Speed sensor-VEMS

This now seems to be working and apparently the settings for the audi's is 112hz/100km.

needs to be rising or falling, not both. Noise automatically calibrated, so.. in theory, it should help!

i havent tried it yet, so any vems users that are on 1.1.95, it should work.

So if that works, that means that gear depended boost is operational!

sounds like my boost controller is soon to be redundant

I wouldn't bank on it

I'm not sure of the benefits of gear based boost on a 4wd Audi to be honest

[A80Avant]

yes, neither would i, although boost seems to be behaving up to now nicely on vems alone. If gears work as well, then it remains to be seen if it makes any difference.

by the way, do you use gear depended boost on the electronic boost controller?

[s2martyn]

yeah your right...maybe after version 1.1.9x or later

[s2martyn]

yes i only have first gear limited to 1 bar..dont want to break anything

[A80Avant]

as 1 gear vems works fine

[s2martyn]

i am still on 1.1.63 not the latest ones

[Jamo]

1.1.63 ? get yourself on 1.1.95 it's worth it.

Once you upgrade beyond 1.1.83 you can update firmwares on the fly without having to remove the fuel pump relay, injectors and ignition as they all get turned off in the ecu, makes firmware updates a breeze.

[s2martyn]

yes i should get it sorted..
do all settings move when you upgrade or do you have to input them again??this is one one of the reasons i have left alone...my car runs ok but is well down on power

[Jamo]

You have to reupload the config and then any new settings get added.

Then reverify everything and turn off all features you do not use, especially under the motorsport menu

[A80Avant]

also once you have gone into the 1.1.8x you dont even need to recheck the timing angle with a gun. Its always the same. But you will have to if you are still on 1.1.63

I do still take injectors and coils out regardless. i dont take the fuel pump relay though(always forget which one it is! haha

Been emailing back and forth with Marcell about the speed sensor settings and issue.

it looks that on my car it is still erratic and after sending them a trigger log, it looks like its not something that can be mended with a vems firmware, but rather an electrical connection of some sort... Or at least that is one suggestion.

However there is a query if the speed signal is taken from the dash or from the speed sensor on the transmition. It would have been interesting that since my speedo works fine, my ABS works fine and the diff lock is responding, that if the signal is taken from the dash, it could work fine!

anyway, ill update if i have any more news on that, but apparently Audis may be a bit problematic on this sector...
