Open or closed loop turbo pressure
control via PWM valve.
Modify target turbo pressure by
gear selected.
Modify target turbo pressure by
vehicle speed.
Two control maps selected by switch
on dashboard.
Active base PWM map for easy
calibration.
Idle Control Functions
Open or closed loop idle
speed control via PWM valve.
Closed loop idle target
speed temperature dependant.
Active base PWM map for easy
calibration.
Fuel enrichment table
calibrated versus PWM percentage
ALS Control Functions
Full ALS ignition and fuel
maps
ALS valve control together
with map switching controlled by dash board switch.
Cam Control Functions
Open or closed loop cam advance control via PWM valve.
Static offset table to zero out electrical movement
effects.
Active Cam Target Advance map, load and speed dependant.
Active base PWM map for easy calibration.
VTEC Control
Water Injection
When not being used to
control the camshaft, cam base PWM map can be used instead for
water injection, giving complete load and speed dependence.
Flexible Input/Output
Three uncommitted input
tables which use 0 5 volt inputs or any input the S80 knows
already, linked to fuel and advance modifiers and a PWM output.
Launch Control
Fully flexible first gear
launch capability.
Extensively tunable to
individual vehicles.
Traction Control
Fully adjustable from the
dashboard.
Measured from all 4 wheels
Full Throttle Gear Shift Cut
Shift cut capability with
1ms resolution, variable for each gear with full switch
de-bounce capability.
Voltage Compensation Tables
User configurable voltage compensation tables for
injector dead time and coil on time (dwell time).
Firmware
The ECU firmware is flash upgradeable via the serial
port with a special cable and software. Current firmware and
software published on
www.dtafast.co.uk.
CAN PC Communications
The ECU can communicate with
the PC via DTA's USB -> CAN converter. This solves the problem
of unreliable USB -> RS232 converters.
Data
Logging
Up to thirty six separate
items can be logged.
Three user selectable logging frequencies.
Up to 16 hours logging capability.
Graphing can be done on-line to the ecu.
Diagnostics and Test Features
Full sensor diagnostics and
fault recording.
Extensive engine run time recording at different load
and speed conditions.
Ability to exercise injectors and coils without engine
running for fault finding.
