Hello at the moment i switch my 2nd gen 3sgte to a 3rd gen ecu.
But i whant to keep my TVIS System but the gen3 ecu dosent suport it, so my plan is to handle it with an VAFC that reads RPM and Manifold Pressure and with that information i will use the Vtec option from the VAFC to controll my TVIS. Does anyone already do this and know what i need? Relays oder some other things?
And what Voltage controll the TVIS Vsv 5V or 12V? And is it triggered with Positiv or Negativ Voltage?
Same question with the VAFC, does Vtec controlled by 5 oder 12v an negativ or positiv voltage?
If i know that i can selfmade a relay controler if its different.
The other thing is, on what RPM does the TVIS open and when does it close?
What do you guys think? Is it possible with an VAFC? Or do i need another thing to controll TVIS?
