I will be upgrading a.s.a.p and having a play hopefully before ADI

hmm interesting...
what does it mean excactly: do not try to set anything manually? upload a 1.1.81 config and then make changes? or what? -
On all new versions you should upload a config so the ecu fills all missing data values used by the new features in the firmware with sane values.Comment

haven't put many miles on it yet but I can confirm it runs fine from initial impressions. the "big new thing" is the injector angle support, I haven't had a ton of time to play with it yet though. supposed to greatly improve idle characteristics for those of us running big injectors.Marc Swanson

eventually its a possibility. too early to tell yet, I like to more thoroughly test before I go shipping boxes. Currently I ship 1.1.74, which is a clean migrate to 1.1.81 anyway.Marc Swanson

i see what you mean. Currently the latest vemstune comes with 1.1.80 config only though. is that the way to go?Comment

1.1.81 and 1.1.80 have the same features, the ini only changes when features change in the versionComment

bikerjim.
the firmware is the changes in the code to allow differnet features. quite oftem as one feature is gained anothe ris lost.
the ecu works around a cpu that is the same in one respect to almost all cpu's it deals with inputs and uses conditions to provide an output. so for example. the input is AF reading of 1.2 lambda. for this set condition the ecu want to see 1.1 so it changes the on/off to the injector so that the desired target is reached.
there are lots who dont understand at all or fully. dont worry. that includes me. we all learn as we go. most of the posters in this thread i think, but coudl be wrong, other than marc and myself had no mapping experience prior to vems. the learning curve when you have said ecu in your hands is very steep. im sure jamo and vas will agree.
the basics of vems are there are 2 main programs to tune it. megatune and vemstune. firmware is features and fixes and up to 1.1.44 its megatune. after theat its vemstune. versions 1.1.23rc upwards run an I5 just fine. being a realist id expect jamo to have a better idle due to the newer firmware he has in operation. thats the only bit im really interested in.
any questions feel free to pm me if you like.Comment

The new idle routine is a huge improvement but my major improvent in idle came from changing injector type.
An injector is not just an injector I have been taught and it certainly showedComment

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

Wrong screen, the new option is under base setup / injector angle curveComment

it's why I'm so interested, my idle is good at present but the 2 people i've spoken too who have done it on an Audi S2 say the angle has made a difference
