When asking for technical help at the very least let us know the version of firmware you are running.

yes!!!

   
Which uses you.The 1.1.27 beta2 or beta3 or beta6?
Uses you firmware from the Megatune folder?
When i click on generate-config16x14.bat than i have error messages :-(
Can you upload your Folder with your files?

AVP

i use 1.1.27 beta6
when i upload an msq i only get 2 error messages.

program runs fine however.

what would you like me to send you?
here is my email: [email protected]

let me know

Hello,
here is now an art exchange business ;-)
I can sent my MSQ file with the 12x12 tables ;-)

I write an Email to you

Im happy how the car works now and how idle is managed.

i have discussed with a friend of mine who is in electronics and we will try and fabricate a good 14gage cable that will go from the car's battery directly to the ECU plug, through a relay to connect to the ignition switch and a fuse.

The aim is to actually eliminate as much as possible any voltage drop which is secondary to slim cableing,therefore allowing the resistors that lie in VEMS already to act upon much quicker in electrical drop.

Im hoping that with this mod the idle will be better managed when all the electrical systems are on,since the current from the battery will not be dropped as much.

today,
i went out for a drive and did some modifications on the boost settings, however i noticed that although i havent touched the idle settings, the car was idling with lamda 1.05-1.06 while previously was @ 0.97 to 1.01.

i dont use EGO correction on idle and i was startled to see this.On the other hand, EGTs were fine on idle but the idle itself was not as smooth.

i dont understand why this would happen. The IATs were not that different than other times in general,other than the weather being a bit foggy and humid.

i didnt change much the VE settings for now,i just used EGO correction from 700rpm so that at least i would have a proper lamda value.

can someone give me some input on this?

Hi,
The air will be denser under those weather conditions, so the extra air will make it run a little leaner.

what do you reccommend doing in these conditions?
i wouldnt like to change back and forth settings on vems for this...

i now used EGO correction on idle so at least i get a proper lamda there, but i had to increase my idle bins on VE from 70 to 72.

should i just leave them as it is, or put them back to 70 and ego on?

Bat

Hi,
Ego correction should be best as it will do the work for you.

ok.will do that!

for the time being ill keep the ve:72 and see how it goes

how big of a difference can 3-4 deg of advance can make in power output?

im having a puzzle. According to my perfomance box runs,if i compare runs with motronic and VEMS i get as much as 20hp difference on a range from 5000-6300rpm where motronic produces most of it's power, although VEMS produces usually around 20-30hp less on those areas.

differences are about 0.1bar of boost less on VEMS (maybe) and about 3-4deg of timing difference( mot:20-21deg and VEMS 16-17deg)

can those differences justify the amount of power difference?

runs were made on different days, but on same road.I know that temperatures play a role as well, there might(not sure) have been a bit colder on the motronic

gunni

20HP from 3-4deg timing change is totally realistic.

AVP

Oh good.
that is good to know
i had to stiffen the wastegate spring a bit to match the boost i was getting on motronic and now i believe it drives better.

i will leave the timing as is for now, although motronic had 22.50advance on high revs and it also gave +2 deg on lower IATs, i only use 16-18deg for safety reasons.

i wonder if that feature will be available on an official firmware on vems as i believe that lower iats should be available to provide more timing and not having to use the highest possible timing on the map,and expect that to be retarded depending on the IATs graph.

that firmware 1.1.50 and newer has.

AVP

yes i read something about that, but i would like VEMS people to actually make a NEW OFFICIAL firmware update, as soooo many different things have been optimized and noone can actually use them until they are deemed that they are working properly.

how much more testing is there needed????
