I want to log my fuel voltage under boost and my understanding there isn't a way to log it but wanted to check. My next thought is tapping into the wire and running it in cabin to a volt meter.

anybody?

I wonder if you could run a line right into one of the inputs on the tuner. I would first check the voltage with a multimeter, but theoretically you could log it with a custom input right?

^ I have no clue how we are going to do it is tap into the line and run it in cabin with a mutimeter. I don't have it it's a friends that was going to bring it over to log my car. I have searched and I havent seen a yes or a no. I emailed efi to see what they say. He's unsure also he thought we could but is not sure

I'd be curious what the span of volts that may be seen. Considering a wideband usually reads from 0-5 volts, if you hook up a multimeter to this and can identify the high/low output you should be able to get a sense for what an input on a tuner would see.

Where is a GM engineer when you need one??
