The SDI ECU is the perfect solution for integrated direct injection engine management. Based on the highly popular S8 architecture the SDI just has less inputs and outputs for those GDI applications that don’t require the complexity of the full S8.

UP TO 8 CYLINDERS/4-ROTOR ENGINES MAX

Maintaining the highest manufacturing quality and reliability of more sophisticated ECUs in the S series range it provides a lower priced solution for a wide range of applications.


 
The primary aim of the S40i is to provide an economic ECU for relatively simple wasted spark four cylinder engines using carburetor fueling systems.


 
Advanced features and system flexibility, however, are in no way sacrificed to this aim.

The S8 ECU is our most popular unit offering 24 x Inputs, 28 x Outputs, 2 x Lambda Inputs, 2 x Knock Inputs, 2 x EGT Inputs and 2 x DBW Drivers. All software features are enabled from factory except for Direct Injection Control and Paddle-shift Control which is an optional upgrade.

UP TO 4 CYLINDERS / 2 ROTOR MAX / NA6-NA8 PLUG-IN MIATA / LOOMS, CONNECTORS SOLD SEPARATELY

Maintaining the highest manufacturing quality and reliability of more sophisticated ECUs in the S series range it provides a lower priced solution for a wide range of applications.


 
The primary aim of the S40 is to provide an economic ECU for relatively simple wasted spark four cylinder engines using semi-sequential injection.


 
Advanced features and system flexibility, however, are in no way sacrificed to this aim.

Over half a century ago DENSO began designing and supplying to OEMs. Since 1972, aftermarket products created exclusively by DENSO have been available for Domestic, European and Import vehicles. Since the beginning, DENSO has consistently provided distributors with products featuring wide coverage across makes and models, quick and easy installation the first time for technicians, and product reliability and longevity for consumers. 
The quality of DENSO parts is guaranteed because every component that leaves a DENSO factory has been designed with precision, manufactured to the strictest OE standards or above, and subjected to rigorous safety and performance tests. In the end, it all comes down to quality - that's what the DENSO name stands for.
