as long as you're not interested in receiving assistance, I suppose so ...

How does the way I read my data at home have to do with whether I want assistance or not. I just take data in faster when I read a graph over a chart. Obviously I don't get raw data from it, but you can't read every cell in a log at the same time either. Don't tell me you would actually read through 200-300 plus rows of AFR numbers if not more to look for AFR spikes. In my opinion, its a million times faster to see the spike in a graph and go directly to that spot in the spreadsheet. It is the way I prefer to read my logs at a glance and when I first open them, everyone is different. Imagine ATR with no data visualization whatsoever, no graphs, no color coding the spreadsheet cells. Imagine how difficult it would be to read every single cell in every single chart to find a rogue input you made to a tune, when you can just take a split second per tab to notice a spike or a small bump in the 2D/3D graph. I just choose to use data visualization to process info faster. If it is easier for you to read raw data, then kudos to you. From my point of view, your the one doing it the hard way lol.

Better?

Are you using the fancy AP USB with the 'multi-joint' bendy end on it?

I've encountered two of these that consistently give errors that ordinary USB's don't......

Just a thought.

Dude!
I'm getting an Office Violation Security alert trying to open that file.

Are you an 3773311 Haxor now too?

edit --- opened it

Sooooo afr's look pretty good imo, still a bit rich is some areas (Mid 13's) ... and you have 14.11 spike at 4000 rpm which isn't too bad but could use some fuel.

What concerns me is you never reached 100% load and your g/s should be in the 200 by the time you reach 8500 rpm

I remember from my 3rd gear WOT runs I could actually reach 103% Calc Load

It's been awhile since I looked at a 2nd gear WOT NA ... any chance you have enough snow off the roads to do a 3rd WOT

LOL ... seriously the snow is gone right? ahahahahahh ... ok ok .. really?

edit edit ---
Try to do only one thing on your log file... add the Throttle or Pedal Position as well to your log.
All that stuff before the WOT is rather .... well in the way

Yes, I work entirely from data logs and have no issue finding spikes etc. I have looked and found it before you have made a graph. If I am evaluating AFR I simply scroll down through that column after freezing the first row data header descriptions in place. Looking across the row gives me all the associated data for that point in a single glance; load, rpm, IAT, timing, etc. rather trying to piece it together in somebody elses graph scaled in an unfamiliar way. I do graph some items, but very specific and dedicated one on one data. People who put a half dozen or more variables on the same graph with altered scales to make it all fit just make a pointless picture that serves no real purpose. I have watched countless people here waste their efforts doing this for years ...

To Stealth, just using a normal gold plated usb I use for all my pc devices with that jack on it. I have tried 2-3 different ones though.

WCS, the security alert is probably caused by me using openoffice. My guess is the 4k spike is me probably going from CL to OL, I'll take a look at my tune and see if anything is amiss. I had the pedal to the floor at around 2500 RPM. Would switching from one of those shitty no name washboard style paper filters surrounded by plastic supports to a k&n filter knock my maf cal off? Before I changed it i always got 210-220 g/s wot, I checked my intake to see if it was sealed right from changing the filter and didn't see anything out of the ordinary.
3rd gear wot is hard around here. my bro got nailed with a ticket just recently doing the same thing I do. Its not worth it to me any more. 2nd wot is as high as I go around here, I have been ticket and pullover free for 8 years, I ain't changing that over a tune log. I can always do it on a incline to make the run longer. There is a km long 35-45 deg incline maybe 10-15 min from my place on the highway. Would probably double the data points doing it there.

Yes the snow was gone months ago. Sudbury isn't that far north haha. was 30+ with humidex yesterday. Got 4 24" fans circulating air in my house lol.

Yeah I could have cut up the log for ya. Traffic makes it hard to get just a run in there sometimes.

Team. I agree the graphs with one thing work better. The mashed up chart was simply experimenting, It does not work well for tuning, but I find it does come in handy once in a while, I can open the log, look at it to remember a specific issue and go there in the spread sheet and start looking at numbers, It jogs my memory faster then scrolling though the data. I'll have to look up how to freeze the headers, I'm sure you use office so the shortcuts you use most likely don't apply to me.

LOL I know I know just give'n the gears to a fellow Canadian eh.


I wouldn't think that just changing the filters would screw up a maf calibration. If it was just the filters and not an intake change.

Yeah that low g/s is concerning ... I would focus on that personally.

Team?
Stealth?

Any input on the g/s deal?

TechnoPsycho87

Also been running the same tune for 2 weeks. 0 LTFT. If it helps, the old air filter was a paper filter like a vacuum filter bag, had 1 inch folds with maybe 1 inch spread between the folds and the paper was supported by a plastic cage to hold its shape. Now its a brand new K&N. My g/s is lower but yet my afr logs are pretty much the same. I pretty much hit my targets after the valves open and the air flow levels out. 6800 to 7200 is on target pretty much dead on in all my logs since i set my wot afr to .88 a long time before i changed the filter

TechnoPsycho87

Here is a comparison of 3 logs with weather data at 7k rpm wot. Might help.

Sorry, did not think to check back in. The MAF g/s reading is very much IAT dependent as is Load. The ambient temp doesn't really tell you what the engine/control system is seeing.

If you like doing graphs, Oltmann had a good tip: MegaLogViewer MS. MegaLogViewer - Datalogs Simplified | tunerstudio.com

Much easier, quicker and manipulatable than Excel or certainly OpenOffice graphing. It's free in the lowest version. One quirk I've found to date is that the Cobb csv file has some extra characters in front of the "time" label which MLV doesn't recognize. To get rid of it, just open the file in excel and save it again as a MS csv, which filters the random junk away. Another is that it only saves the graphs as png's in spite of saying it will save as jpgs.

You can make it as simple or complex as you wish, as well as stacking up to 4 graphs of the same data simultaneously. Example attached.

Yeah, exactly.

^ I am so happy that you have a system that works for you and all the stress you can put on your car in 45 seconds. How about a thread or DIY describing your tuning process? No? Why not? You seem to have virtually infinite spare time to thread crap. Are you trying to replace MM?

Seems like Oltmann, Kane and others use graphs of various kinds successfully. If you choose not to do so, or are unable to interpret them, then don't.

ok so heres how i got mine to work. First off, you need the access port WITH the red and silver dongle. I called cobb and asked for one and they had one lying around in the shop and gave it to me for free. Withthat, simple connect both ends (car>dongle>laptop) and its up and running. Works with liveECU. im am able to view trace what the ecu sees on all tables.
