So, in an effort to be a little more helpful than a link to a 58 page discussion on just the LWTS in general (though very helpful if you have time to read it and can put up with the occasional "shiny object" diversion), you can find a good place to start on page 17
. Portcity mentions he uses the gm 1 bar map equation for the sensors that redline 6 summarizes on page 34 in post 334
. Based on that sender, I wrote a custom equation that I have to try as I am now waiting on the analog cable to arrive before I can start playing with it. It's on page 57 in post 563
. Hope this answers your question a little better. And if you already took the time to read through everything in the link portcity posted (which you should anyway at some point), hopefully it'll speed things up for someone else that stumbles across your post!
