Vems firmware 1.1.81 has release status

[A80Avant]

good stuff
thanks for that config!

I dont know which boost valve this client is using, i guess it was the standardvalve from the 3b.


I think it was like 1,4bar up to 5500rpm and then raises to 1,7bar, every engine is different on this point.

It runs on Gasoline @ 93% InjectorDC.

What turbo there that maxes the injectors like this?

I think is was an RS2 turbo, maybe something bigger? Dunnu actually

[A80Avant]

its a bit strange to have to use 600cc injectors up to 93%DC on an rs2 turbo only. I use 630cc injectors on 3076R turbo and barely get 65%dc on high rpm/boost

Well, to be honest. It´s just what he said he had - could probably be smaller injectors.

[A80Avant]

i see. thats ok

Right found something else with the new vemstune 2010.10.01 pay attention to the injection group table.

Any output that uses an inject output will now show in this table with a tick

There are 3 non injectors as a minimum you will see in there, fuel pump, idle solenoid valve and boost channel.

Do no untick any of these options from this screen, if you do no matter what your settings the channel that is unticked will not work.

I so love when they add functionality like this to vemstune and don't document it!

you lot have been busy whilst ive been pig sick with flu.

how was adi.

ive not made any changes since last time. im gonna tweak ve again soon. and as a consequence startup. once im happy ill look at 1.1.81 and go to then darkside (vemstune)

[A80Avant]

yes, find something that works on your version first.
myself, after increasing timing on cruise quite a lot, i found that keeping lamda to the leanest extremes is not helpful, consumption went up again, so i made it a bit richer and it seems to be helping. So back to lamda 1.06 to 1.09 instead of 1.13!

Some help pls:
Where and how do I connect the switch for the map switch option?? I have the following spare:

pin1 mcp3208 pin6,ch5
pin2 mcp3208 pin7,ch6
pin3 mcp3208 pin8,ch7
pin4 EC36 pin 34 (power out)
pin5 EC36 pin 36 (power out)
pin6 GND

I recall reading somewhere that I simply need to ground it but I better ask!!!

[dkw_dude]

i used ch6 which was available on my VEMS, connected it to ground as you say, worked for me. Remember to burn/flash before you try the switch!

Think I had to upload the complete config after switching to "B" as it's empty/full of rubbish. And then adjusted the parameter for switching back (ch6 OFF switches B-->A), then validate config, I found that ch6 was used by functions I didn't use (launch or something). Cleaned up the config, burned/flashed it and was able to switch configs . Thats how I remember it, had to fiddle a bit before I got it working. I had the A6 standing by just in case..

[Billman]

So you used the Pin2 on the connector that runs channel 6 through the mcp right?

[dkw_dude]

What is mcp?

It was prewired by Pnanassy, the VEMS came with an adapter cable VEMS --> Motronic 55. Out of this cable there was 2 unused wires for inputs, and one for gnd. Measured which wire that connected to ground, and tried different channels for the config switch until i found the right one.

Don't know if it's different hardware on different VEMS boxes. Mine is V3.3, bought it September last year I think.

Same as mine, plug and play are different they have to find a spare pin to connect too

[Billman]

Mine came with motronic plug and has an extra 6-pin connector with these posititions. i just dont know what to use where. i posted also a question on the vems forum.

I think I found it! It is an mcp connection (mcp3208 chip) pulled to ground
