The S7+ cannot directly drive a DI injector. So it would either need an ecu capable of doing it directly, or a regular ecu with the GDI driver box ( ie, the GDI12 ). I do not believe Syvecs has an ecu with direct capability of more than 4 cyls at this time
Whilst it might be possible.....it would take extensive CAN knowledge and ability to reprogram your Haltech to be able to use it. So in reality, No. The X10 or X20 expander would not be usable with a Haltech ecu
