现时国内Subaru车主如果想改装ECU(行车电脑)来提升车子的性能，唯一的方法是加装外挂式电脑和使用由国外专家根据外地的Subaru规格和行车环境而编写的软件。但安装复杂的外挂式电脑很容易会因设计、接线和与原装传感器不配合等问题而令效果欠佳。另一方面，在国外开发的软件亦因两地不同天气、油品或是不同发动机规格等问题而不能完全配合国内情况，而且一般外加的软件很难完美地配合原厂电脑工作，结果会引发原装电脑产生错误码甚至使到原装程序里的一些保护机能失效，令车子在特殊情况下(如汽油辛烷值过低，点火不正常，涡轮超压等)不会行使自我保护模式而对发动机造成严重损害。
针对上述情形和出于对Subaru车系的钟爱，华龙赛车特别从英国引进可以把原厂电脑升级为可程序电脑的Ecutek软件系统，并利用全国唯一的DynoDynamic 四驱测功机专门为Subaru编写了一套完全适应中国国情的高性能程序。在Ecutek系统的帮助下,改装Subaru的行车电脑时完全不用装拆任何东西，只须透过原厂电脑检测插座(OBD II)便可直接改写程序，加上华龙赛车的专业编程技术令车子不需经任何重大改装便可大幅提升马力，效果优于绝大部份的市售改装电脑。用原装电脑改装除了可减低成本和简化工序外，更可保留原厂的保护机能设计，在提升车子性能之余更同时兼顾安全及耐用性。此外，改装后的行车电脑依然能和Subaru的原厂诊断电脑100%兼容，而且无法查出内部程序是否有变更过，因此不会影车主与原厂的关系。
China Dragon Racing Development (
CDRD) is proud to present the product that you Subaru WRX owners have been waiting for – remapping of the standard ECU using the Ecutek software developed in England. You no longer need to purchase separate piggy back units and boost controller. Ecutek can do all these plus much much more. There is no wire to cut and no soldering of chips. Everything is done via the standard diagnostic port (OBD II).
Ecutek 系统的优点：
Other advantages of using the Ecutek system：
1 .调整供油量及点火正时至理想设定(adjustment of fuel delivery and ignition timing to optimal setting)
2 . 精确地控制不同工况下的涡轮增压(accurate control of turbo boost level under various conditions)
3. 延后/解除车速限制(adjustment of vehicle speed linit )
4. 延后/解除发动机断油限制(adjustment of engine rpm limit )
5. 重新校准转换大号喷油嘴后的供油量(correct recalibration of fuel delivery after changing to larger injectors )
6. 保留原厂安全和自我检测功能并能正常工作(factory safety and self-check functions are retained and fully functional )
7. 配合Subaru原厂诊断系统工作；Subaru 4S店的技师在进行正常维修工序将不会察觉行车电脑已被改编。(factory diagnostic system compliant ; Subaru dealers will have no problem servicing Ecutek tuned cars )
8. 兼容两套不同的程序 -节油 /动力模式选择(只限某些ECU型号)(switchable maps (for some ECU versions only) – one map for economy and one for performance )
9. 在加配Detadash后可容许车主自行调教行车电脑的设定(只限某些ECU型号)(user tunable (for some ECU versions only), will require Deltadash)
我们设计了多阶段的改装套餐，并配置相应的软件来供客户多样化的选择：
We are now offering different stages of tune and each comes with a matching software by using Ecutek：
Stage 1 电脑调教 + Pipercross风格 + 后段排气管
Stage 2 电脑调教 + 60 mm 全段排气管 (不包含排气岐管)
Stage 3 电脑调教 + Stage 2 + 顶置式中冷器
Stage 4 电脑调教 + Stage 3 + 中冷器喷水冷却系统
Of course, we are not stopping at Stage 5
The range will certainly grow in the future. We will continue to bring you more powerful packages. Bigger turbos are already in the pipeline.
Other Ecutek products for Subaru : Deltadash -Allows monitor and datalogging of all ECU data through the use of a laptop computer, -Accepts external sensors – such as wide band lambda sensor and EGT sensor, -Check and erase factory ECU fault codes, Dash Top Monitor
ECUTEK凭借着与原装电脑100%兼容，充分提升性能，不需改动或增加任何硬件，保持原车完整性，不影响到日后检测和保养，保留原车保护功能，自由改动升级等特点，为改装车提供了性能提高、机能保护、日后维护的宽容兼顾性。连专门开发SUBARU WRC厂车的 PRODRIVE在限量市售车及市售改装电脑上也运用了Ecutek系统，Ecutek无疑成为了改装SUBARU电脑的佼佼者。
