So a short feedback, motor is now running.
Allding your map had made no difference. I had to set a table to -1000 so it worked. (under pressure trip Thresold)

so now to my next problem, and is my injection time is 1.383 ms. (after all the corrections)
but in my base fuel table I have 5 ms in it. no matter how much ms I enter there, the lambda does not change in standing

Changing those values to 5 will not do anything unless you're actually in those cells. Which at idle and even off idle...you will not be.

Although in saying that, either your map sensor is faulty or not calibrated correctly

ah good you sort the cut out yourself :)
I am pretty sure the reason you dont see any changes is cause of below, have a read on how the fueling logic works.

yes I understand with the multiply, however, I see absolutely no distinction in the fuelfinalpri1
see pictures
once with 0ms and 10ms. everything remains the same.

Exactly what base map is this ? what vehicle ?

Whilst yes there are many factors at play, even the base fuel table 1 seems very odd, with high numbers at low loads, and low numbers at high ?

But that base fuel table 1 does seem to be the primary fuel table.

And why is your map sensor not reading correctly...if it's not working, what else is not working ?

in the petrol table is nothing set or else what please do not consider =)

the sensor works only from 100kpa, so the looks on the table.

the base map is from syvecs and the engine is a 2.0 tfsi

In the log you provided, the map sensor reading is stuck at 1100-1300mbar range. These are typically boosted numbers, positive pressure. Although not familiar with a DI engine so maybe these need to be like that ?

It's blended 100% to the secondary load table so the one you posted will have no effect, try the one I put up a picture of for you mate.

So the way I understand the set up is as follows:

Engine fueling is governed by the secondary load table (TPS) and is blended to be 100% at all MAP values as per screen shots I listed.
FYI, the MAP variations are accounted by with the SMPM (simple manifold pressure multiplier), you find this under the corrections tab.
Take a look at these maps listed and adjust them for the TPS v RPM and idle value you want, and you will see an end effect to the inj pulse width ;)
I forgot to add, you will overall be controlled by the CLL target table, so if you want to see a change in the inj final time you will have to turn that off in the said load points by inputting in a value of 0. Sans doing this any changes you do to the referenced load points will show up as effecting the fuelMltCll1 ideally when your main fuel map is 'correct' then this will be around 1.000, with lots of hard work under all conditions I generally make this +-2%

eg below:


p.s. It takes a good while to comprehend how all of it works, you will have to read the notes under F1 key short cut and then re read it a few times to have it all sink in, just takes time but you will get there!

the sensor is unfortunately before the throttle valve I must still change that.
