VE Calculator Software?
What's everyone using for a VE calculator? There's one I found online that works ok. AESwave sells one but it has to be mailed out on DVD. My laptop doesn't have one of those just like it doesn't have an 8-track player.
Hey Mike! I'm so excited to post my first reply and that it can actually help you. ATG has a VE calculator App for the phones. Just check your app store for “ATG Calculator” and it should pop up. It's free, effective and easy to use. Hope this helps, Andrew
Hey Andrew, I've got that same app by ATG on my phone as well. So easy to download on your phone and less equipment to deal with especially on test drives. Louis N.
Andrew, Thanks for mentioning our calculator. It's available for Android, but is not currently in the Apple store. On my iPhone, I use the online version through Safari at atgtraining.com/ve-calculator. I even have a shortcut, so it works just like an App. I hope this helps iPhone users. Thanks, Tim
Tim, I just did a calculation off of a freeze frame I was dealing with earlier this week (cruise) and yours calculated VE at 29.31% with theoretical load of 26.19% (In reality, yours could not calculate anything because it was a speed density vehicle with no MAF gps data, I calculated that number and input it into your on line calculator). Actual VE was 31.8% and the calculated load PID was…
Hi Randy, We sublet the calculations and haven't been able to have any of these kinds of discussions with the developer. All we heard was that is was Ford-ish, but the load calculation was always close to the available PID, so we never questioned it. Also, I know our VE is only useful at WOT, so I never bothered to check the load calculation under any other conditions. For other conditions, we…
Randy, the “theoretical load” implemented by this webpage is very simple: cylAir = maf * 120 / (rpm * cylinder); refCylAir = engineSize * 1.168 / cylinder; load = (cylAir / refCylAir) * 100; var per_t_load = parseFloat(load) > 100 ? 100 : parseFloat(load); $lbl_atg_t_load.closest('div.skillbar').attr('data-percent', per_t_load + "%"); P.S. At…
Thanks. I see it now, that's absolute load. I hate when they don't tell us which load they are computing.:) Enter 100 for BARO and 25 C for temperature (should be ambient not intake anyway) and theoretical matches VE. The theoretical load is off from the actual PID and my calculations because I uses the same constant 1.184 which is from SAE for ABS_LOAD. BTW, I made an error in my previous post…

Hello Mike, I use the OTC web-based VE calculator: otctools.com/ve — Dave
Use the generic PID absolute load. It is VE for sea level and ambient of 25C. For my altitude, 5000 feet, I have a 20% correction so I just add 20%. It's far more accurate than those calculators. FWIW, I wrote my own that does a lot more than what those on lines ones do but for just VE, absolute load.
I like to use a VE calculator to compare to what the PID says.
MAF VE calculator - Microsoft Store Apps There is another free one
Hello Mike, the Escan from ATS works fantastically, I used to do my own calculation, but after I got the Escan, I do it faster and efficient
Agreed, the ATS EScan is awesome because it gives you useful VE data under all operating conditions. Ours is just a WOT calculator for people without an EScan.
LoL dont get Randy started on the ATS version of the VE calculations!!
What is the tool worth, roughly? If you don't mind me asking?
I've used the atg, works great. If you're looking for software, I've used Escan, works very well. It's a little pricey, but it does VE tests well, and catalyst efficiency so you can actually see the numbers.
I have the atg one on a tablet and it works well, but I use the one on my laptop more often that Steven Mcgrew built. its a bit more iin depth than the atg calculator and just as easy to use and there is a database for known good for a lot of models. It’s a free download and he also has a pressure waveform overlay he built that’s free as well that I use a lot. To get more in depth in ve testing…
