Calc.VET: correcting MAF and calculating VE (in single log)

[Whipped383]

Thanks Joe I'm still working on setting it up. Iv read through it several times and taking my time.

No worries, take your time

Got my VALC_VE all setup and took a log. Let me say for anyone thats never done it this way it is so much easier than AUTO_VE and AUTO_MAF seperatly and saves alot of time . The proof is in the pudding with before and after fuel trim shots. My MAF Was off a long ways, My VE not so much but it was off some. Heres some screen shots of my fuel trims


Before


And After.

Should I do it again or do you think thats close enough?

I just did this on my 8.1 and loved the results. My question is on my other truck (see Sig) I am running boost and a COS3. Do I just make sure the OS listed in the first post matches my original OS#? Then just add the over 105KPA tables to the chart? Or will it not work for me at all?

When I made a custom os for the whipple 8.1 I messed with the custom os makes an addition be table from 105kpa - like 300 or something. And I'm guessing for the vet tuning you would have to make a new map for that spot or possibly add rows or columns to the vet map currently and expand the kpa values but not positive

That is quite good, further iterations won't get closer.

Good job

Yes (OS matches). Correct (Boost VE table simply extends Main VE table).

You can go either way, two maps, or a single large map... the single map is easier to work with.

Trying to get the maps to display the right information, and I'm doing something wrong. A short log and calc_pids are attached below. The values that are being calculated seem wrong. I cannot get the g*K/KPA to either display or calculate correctly in the scan tool. When I added in displacement, the % percentages seemed way to low. I'm primarily looking at the 50 kpa and 800 rpm cell. I know I will need to significant logging, just want to make sure my PID selection and calc_pids are configured correctly. Comparing the LFTBEN to calculated VE do not match either. 10% based on LFTBEN and almost 50% on calculated VE, BEN corrected.

Any ideas what I might be doing wrong?
