MegaLogViewer 2.81 update doesnt work??
 

I went to open MegaLogViewer just now and it prompted me to update, so i did. Now it says "fatal exception ocurred. program will exit". Is this happeneing to anyone else? How do I fix it DIY?

I had to update the Java runtime environment for it to work.....

That must be what I need to do too then. My update "worked" but my calculated lines like AFR don't show and a bunch of other stuff is fubed.

i just tried after reading this and it worked for me

Any way to disable that message every time it starts? I just don't feel like updating, for reasons like this. What I have now works fine, and if I hear about a cool new feature in an update I'll go find the update myself.

turn off automatic updates ;)

yup, there's a thread on msextra. you need the latest java runtime client for it to work properly

too lazy to read but other than that msg trying to get you to register are there any improvements in the software?

i don't like the fact that i can no longer use Ctrl O to open a file. It's a bitch to move that cursor around while driving.

I updated my java runtime, my calculated lines are still not showing up. I'm gonna just uninstall it and reinstall the old version.

haha, i'm glad i'm too lazy to update.

lazy git....

so it's all improvments, with a long term move to his new tuning proggy which sounds like it's going to be stunning.

also MLV is now classified as Shareware. it's $10, but considering how easy this guy has made it to tune and the effort he's put in, it's worth it.

I just updated, didn't have to update my java. My MPH calculated field is working fine thus far.

Agreed, it's well worth it-- Phil busts his tail and has made one of the best datalogging and VE tweaking apps available for any EMS and he's not stopping there, it's going to go alot further I think....

I don't know about you guys but I can't ever get MLV to tune my fuel VE worth a crap it also destroys my table no matter how long the datalog is or how much i filter out.

what are your AFR targets like? if they're to pot then you'll never get a good output.

it works brilliant for me. I need to do a tad of manual smoothing afterwards, but nothing major. If anything the smoothing just makes the graph look nicer, and not a lot else ;)

I have good afr targets setup, it still looks like crap, it makes cells sometimes dangerously lean, others too rich, i'll have cells within 1-2 ve units apart and it will adjust them so that two cells next to each other will go from 65-78 between two cells.

Do you guys have a narrowband O2 option in the "VE Analyze" Window? I have the option there but it is disabled (not that I'm going to use it, I just wanted to play). :)

The key to MLV's VE analysis is very gradual and smooth transitions. Ideally no enrichments must ever be active, especially the acceleration enrichment.

That's hte interesting part of it all. I leave all inrichments turned off when attempting to the fuel map. Maybe I need to focus my datalogs on certain parts of the map. I'll keep messing with it all i suppose.
Do you turn EGO off?

Actually, the author has noted that the VE analyzer DOESN'T actually need the enrichments and corrections turned off. The correction/enrichment levels are in the log, so they are compensated/accounted for in the analysis.

Now that's pretty damn cool.

I find it most effective to do a huge datalog, like 10 minues of varied driving. that gives the most consistent results.

just doing power 1 run and blindly accepting all changes leaves a funky VE table in my experience.

Yeah i usually do 10-20 minutes because my "good old backroad" that i drive on to tune is 10-15 minutes one way to the first stop sign.

I've also never had anything but excellent results when I've road tuned a VE table with VE analyzer. I've never tried to tune WOT with it and I'm not sure that's it's ideal purpose, but it's been great for dialing in VE around low load cruise areas of the table.

I've found that turning off the AFR Target table while doing a tuning log/run give much better results. It makes sense since all the log would show is the AFR and not the adjustments it made behind the scene to attain those AFRs. So then VE Analyzer would be making changes based on what your VE table shows, not what the MS was actually delivering for fuel to reach the target AFR.

It'd be like you turning your oven on to make a pizza, then your girlfriend coming in without your knowledge and changing the temp on the oven. Then your pizza is burnt or undercooked in the recommended time. So the next time you go to make a pizza you adjust your temp setting up or down from your original temp(not what she set it to) depending on if it was burnt of undercooked but it still comes out wrong.


Anyway, that made sense to me and I was able to achieve more consistent results and a better tune once I realized that.

See, that's the thing. The datalog DOES show the enrichments and corrections applied. All the information to know exactly what the MS was doing is in the log. Hence the power of MS, and why VE analyzer is way better than the old MSTweak 3000. MSTweak only loaded the simplest of logs, where VE Analyzer uses the entire log to change cells. But if you've had better luck with AFR targets turned off, then great.

I've done plenty of power runs and used the VE analsyer, it's extremely good, the usual caveat applies i.e. use 4rd or 5th gear to slow everything down (apart from your landspeed ;)) a bit :)

just out of curiosity, what columns would those be if you view the log in excel?


everytime i used VE Analyzer with targets tables enabled it would keep going back and forth with recommendations for the fueling. it'd have me enrich a cell just to lean it back the next log. and yes i need load the newly made VE table before the following run/log.

i am very happy with the results i've achieved with the VE Analyzer program. I remember trying to adjust the VE map manually before I discovered the program. Talk about tedious! gotta love progress.

Just registered Megalogviewer.

ps. it was $19.95, not $10.

hmm so i have to pay for my MLV? It is not like i use it to tweak the system i just use it to read my logs and troubleshoot.

no you can keep pressing register later :)

£10 ;)

One of the things i didn't like about the new MegaLogViewer was it lost the ability to hit control - O to open a new file instead of using the mouse on the drop down menu, kinda difficult while driving.

But today I just realized if you hit just the O key it'll start the dialog to open a new log file. much easier.
