Vems firmware 1.1.81 has release status

[Jamo]

You can try to change the Graphics Quality Factor.


Preferences -> Environment - and switch graphics_quality_factor to 1 instead of 2, and restart Vemstune.

Well there's a nice tweak to know

netbooks?? that is brilliant!

do you use any specific serial to USB adaptor?

what is the PWM frequency used for the IAC valve from most audi users on 1.1.81?

On 1.1.27 i had to use something like 110 on the similar bin to make the iac respond relatively ok, but there is no 110 on the 1.1.81. It only has 100!

Marc suggested 25. Any other choises so far?

unfortunatelly the different location of the IAC also plays a role in idle maintanance...

guys. ive decided to try.

so i got a 12x12 hi-boost 1.1.23rc config. im willing to redo it if necessary. is there an easy import option.

should i go for a 16x14 first though?

i got the 1.1.27 but only 12x12. i got all of the 1.1.23rc ones though but thing vemstune is only 1.1.27 upwards?

[GazzaG60]

edit theres now big differences since i last looked. 1.1.23 is there.

I'd advis to write an offline map to go from 12x12 to 16x14 I found if I did a straight conversion it would put my values all over the place ( this was with 1.1.65 though )

To this end your may be better going for 1.1.74 then going 1.1.81 as you can't do an offline 1.1.81 map until you've upgraded the ecu.

[GazzaG60]

so jamo.

at what level did you go from 12x12 to 16x14. thats always been my issues. your correct it does ****** up the placement of code.

is there an upgrade procedure from 12x12 to 16x14?

[GazzaG60]

maybe best to do the 16x14 first in megatune?

[GazzaG60]

first attempt to create new config in vemstune - crash.

You could do, false economy for me as your have to upgrade 1 more step

I copied the values from 12x12 into the 16x14 map added some meaningful break rpm and map points then used the vemstune remap option to get it into the values I wanted.

Vemstune then shifts the values according without you having to do any manual math.

[GazzaG60]

say that again in english. lol

so you can do copy in vemstune?

so what i should do is save the map as a vemstune file from the car then import it into a 16x14 config?

[Jamo]

You using the latest VemsTune-Install-2010-09-08.exe?

[GazzaG60]

yes. i tested on my x64 windows 7 laptop. i am as we speak building a dell x300 with windows xp. this should be a better option.

so whast the best process to get a clean upgrade do you think jamo. the issue i had when creating a new map in vemstune last time is i couldn't find the ignition tables for selecting the sequence etc.

If you want to do that way then you would have save the 1123 map in vemstune, upgrade the ecu to whatever version, re-upload the 1123, vemstune will add all the new scalars then save the map from the upgraded ecu

Work on the map offline, re-upload to the car

[GazzaG60]

so is vemstune only 16x14? it will load the 12x12 and convert itself?

sorry for the newbie q's. i got a network upgrade on this weekend but feel the car is of more value at the moment.

as a software man how would you do it.

[Jamo]

There's no option for table sizes all are now 16x14 so yeah it will convert the table to 16x14 but your data be all over the place!
