IQ drops down PPD 1.2

Postby 1komma9pd » Thu May 08, 2014 1:20 pm

Hi,

after flashing the new file with IQ Limiter set to 75mg the log looks still the same like before.
Engine is BMN
Here the log before flashing (iq limiter set to 70mg)

rpm > IQ > wish > torquelimiter > smokelimiter
2863 >67.5>403.0> 392.0> 407.4
2935 >67.6> 401.5> 392.0> 407.0
2985 >67.8> 400.0> 392.0> 406.4
3052 >68.0> 398.4> 392.0> 406.4
3114 >68.2> 397.1> 392.0> 406.6
3164 >68.4> 395.9> 392.0> 406.8
3236 >68.6> 394.4> 392.0> 406.8
3285 >67.7> 393.0> 392.0> 407.1
3337 >62.0> 391.6> 368.0> 404.6
3387 >59.8> 390.4> 354.0> 404.6

3440 >60.5> 389.2> 348.6> 400.4
3486 >60.2> 388.0> 351.0> 401.6
3536 >61.0> 386.9> 354.0> 403.3
3582 >59.4> 385.9> 351.9> 404.0
3632 >58.9> 384.8> 344.1> 403.3
3678 >58.4> 383.5> 341.7> 403.3
3720 >57.8> 382.5> 339.7> 403.3
3758 >57.5> 381.5> 337.4> 403.2
3811 >57.5> 380.6> 334.9> 402.6
3951 >38.8> 379.5> 333.3> 402.0

Why there is a drop in IQ @ 3300 rpm ?
After setting the IQ limiter map to 75mg no more fuel was injected, still 68mg at max :x

Could someone find the problem?

Or is it still the same like the boost values :?:
VCDS only shows 1.5 bar but the turbo makes 1,7 bar as set in the software

another question
maybe the exhaust temperature limits the torque?
I found in the web for PPD 1.2
7C174 - Torque limiter via Exaust Temperature 16x16 , x axis factor 60 offset 100, y axis 1 , factor 0,031250 offset -1024

the map could be found in my file @ 7C128 or am I wrong?
and the offset didnt make sense or are these correct?

1komma9pd, you need to change Smoke limiter.

VCDS shows 1.5 bar becouse you have not changed MAP limiters.

Torque limiter by EGT is 7BDA8 16x16

In VCDS, G10Field 2 Boost Pressure seems to be limited at 2601.0 , so you should see values above 2500
