VEMS firmware versions

[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

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?

well not on my laptop.i will try again but i doubt it. yours was working with weird ways...

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.

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

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

[Jamo]

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.

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.

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.

Gary, it is always ongoing...

now that i have the headphones i will recheck for knock and im always adding something to finetune things!!

Vas check http://www.vems.hu/wiki/index.php?pa...2FFero%2FAudiS

Got the vemscfg from there and he is using the boost alternate pwm table instead. What's the difference between them?

megamanual is great. not sure if its all still there from ms1 days. i had am msns setup for the 16vt to run on dizzy. never fitted it though. learned a lot from there and i really miss the use of megatune on vems.

[Jamo]

Cheers, been looking more and good the config is all over the shop multiple references in various ini's

Ah well at least i'm starting to understand somethings, i'll have to read megamanual though as the items still apply to the megatune values
