S60 PRO Overview

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

Designed to meet the demands of the latest generation of very high revving, four coil, sequentially injected engines, the S60 PRO is the our latest ECU.

Aimed primarily at the advanced four cylinder market, the S60 PRO also caters for wasted spark non-sequentially injected engines of up to eight cylinders.

 
   
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.
Twin spark engines.
Twin injector engines.
Sequential or grouped injection.
Individual coils, wasted spark or distributor.
Unequal coil firing capability.
Unequal injection angle capability.
Delayed sequential injection.
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 Fuel and Ignition Functions

Two main fuel, spark and turbo maps selected by a dashboard switch.
Comprehensive start up fuelling options both time and temperature dependant.
Air, coolant and manifold pressure compensation maps.
Throttle transient increase compensation.
Throttle transient reduction compensation.
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.

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 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.

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.

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 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 nine 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.
