VEMS firmware versions

[Jamo]

well with alternate you are specifying solenoid duty cycle, while with boost you are specifying map wanted. I kind of like the latter because it is more down to earth to what i ask from the boost,rather than using a duty cycle value and expect to see what actual boost im getting.

i leave the duty cycle mumble to the ECU to figure out

I understand it's same as my EBC then which has the same dual modes.

The alternate will work quicker as the ecu doesn't have to calculate but it's harder to setup as you can't the see the human interface i.e required boost directly.

i think the ECU has enough calculating power to do that calculation.... damn thing is 128bit (i think).

anyhow, it works nicely now with the 1.1.27 so i wanted something that is the same on my future version.

Cracked it! Uninstall vemstune

Install the 2009-10-02 version first then install the 2009-10-21 version next and the bug doesn't happen

Thank god that's over.

you mean install the 2/10/09 and then install the 21/10/09 without uninstalling the first one?

[A80Avant]

am afraid its not.

i installed 2-10-09 and actually the boostcurve table was fine.
i then installed on top of that the 21-10-09 and it went back to kpa/kpa again!!!

Nope definitely works, I also installed all the firmwares when with version 2/10/09 before updating 20/10/09

I've done it on 3 different computers I have access too.

It's the firmware installs that does it. I've checked the directories and they have a lot more files in than previously.

[A80Avant]

so basically i have to uninstall the all vemstune and firmwares, install the 2/10/09 vemstune, install 1.1.62 firmware and then immediatelly after that install the 21/10/09 vemstune?

[Jamo]

Quickest way is just delete the vemstune directory ( backup your work ) install 2/10/09

Go into tools / firmware / firmware webtool

Download the firmwares to the hard drive that you want ( I installed them all ) then in the right hand pane right click on the firmware number to install it ( this isn't done by default! )

Once you've done that install the later version

processing...

[A80Avant]

.....and still no go.

Jamo i followed your instructions to the letter. Erased everything, uninstalled VEmstune, reeinstalled 2/10 uploaded the firmwares i need (1.1.27 and 1.1.62), closed the vemstune,and then clicked to install the 21/10. Opened the new vemstune and again kpa vs kpa!


could there be something in the registry causing this?

[Jamo]

Only I did which I didn't think was important was open up a valid config in 2/10/09 before upgrading to the new. Try the attached.

Don't know what to say mine works :mischeif:

[A80Avant]

i opened the s2 3B one and i still have the kpa vs kpa there.

i will try it once again with opening a config on 2/10 before going to 21/10

suppose thats the nature of flaky SW. for some it works for others not.

do we know why megatune is no longer supported and usable.
