Boost issue in graph with hp tuners 3

[Tom Waldner]

I think I have most of my issues figured out moving to new software, but one I cant seem to be able to, No matter what I do, the scanner will not read past 22.99 Psi boost on the graph. I tried the boost pid they have built in now, I tried making my own, always the same 22.99 psi and wont go any higher. I'm boosting to 28 and it just stops at 22.99 on scanner. what the issue? Also my knock retard graph is not populating the squares, it was earlier, but it stopped for some reason, I'm using an old log file, will log a new file tomorrow see if it works. but the boost think does not work .

post your log and your layout.

I need your Channels file, and your tune file.

[Tom Waldner]

Channels file? Where do I find that?

[Tom Waldner]

I uploaded the tune, its in the link above, but still don't know what u mean by channel file

[Tom Waldner]

oh never mind I figured it out. lol dumb

[Keith@HPTuners]

In the Channels display on VCM Scanner, click the save icon.

ok I figured it out, I made my own formula and was accidently putting lowres boost in psi and baro in kpa, I put both in psi, now its right thanks anyway

There is a built in boost math parameter that works well. I would try to use that one.

it doesn't give the correct boost, it only reads 22.99 psi when I'm at 28 psi. the issue with that built in one is it uses intake manifold absolute pressure reference instead of boost low res. boost low res is lower map sensor and gives the correct boost reading when made into a formula boost lowres - baro

I'd have to see a log with MAP and baro logged to understand it better. I'm not running anything with 28psi yet
