Lets see your V-500 data logs!...

[BRAAP]

Put close to 500 miles on my V-500 now, tuning little bits here and there, getting familiar with how to set it up, configure it etc. Car runs and drives pretty much as it did with OE ECU, only a couple areas a savvy driver would notice weren’t quite right yet. Using the OE O-2 sensor as my coarse AFR indicator right now, (LM-1 to be used later).

 

Things that make you go hmmm…..

The electronic filter setting for the internal map sensor as sent with the Direct Fit V-500 for the VG30DETT has an incredible amount of filtration, which is not what I would’ve expected for a relatively modern 6 cylinder. (This is installed in a N/A Z-32, bone stock VG30DE). I would’ve guessed it to have a smooth stable MAP signal. Apparently my guess was entirely incorrect. Wolfs suggested starting value for the MAP filter setting, when starting from scratch for most engines is 93.75%. As shipped to me, it is set at 37.50%, which is a LOT of filtering! In looking at my data logged MAP signal, I can understand why! The VG30DE does not have a smooth MAP signal at any RPM and/or load.

With the VG30DE/TT's twin plenums, I could understand if the MAP signal is pulled from one plenum, generating a pulsating MAP signal, but at the balance tube the joins both plenums? I originally used the balance tube for my MAP signal, then switched it to one of the plenums. No noticeable difference in the logs between either location, both produced the spiky MAP signal in the pics below regardless of location.

 

Here are 3 pics, one of the filter setting, the other 2 are a WOT run through 2nd gear tonight, one pic around the 3000 RPM mark and one at the top end of 7200 just prior to engaging the rev limiter. Oh, and the WOLF Rev Limiter is oh so butter smooth. Power just falls on its face softly, no bucking, surging, no popping, etc. WAY smoother than the later OE higher bit rate OZ-32 rev limiter.

Paul, a tip about screenshots. Hit your Prnt Scrn key with Wolf up. Open up MS Paint, Edit -> Paste and it will paste the screen shot.

 

This can be used for any desktop screen shot you want.

 

I don't use Wolf to datalog but rather my Innovate LMA-3 aux box. I log RPM, EGT, MAP, Meth Pressure, and IAT. My MAP and EGT signals are VERY smooth compared to what Wolf logs.

 

Unfortunately, all of my logs were on my work hard drive that crashed and may be unrecoverable. I'll post a screen shot of an older log I have on my personal desktop later tonight.

DOH!!!!

Uh…. Yeah….. I tend to forget how convenient that feature is. Using the family iMac for my “online” work really isn’t a good excuse for why I take the time to set up the camera and tri-pod for taking a picture of the screen when I could just “Screen shot”, “save as” in jpg, then use my jump drive and transfer the .jpg screen shot over to the iMac to post…

 

The fact that I’m not only using a Mac, but also publicly admitted to using a Mac might explain the lapse…

Yeah, I should port over to the Innovate datalogging with the LM-1 too. Innovates data logging is definitely more robust for "tuning".

guys, consider using this program

 

http://www.etrusoft.com/download.htm

 

it's called !Quick Screen Capture.

 

I have my F11 button set so that it triggers a selectable box area (or you can make it so that it triggers the entire screen capture), and it will automatically downsample to web-safe size and dump it into a folder of your choice, which I've called SCREENSHOTS on my desktop.

 

I then added a shortcut to the folder on my Quick Links toolbar, as well as a shortcut to http://xs.to that will both open up to 1/3 of the screen in different locations so I can quickly upload and host images.

Speaking about logging data has anyone been able import the log file into excel to very that what is being logged is correct?

 

For example when i log a start the delivered fuel and timing does not match what it should as set out in the map unless i misunderstand how starting fuel is calculated.

 

Same as at idle when i look at rpm, temp and other corrections to try and predict what the delivered fuel and timing should be it doesn't add up!

 

Plus mine doesn't even registed enrichment but clearly enrichment is delivered based on varying response of the engine when enrichment is altered.
