I am trying to tune VE by wideband. I do not have the EIO cable for hpt2.0 so i made a pid using the egr position input. It reads fine in the table or the histogram. How do I now get a histogram to show Air/fuel ratio error? my custom PID for the dynojet wideband is [PID.21811]/.626=10 that corresponds exactly to my gauge.

i tried the one in hpt2 that was like 100*[{sens120]-[sens121]}-[sens121]

but i dont have a sens120 in my list which is prolly a wideband connected to the eio
thanks for any help!!!
