Playing around my PC3 today the pressure input uses a 0-5v input and you can use it to with any 0-5v output i:e a wideband unit. The install manual give you a conversion chart V to A/F reading so wired in my innovate MTX-l into the pressure input wire to use the LCD100 to log readings, input Voltage marries upto display so it works. With the PC3 you can set the pressure input to increase or decrease the fuel map based on voltage. It is suppose to be used to increase fuel as the boost rises so question is.
1. Has anyone used this feature like a fail safe or auto tune i:e if the A/F ratio starts to get lean ( just using a random reading) 1.8125v or 12.9A/F trigger it to add 1% fuel to pull it back a little the leaner the reading the more fuel to add.
2. If it can be set correctly can it be used to compensate for Nitrous?
I know the best thing is to get a map tune and I am booked in but I like to play and try new things see what I can make happen
