VemsTune and 1.1.6x release

[dainiuxsky]

HI

1.1.67 Super Boost controller , knock detection only after 7200 rpm  ::) tried on 3 different cars Audi AAN, 3B, and 1.8T.
Knock Diff gauge always aktiv after 7000 RPM I tried various configurations, almost the same.  ???

sorry for my bad English.

sd card loggin on? there is no knock detection when sd log on..

namely without SD card.

dainiuxsky, what you mean with super boost ctrl?
Is it working perfectly and easy to tune at same time?

Older version of rails under linear control.
Current individual map, you can put there owerboost where needed and partly to speed limint. :o
Should still analog input 0-5V can be the total pressure regulation as an external boost controller. ::)

Okay, so I got the latest VEMSTune, uploaded the 1.1.68 firmware to an ECU, and took a step-by-step approach through...
So now I have a couple of WTFs:

MAT/TPS Fuel
MAT/TPS Ignition Retard
What are the X, Y scalars? X=MAT and Y=TPS?
How they are they scaled? MAT I'm guessing is -40degC to 102degC is TPS % or some notional value?
And the values in the tables... are they % biased around 100% or some other value?
What values should be used as defaults?

MAP correction, what are the axis units? What is represented in the table?
What values should be used as defaults?

Acceleration Enrichment, a lot of this seems self-explanatory, but... what is the ign retard amount?  And the fuel film?
What values should be used as defaults?

Its looking good and has some good usability features.

I can upload my config tomorow, 1.1.68

[dnb]

MAT/TPS Fuel & Ign tables - yes, axes as described.  It depends on if you use the flash table scaling or the 14 point table (which can go to higher temperatures IIRC)  Usually -40 to 102c is OK.

Sensible values are the usual values from the ideal gas laws with a rich bias to guard against idle heat soak, plus a rich streak for safety at high temperatures at moderate throttle.

MAP correction

Table populated with 100 for everything in my case - not using forced induction with throttle bodies on an alphaN strategy!

Acceleration Enrichment, a lot of this seems self-explanatory, but... what is the ign retard amount?  And the fuel film?

Retard ignition while accelerating.  We had a chat about that & turbos some time  ;)  Fuel film looks to be a time based smoothing filter for evening out lumpy steady-state running.  Good for big cams.  I have played with it but haven't made my mind up yet about it...

If you have your firmware and temp tables flashed, can you go into VemsTune and use the 14 point temp sensor table? Or do you have to upload firmware without temp tables?

[mattias]

The curve that you can define yourself, or use a good default from the dropdown (configlet), has 17 points.
It's just an option, if you want to use that curve or the curve in flash memory, no special firmware.

So where are my cranking, afterstart and warm-up enrichments?
They didn't seem to appear in the workflow, the < and > keys assist with the workflow of setting up the system.
Nicer still would be to have a standard config with everything set to 'off', I have been told by more than one tuner that they would like to be able to start with every feature set to 'off' or a value that does not have an effect on the primary settings.

Sometimes knocking take place at tip-in. I hope ignition retard here can help.

But regarding fuel film - it works perfectly for acceleration. Andrey described it here: http://www.vems.hu/wiki/index.php?page=MembersPage%2FAndrey%2FFuelFilm
Since this acceleration becomes as it should be: no lag, no overflood, crispy.

You can't miss them. They have their own tables.

Here is my config for 1.1.69 for my BMW M20 engine : http://media.vems.se/mattias/bmw-m20-1.1.69.vemscfg
I have an ICV installed, other than that it's a pretty basic setup. Just drag and drop my configuration file over the dialogs and tables you want to copy and you should be set to crank it.

Analogue input chanels

Is there any way of getting displaying the spare ADC inputs representing temperature of the sensor connected to a spare ADC chanel?

For example.

A configureable five point temperature scaling for each volt of the ADC input in vemstune creating a crude temperature curve, or, similar to the coolant and MAT sensor dialog tables.

It would be nice to have two ADC chanels with this for monitoring. A single round (which I intend to purchase) could then display a believeable value that actualy represents tempreature, rather than volts requiring manual scaling to temperature.

I spotted that there is some sort of ADC calibration tables, but I am not sure how this would work with temperature sensors wich are non linear.

Could be for mesuring oil temp or pre intercooler temp for example

I really don't want to have to resort to a seperate datalogging system when the possability of doing it with Vems is real

I have to point out the drag and drop function - its awesome.
Open the window you want, go to the configuration file that you want to use on your file explorer, drag the file onto the target window, drop and the values are updated.

Brilliant.

Viewing logs is a major pain.

When I hit play, nothing happens. so I´m forced to drag the slider around and that has a resolution all on it´s own.
will this be updated to fixed soon?

Give me a step-by-step bug report and I will make sure that the developers know about it.
