DTAfast

DTAFAST – ADE TUNING ARE APPROVED SUPPLIERS AND FITTERS

 

DTAfast designs and manufactures engine management systems for spark ignition engines intended for use in competition vehicles. All their systems are easily mapped and are very competitively priced. The systems are designed to be fitted to almost any engine. Usually on a modern engine the existing crankshaft and other sensors can be reused. If this is not the case then they will provide a full range of temperature sensors, crankshaft sensors and wheels, pressure sensors etc. Their systems are in constant use worldwide and countless competition successes have been recorded from club to professional motorsport, including motorcycling, jet ski and snowmobile racing. A number of multi-national motor manufacturers use the systems for longevity testing of their engine components because of their transparent ease of use and their ability to stress an engine outside its normal operating envelope.

 

DTA S60 PRO

 

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  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.

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.
