So, you have PID set-up to convert your voltage coming through your AC sensor line currently and it's working?

Then your % error function is:

100*([USER.What ever yours is]-[SENS.121])/[SENS.121]

... or is that not the histo you need?..lol

1- Dont delete the " <> " in the strings function just insert the custom pid's in there " otherwise you will get an unknown parameter error sometimes and you'll have a wtf face on lol !

2- Make sure you add " AC Pressure " to your pid list then create the custom pid and insert it


once ur pid is dialed in perfectly, open up the the histogram called MAF AFR Error Or VE AFR Error & change the sensors or pids to the custom ones you created !

hey np man...when you to post a reply, just choose advanced and there's a button called manage attachements, click on that and try to upload, if it didnt accept it just " compress the files into a zip files then attach, " an alternative would be uploading the files to file hosting service and sharing the links on here...
