hi,
I'm trying to tune my ve table using hp tuners, but my afr error histogram doesn't want to populate.
I have hp tuners standard, and I'm recording my wideband voltage through ac pressure. which shows afr in my table display, and I also made a custom afr error pid, which works and displays afr error in my table display.

I changed the standard afr error histogram in hp tuners to accept my custom pid instead of using the pre programmed pid. and I also added a filter to filter out commanded afr less than 14to 1 afr

any idea why my afr error histogram won't populate with values?

All the sensors or pid that are in the function have to be in the table also for the histogram to work u prolly forgot the commanded afr in the table. Add that and see if it works

I already had afr error in my table, and it's working in my table. just not recording in my histogram

u miss understood me you need the COMMANDED AFR in ur table also seeing how that is what [SENS.121] is in the function for the the AFR ERROR. Like I said every sen or pid that's in the function formula must be on the table

Here's a screen shot of my table wideband2 is my custom wideband PID, egr postion becuz I log through the egr so have to have that for wideband PID to work, where I'm pointing is COMMANDED AFR which u have to log for the AFR ERROR to work.

If u insert the Commanded afr into the table id almost guarantee will start working

This is what I have in my table for it to work I don't know is the low res on makes it work also or not, it should tho just uses less bytes

Drj8787

Post ur config file and custom histos or screen shots of them, the table and the function formulas for ur custom PID. If what I sugguested didn't help

Drj8787

Get it working?

mikesimpalass

still not working,
here is a screenshot of my table and custom histogram.

and I am actually using low res commanded afr, maybe I should switch to high res? thanks for your help

mikesimpalass

is there something wrong with my filter string? I removed it and everything seems to be working now.

You were filtering everything greater than 14.
