DTAfast S80Pro ECU

Stunning performance and complete environmental protection combined with a truly impressive and expanding range of features


The S80 and S100 ECUs represent the top of the range, differing only in the number of individual coils and sequential injectors they can handle.


Comprehensive input and output features are provided allowing sophisticated 6, 8 , 10 and 12 cylinder engines to be controlled easily and successfully.


An extremely high level of environmental protection has been implemented in its design allowing safe use in extreme conditions such as grass track, off road, marine and motorcycles.

Paddle Shifting Function

Full closed loop paddle shifter built in

Supports most sequential gearboxes, including half step shifts

Auto upshift, throttle blip on downshift

Configurable retry strategy


Lambda Control Functions

Extensive lambda parameters table to ensure stable closed loop operation and emissions requirements can be met where needed.

Full three-dimensional lambda target map.

Auto-tuning function.


Turbo Control Functions

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 dependent.

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 dependent.

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 S60 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).



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 our 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.
