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.
Flexible Input/Output
Three uncommitted input tables which use 0 - 5 volt inputs or any input the S40 knows already, linked to fuel and advance modifiers and a PWM output.
Voltage Compensation Tables
User configurable voltage compensation tables for coil on time (dwell time).
Diagnostics and Test Features
Full sensor diagnostics and fault recording.
Extensive engine run time recording at different load and speed conditions.
Ability to exercise coils without engine running for fault finding.
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.
