Figured it might be worth making another post here.

http://dl.dropbox.com/u/27624835/car/ec ... 20work.xls

This spreadsheet aids in calculation VE from MAF and back based on 3D MAP/RPM tables.

I.e. it allows you to pop in your MAF flow and see VE, or pop in VE and see MAF flow. It also can display engine load.

It was primarily used to build speed density code and initial mappings, but it might be of interest to people to play with.

I still can't download from that link. A dialoog box pops up asking me to open it or save. Opening it gives me a blank webpage. Saving it comes up with "internet explorer cannot open the website or it's unavailable".

Can you attach the file on here?

Cheers.

Just click the link, save the file to your PC, then open it with Excel. Very straight forward.

If you are having problems with IE, download and use Firefox ;)

Some of us are clearly having problems for whatever reason. The helpful thing to do would be to post the file on this thread so those of us having problems can download it. :|

It does seem that if you click on the link it wants to download as a Word document. But if you Right Click on the link and select Save As, then it will open in Excel properly. Just make sure the filename you use ends with the extension of xls

Yeah my host has some sort of bug that makes it detect as a Word doc. Save and rename to .XLS and it should work fine.

Yes, I need this spread sheet too, I need it to calculate VE to be able to tune AVCS. I can make my own spread sheet based on Freon's formula, but I'm not sure about two inputs, boost, is it suppose to be in Bar or PSI? And 'sea level pressure' what format would be such number? Freon used format like 14.35 for sea level pressure while if I check for the 'sea level pressure' in my area online I get a numbers like 1016.03.

I'd appreciate any feedback or uploading Freon's original sheet here

I have one based off of how the group n rom converts psia into grams of air, so it's really only good for ej20 variants as far as I know. Still want it?

I use this along with an interpolation spreadsheet and convert g/rev tables to how they would function on my engine (with it's VE table) as if it were actually using the g/rev table.

I use 14.5038 PSI (or 100kPa) as average for sea level, but where I am currently it is actually 1020-1030 mb or rather 102-103kPa.

File says original creator was Brian Check, bcheck555. I added something to it.

I downloaded your sheet, but I'm not sure what inputs are you using, can you elaborate further? please also upload the interpolation sheet, as I mentioned I want to be able to calculate VE through my data logs to be able to optimize AVCS advance.
