BACK ON TOPIC.


I've been logging my AFRs in boost vs. my AFR Targets. VE Live is getting that **** pretty damn spot on without any effort.


also, I dunno why, but my wastegate cannot hold 12psi anymore and I'm now constantly boosting to 16psi....it's fun.

 

1. It truly is the best thing since sliced bread.

2. I sense a new motor in your future .

 

1. Yeah it's neat.

2. Nah, i figured out the issue: I'm a retard.

 

<threadjack>
I'm sure it wasn't as bad as my friend's screw-up. He kept overboosting, when I looked at his car the first thing I noticed was a vac line running strait from his BOV to his wastegate actuator...no boost reference in sight.

Oh, and were you serious about getting rid of that vband wastegate housing? You never responded to my PM.
</threadjack>

 

well, I put my vacuum line on the wrong wastegate port when I was fooling around with it over the weekend.

yeah, you gotta pester me. I actually have it in hand now at least, I'm getting closer.


Yeah, VE Live is doing a damn good job I'm going to have to say:

(look at targets vs actual on the bottom)

 

How does the map look though? I find aesthetically it looks horrible!

I think I prefer using MLV as I can sanity check any changes against a datalog log. just me though, the live analyze is very impressive non-theless.

 

My map looks like a monkey bashed his fists against the number pad. Now, with that being said....Does it matter? If the logs show a dead on fuel curve, why not just roll with it?

note: that second part there was a legit question, anyone have an opinion?

 

I dunno. I think I trust the monkey fist numbers since its smart enough to interpolate between the cells. It kinda seems to know what its changing and how it smoothly relates to the cell before it or after it. Thats just my fuzzy logic on the whole thing.

 

What's the big deal with aesthetically pleasing fuel maps anyways? We don't live in a perfect world, and in a perfect world our engines would run as smoothly as your pretty ******* rainbow fuel map ****. If the AFR is fairly smooth, and it revs to red smoothly in all throttle positions, it's doing EXACTLY what I'd want it to do. And that's exactly what it is doing, and exactly opposite of what the MSPNP map ever did.

 

All very fair points, but it just grates, know what I mean. A smooth map you can take pride in.

Meh I shouldn't worry about that **** I have other more important stuff to mess with on the car!

 

I understand, I'm a little OCD too. But coming from a car that's been running like **** for months if not years with the bandaids, it's a huge huge huge improvement and I don't care at all what the fuel map looks like.

 

I mean, it works....

I went from this:



to this:



this was over the course of a week. I'll more than likely go back in and smooth out some of the outlander values.

 

ha...I love this 16x16 business...


my old map:


(the column 4K where the numbers are low were fixed...that was MLV fail)

 

Man I wish i would have taken a shot of my old "smooth" map. 3 runs of the new autotune and it looks choppy at first glance, but hovering my mouse over each cell it starts to make sense when you can see your targets and how they were interpolated from my 8x8 target table.

Needless to say the drive is butter smooth now and I think its partly because I started tuning with AE left on.

Does yous peoples tunes withs overruns ons?

 

custom filter [tps] > 1 or something like that.

 

Cant wait to use this.

 

I've always had an issue with MLV mainly offering me a tune that suited the way I drove for that particular tuning session. I know auto tune works in the same way, but live. If I drive through all the gears quite slowly (stuck in traffic or queueing around town) I go through parts of the map that I've spent most time cruising through the streets at and because I've been sat in these cells for 90% of the time i.e. 2300rpm/45kpa, if I then drive through that zone in lower gears, I go quite lean and power hesistates slightly (18:1). My way around it was to manually go through logs and dial fuel back in to those areas so that rolling through gears slowly at part-throttle wouldn't run me lean but then rely on EGO to take it back out in these areas when Im cruising in those cells again in a higher gear.

I've always logged with EGO on, AE and decel on.

Maybe I should let auto tune make my map over the course of a week or two and go from there?

 

i auto tune to and from work each day until it really just changes numbers back and forth.

then ill tune on the highway, once or twice and let the EGO handle the minute little variances.

I'll probably stop using this feature after next week.

 

How many of you are using this to tune boosted cells?

I was skeptical, but I tested it on a long straight road. I made sure the throttle came on nice and steady. I could feel the car make more power as it tuned the fuel.

My map kinda looks like *** as well. There is a really deep trough through it in 3d mode. I think it is due to the fact that it can dial in the cruise rpm so well. Lets face it, the cruise cells are only a small part of the map. Under hard accel you probably don't touch the cruise cells.

I'm going to tune for a week and then let it be. I tried to hand smooth my map and my car started to run a little rough.

This just goes to show how unique everyones setup is. I think it would be interesting for a few of us to start with the same map and see what we end up with over the course of a week.

 

Anyone offer some hand holding to transfer from MLV and MegaTune to Tunerstudio?

I am a green horn newb to MS. Cut my teeth with a DOS version TEC2. I have been making it ok changing somethings with MLV and MT. I'm a bit nervous to go to TS.

I have gone in and changed some of the INI's to show my AEM-Linear AFR's and such. When I imported an MSQ and tried to upload to the ECM this morning it gave me some error and asked if I wanted to continue and I chickened out.

I also have AEM AFR issues with MLV and MT not reading the same AFR's. I have read the posts and have not changed the 9.?? value yet. I think I might have a ground issue to take care of first.

I think I need to start a new post on questions about a car that is new to me.....

BTW I can't find the AFR Target 1 on my MLV graph? Thanks
