Do I need to use whatever sensor went here? It’s a 74mm tb and it’s going on my 8. I think it’s meant to have a different sensor to what the 8 uses but what I’m building is in no way a stock evo it’s fully built so just wondering if this is needed or can be blanked off somehow?

 

There is an adaptor to put the OEM ISC motor there, you should buy it and install it so you maintain idle control with the ECU.

It's pictured here, you may need to call S90 directly to get it if you don't have it-
