Hi

i just updated my Vems to the 1.1.81 firmware.

Attached a screenshot from the new feature.
I have no idea how or what to adjust here.
I am running ID 1000cc injectors and Catcams No.2303 i think.
I am thankful for any information.

best regards

Hi.

A good starting point would be to just use 3 rpm bins, like 1000, 3000 and 6000rpm, just enter like 20000rpm´s on the rest.

Then just let the engine idle while adding angledegreese at 1000rpms, probably going to be best at ~400-450degreese.

Then cruise on the road att 3000rpms and try to tune that bin to a nice angle, then you can probably see a pattern and figure out what to put att 6000rpms. The ecu interpolates between the rpm-bins so having one each thousand rpm is a waste of tuning time.


Cheers and good luck.

Drivability, throttlerespons and smoothness, thats why this function is added

[Jamo]

Watch Lambda, you want to adjust the angle until it's at it's smoothest and the lambda is at it's richest, if you adjust it and it goes leaner the setting is worse than the original setting.

Or so i've been told...............

nice info. I now have a 1.1.81 config with most my settings from 1.1.27 dialed in. Upgrade in the next few months though.

by the way, is it true that in case you want to go from 1.1.8x back to 1.1.27, it is easier to do by using vemstune from there on?

if you do switch that way, can you easily go back to 1.1.81? (only asking because im not sure how much free time i will have for some fiddling, while needing the car to run right everyday practically.)

thanks

It is you lazy git

For the I5 the best starting values are 280-360 from idle

Beyond that your on your own, I need to test this all out now on the engine live

[Masterblaster]

I will try some settings the whole saturday.....

think ill have enough just with megatune lol.

ill let you all know how it goes. i have one particular lumpy spot around 2k im hoping this will help with.

your 100% on the lazy. i like to think that i helped sell vems to the forum lol. the rest is the desire of the members such as yourself who push it onwards and upwards.

nothing too crazy. I've bought a pair of netbooks and both work great on vemstune. Acer Aspire one and Asus EEE.

[Jamo]

I have to agree, my laptop I had to run megatune grinds to a halt with VEMS tune ( it has a serial port ) I have to use my other laptop full time now

[GazzaG60]

i got 3 or 4 laptops here. the current one im using is a 10yr old toshiba. the batteries are far better than dell.

ill try to make up a d610 again.

You can try to change the Graphics Quality Factor.


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