    the car i am building now has the FIAV and ISC removed. can i feed something else into the ISC input and use it for logging? a fuel pressure sensor would be the bees knees. does link have an ability to swap that sensor? i have link v3 for this built but the motor is still next to the car.

    i know the EGR input can be used but i want to run a boost sensor on it, and a wideband in narrow sim mode. the 1g does not have a ton of other options.

    ISC pins on ECU are not sensor inputs, they drive the ISC stepper motor coils. The ECU just hopes it complies and doesn't blow the drivers due to short.

    You can connect the boost sensor and fuel pressure senor to the same ecu pin but you need to disconnect the plug of one sensor while the other one is connected and of course change the pin settings in ecmlink accordingly.

    Good idea. Natural thought that extends to this is a SPDT switch in the cabin so you can do it on the fly, at least in terms of sensor itself, but just watch for voltage drop as any will affect sensor readings. Anything less than 5mV I wouldn't be overly concerned about.

    Hell yeah, an even better idea. I'm actually undergoing this project as we spoke. So happy you recommended that.

    i wonder if the isc stepper could be set up to control a mivec butterfly...
    or maybe a NOS trigger? seems like a waste to just abandon it.

    What MIVEC butterfly?

    Anything that falls within the operating parameters of the drivers could potentially be used but only if the ECU code is sending the correct voltage signal at the correct time.

    Single pole dual throw switch.

    It has three terminals which allows you to complete a circuit one of two ways depending on if the switch is in the up or down position
