Histogram works.... once.

[Bayer-Z28]

So I have a histogram that I set up to read my wideband that I am back feeding through the AC pressure sensor. I have a new MPVI2 interface on the way.

But the histogram to tune VE tables works once. If I disconnect and adjust the tune and come back it doesn’t work. Nothing moves it’s not showing its reading anything. I’ll try to upload the pictures to see if someone can help me figure out what’s wrong.

And I’m getting seriously frustrated with hpt lately. This h/c tune for my c5z has fought me every step of the way.
This is weird. I’m logged in on my pad, but can’t upload pictures. Can’t log in on my laptop because it says my pw is wrong. Or I've used my quota....but I’m on here (phone)... on the same network.

Here’s the pictures.

Had to host them because they won’t upload.

Got it… math was off. Brackets and parentheses was wrong. And the histogram MAP was set to read in PSI instead of kPa. Messed w it some more today and figured it out. And it’s been working when I need it thankfully.

Figured I’d give an update. And for the sake of people searching, I was tuning VE so the MAF was set to fail and it was putting me in reduced power on my C5 and shutting me off. So I just set the SES to “no error reported” and it’s finally not shutting me off. For a while even tho the MIL was off and set to “no error reported” it was still putting me in reduced power mode.

So I finally able to get this dialed in.
I haven’t done this in over 10 years so I’m having to relearn everything.
