Syvecs S7i Stand Alone ECU

£2,200.00 (+VAT)

The Syvecs S7i engine management system has been designed to cater for clients on a budget that still need a extremely powerful controller!

Replacing the S6i, this new ECU can be purchased as a stand alone unit or as part of the Syvecs Plug N Play kits.

All software features are enabled from factory except for Direct Injection Control and Paddle-shift Control which is an optional upgrade.


The Syvecs S7i ECU offers an extremely high level of precise engine management control for the clients on a budget. Featuring a triple processor unit uses a high speed RISC processor for code execution and an additional large FPGA for high speed engine position tracking. This allows the scheduling of code to be independent of signal patterns, increasing flexibility, efficiency and accuracy under transient conditions. The powerful combination also allows advanced control algorithms but yet easy to map for the end user still using our SCal software and S7 Firmware.

Designed to cater for PnP kits where clients also need the programmable CAN Bus and Drive-By-Wire support offered by the Syvecs S7i.

Using the same 3 x AMP Superseal connectors, the Syvecs S7-i also has the same pinout for its I/O as the S7-plus ECU. This feature enables the user to easily upgrade to an S7-Plus at a later date if more inputs and outputs are needed without having to change the loom.

In addition, the Syvecs S7i is cased in a sealed aluminium billet unit and comes with 3 x waterproof connectors offering 94 pins.
