2312 GMVE Not Avail, Alternative Math?

[str8dum1]

On my 2018 Silverado, parameter 2312 just gives me 0's.

We know that GMVE is mg fuel flow * manifold temp / MAP

So if I use (([2394.71]*[2126.240])/[50030.91]), that should replace the 2312 value, correct?
2394 - instant fuel flow (g/s)
2126 - Manifold temp (k)
50030 - MAP (kpa)

Then its just a matter of find/replace 2312 with the above equation.

from this: (([16.71]*(1+(.01*[6.156]+.01*[8.156])/2)-[12.56]/60*4*[11.92]*[2312]/[2127.240])/([12.56]/60*4*[11.92]*[2312]/[2127.240]))*100

to this:
(([16.71]*(1+(.01*[6.156]+.01*[8.156])/2)-[12.56]/60*4*[50030.91]*(([2394.71]*[2126.240])/[50030.91])/[2126.240])/([12.56]/60*4*[50030.91]*(([2394.71]*[2126.240])/[50030.91])/[2126.240]))*100

Anyone have luck making a math for GMVE when it is not logging? My histogram gives me -80 for almost the entire table and I know my VVE table is within 7% when I tune VVE only.

Thanks!

software version issue? My 2017 Silverado gives me good data for 2312

Might be close, but you will be basing your %error on a calculated GMVE value and not the actual value looked up from the VE table. You should contact support and see if they can get the channel to report correctly.

Hello, I don't have this PID 2312 either. Did this math work for you? I am tuning a v6 engine and don't think this PID exists at all. It is for a Chevy Colorado 3.6L. Any help or direction will be greatly appreciated!

Hey there! It sounds like you're having some trouble with your 2018 Silverado and trying to replace the value for parameter 2312.
Based on the equation you provided for GMVE, it seems like you're on the right track with trying to replace the 2312 value with a calculated value based on other parameters. If you substitute the values you mentioned into the equation, you should be able to calculate the GMVE value for your truck.
As for your question about making a math for GMVE when it is not logging, it's difficult to provide a specific answer without more information about your situation. However, it's worth noting that the GMVE value can be affected by a number of factors, including engine load, air/fuel ratio, and more. If you're having trouble with the GMVE value, it may be helpful to consult with a mechanic or tuner who has experience working with your particular vehicle to diagnose and resolve the issue.
I hope this helps, and best of luck with your truck!

That is a bunch of words that are, technically, relevant to the topic, but in real terms add exactly no real information. You are simply repeating key phrases already used by others in the thread to pad out your word count. I predict an edit in approximately 3 days to add a link to an essay-writing service.

Pretty sure kingtalon will take offense to this.
