DTA S40 Pro ECU *Ignition Only*

Maintaining the highest manufacturing quality and reliability of more sophisticated ECU’s in the S series range it provides a lower priced solution for a wide range of applications.

The primary aim of the S40 is to provide an economic ECU for relatively simple wasted spark four cylinder engines using semi-sequential injection.

Advanced features and system flexibility, however, are in no way sacrificed to this aim.

ECU Functions


Engine Configuration

20,000 rpm capability
Flexible and easily adapted to different OEM, crank, cam sensor arrangements.
Genuine four and two stroke support.
wasted spark or distributor.
User controlled fan activation.
Sensors can be calibrated individually with a lot of preset options supplied.
Flexible Tacho Output
soft and hard rev limits 

Main Ignition Functions

Air, coolant and manifold pressure compensation maps.
RPM and load breakpoints can be calibrated by the user.
Throttle or MAP as load.
All maps with one or two dimensional with interpolation as required.

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.
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.

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.

Full Throttle Gear Shift Cut

Shift cut capability with 1ms resolution, variable for each gear with 
full switch de-bounce capability.
