Anyone used DTA ecu's?

Hola,

 

i know my cars a soarer but the engines arnt all that different vvti and turbo :p

 

but just wondering if anyone with vvti has used any of the DTA fast ecu's?

 

my main tuner uses them a fair ammount setting up S2000's a 500bhp corsa, kit cars, pretty much anything really he swears by them,

 

but i'v never seen any on supra's or soarers just wondering if anyone on here might have one?

 

just want to know what they are like they have a ton of features but are they any good on toyota's?

 

cheers

An ecu is an ecu, some have more features and functions. some have more setting points. DTA have been around a long time, the owner of the company is an avid hillclimb competitor and ran a DTM Opel V6 engined Dallara with some success, running his own DTA ecu. They are (relatively) cheap, a lot of people use them, and there is an unofficial support forum at http://dtaforum.psycode.com/ Sadly I don't think there's

an official support forum, such as Motec have.

 

They are available with a mapping box that uses a knob to set timing and fuelling, with a button to press to load the settings into memory. I like that idea, but I am no mapper myself.

 

If you like wiring and sorting out none plug and play settings it may be an option, but I ALWAYS like to find a mapper and dyno operator and use whatever ECU they are happiest with and which has excellent support from the horse's mouth, the makers.

 

For those reasons I have always stuck to Motec and EFI Technology, but am going to try a Solaris or Life ecu at some point.

 

You need to ask on the forum, or ring DTA themselves and see if they will read all the Supra sensors without any hassles. I asked about a DTA reading Nissan optical cam and crank position sensor, but never got a reply. A similar question on the Motec forum would have a rapid response from a Motec employee, without doubt. How important a good support forum is varies from user to user. To me it's a vital asset.

ah awsome cheers for the info, the guy i use up here as i say he loves the DTA so i'll probably go with that plus i can get the S80 pro for £600 and i get discount on mapping (mates rates rock lol)

 

i was originally thinking motec as he can map them as well but there a bit out of my price range unfortunatly.

 

again thanks for the info thats all i needed :)

just ordered my DTA S80 list of features below :) for anyone that is interested. (only problem now is i need to order my new injectors/fuel rail/fpr/fuel pump/ custom make exhaust manifold/new bearings in the T04R lol ahhh its going to be a good year and i hope to have all this done before suprapod :p

 

 

 

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.

 

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.

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).

 

Firmware

 

The ECU firmware is flash upgradeable via the serial port with a special cable and software. Current firmware and software published on http://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.

 

Other Features
