
The total mass of the ECU is about 430g
2.3. Installation
Keep at least 30mm from HT cable.
Elastic mounting according to the prescription is mandatory
Dellorto authorized fixing kit for ECU mounting is available
DoPe Electrical Specification 8/34
3. CONNECTOR
DOPE employs a Deutsch AS216-35PN military connector as external connection. The next table define the
general pinout of the ECU. Pin assignment is shown on the ECU drawing.

GEAR_USE_SENSOR parameter in DoPe. (See Engine Control Specification User guide for further information). (***) Auxiliary throttle position may be used or not. If it is used set the AUX_TPS_ENABLE parameter in DoPe. (See
Engine Control Specification User guide for further information).When the AUX_TPS_ENABLE parameter is set the channel is written with the corresponding “setup configuration (calibration)” regardless of the MARdata acquisition table linearization.

Nominal operating voltage: 8 𝑉 < 𝑉𝑏𝑎𝑡 < 16 𝑉
Nominal test voltage: 13,5 𝑉 ± 0,5𝑉
The operating direct battery voltage is measured at the ECU supply pin connectors.
The function of outputs, which are not required during the start operation, is guaranteed for Vbat > 8V.
Under voltage definition:
Learned data and error codes are stored in the non-volatile memory (Flash EPROM type).
If an under voltage condition occurs, only data up to dataT before the event are guaranteed.

A. CAN rx/tx DoRealTime management
A.1. CAN frame format
The DoPe ECU recognizes ONLY the standard CAN frame format 2.0A, it supports a length of 11 bits for the
identifier (Address): the ID of the CAN frames (in hexadecimal) that the user sets in the MAT table (received
in ECU or channel exporting) must be smaller than 0x7FF.
To log an information (channel) from CAN bus the basic information to provide in DoRealTime MAT table
editor is Address (frame ID) and Offset (bytes within the payload: 0, …, 7); when Bit count is not checked one
or two byte (selectable in Data type) are read from frame starting from Offset byte: raw information to be
linearized. When Bit count is checked a bit Offset, within the full 64 bit payload, must be provided following
next table. Bit count permits to choose how many bits will be read from frame payload.
When Bit count is checked, starting from 2019 ECU firmware, Little endian flag (Format tab) is managed by
the ECU. Previously firmware versions considers bit count management as big endian (Motorola) regardless
of above flag.
Starting from 2019 ECU firmware plus DoRealTime 4.05.19 the sign of raw CAN information (to log) is
selectable regardless of (linearization output) Data type.

A.2. Reserved CAN identifier
The following identifier number (ID) in the CAN frame that the user transmits, are not allowed:
0x061, 0x0CD, 0x0CE, 0x0CF, 0x0D0, 0X0D1, 0x0D2, 0x0D3, 0x0DA and 0x0DB -> Do not use (reserved
for new transponder x2 project)
0x0DC and 0X0DD -> Do not use (reserved if using transponder x2 project with virtual pit board system)
0x0F0, 0x0F1 and 0x0FA -> Do not use
0x0F2, 0x0F3, 0x0F4, 0x0F5, 0x0F6, 0x0F7, 0x0F8, 0x0F9 and 0x0FB -> Do not use if you have a Dellorto
Dashboard connected on the bike.
0x250, 0x251, 0x252 -> Do not use if you have the DoDash (COBO) connected on the bike.
The proper functioning of the CAN line is not guaranteed, and therefore of any device connected to it, if
you transmit a CAN Frame with one of these ID’s.

A.3. How to Export to CAN
In order to export a channel over CAN bus check the “Export to CAN” option. Different channels can share
the same frame.
- Address (Hex): the format of the CAN frame exported must be also standard. The maximum CAN
Frames (ID) to export in MAT is 20.
- Offset (Hex): byte offset in frame payload. Put 0 to write the channel from first byte of payload.
- Frequency: the maximum transmitting frequency is 100Hz. If you set a frequency greater than
100Hz, then this frequency will be saturated to 100Hz. If two or more channels are exported in
the same CAN frame (same Address) but the sampling frequency is different, it will be use the
greater sampling frequency.
- Bytes count: select if the channel fill one or two byte of frame payload. Normally is two; if one is
selected the LSB is transmitted. This is since 2019 ECU firmware plus DoRealTime 4.05.19;
previously versions consider two bytes.
- Engineering value: check to transmit after linearization value. Calling x the raw value, y the
linearized one (cfr Elaboration channel tab), n the decimal digit (Format tab), the byte/word over
CAN will be
y*10^n
When checkbox is unchecked: x will be transmitted.
