Sorry, what does that mean?

Is the idle vacuum condustant ??

 

 

Sorry, what does that mean?

 

i mean constant 

[TFD]

No, idle is not stable:

 

 

A vacuumleak should not cause this I think, because of the TMAP sensor.

The idle is hunting a bit.

Take a look at the ignition at idle:

 

Above graph is Chill's car at idle (old file I had around) and the below graph is my ignition at idle. Looks all over the place...

 

 

[TFD]

Also noticed that Chill's throttle/fly % (throttle-tab) is lower then mine at idle. Could be a cause? Will try out at home.

Is red the throttle pedal position?

[TFD]

Yes it is the VALVE.

Good thinking. So something makes the valve bounce open/close. This does not happen at Chills log.

 

Dodgy TPS? No DTC's popped up.

I thought red was throttle valve position not pedal Key is on left hand side

[CHILL Gone DUTCH]

But it needs opening up to see full discribtion

bottom red is throttle valve (TB) 

bottom black wiggly is ignition 

 

and top blue is map 

[CHILL Gone DUTCH]

TFD what date is my log from 

 

[CHILL Gone DUTCH]

Also look at the log and select the two pedal position tick boxes (pot 1 and pot2)

 

 

number 7 red and blue 

 

should work opposite each other

Top blue is your ignition, not the MAP. I've did some PAINT-skills over there to make a comparrison.

[CHILL Gone DUTCH]

i will send you my email- by pm 

 

send me your log and i will take a look at it 

[TFD]

You allready have my log in your mailbox

 

Here's the comparrison:

 

 

The Throttle pedal stays at 0%, but the throttle valve fluctuates in my log.

Is that cold idle or warm?

[CHILL Gone DUTCH]

i would alter the throttle map and see if it improves, 

will take a look at the log now ( i forget  what i have ) 

 

 

[TFD]

Is that cold idle or warm?

 

That's warm. But some issues as well when cold.

[CHILL Gone DUTCH]

i wonder if the ecu is telling the throttle valve (TB ) to increase to stop stalling 

 

try and increase you idle RPM to 1000 from 950 

i noticed the rpm is dropping below 900 so ecu might be trying to compensate

 

also have a play with the maximum throttle valve speed in the transient tab 

 

 

 

 

 

 

[CHILL Gone DUTCH]

might be worth trying my transient setting on that whole page as there quite a bit different from yours
