Hello.
I am trying to calibrate some Firad +160% injectors on a Ibiza 1.9TDI. All worked ok except I can't go over 100mg on IQ. I tried changing the diagnostic limitations from 39 70 to 39 255 and factor to 100 but it still shows only 100mg. More so it also limits the actual IQ as the duration doesn't exceed 20 degrees. I even tried changing the formula and used 18 25 with factor 100 and it did nothing. Still upper limit 100mg. I would like to see the actual IQ and not decalibrate duration maps with 100mg and 40 degrees which is over 200mg. This way I can control MAP smoke limiter better and also have realistic MPG on the trip computer. Does anyone have any idea how to raise the limit? If it is even possible?
I don't have the file available on this computer but if it is necessary I can upload it. It is a EDC15P 038906019LA. But I guess all EDC15 have the same IQ limiters, it should be the same regardless of the ECU.
Thank you

we must see what u have done
and i have no time to check all maps

Here are 3 files I modified real quick.

First is ori
(255/256*70)=69.7mg
69.72*3.64=253.8

Second I raised the limits from 70 to 100. Did this on lots of cars and always worked ok. (ARL tune for example where I inject 80mg).
(255/256*100)=99.6mg
99.6*2.56=254.9

Third is where I tried to raise the limit to 250 mg IQ. And it doesn't show more than 100 on vcds. Also it limits actual IQ at 100, so it's not just a vcds limitation.
(255/256*250)=249.02mg
249.02*1.02=254

I am sure there must be another limiter, but I don't think many bother with this. I could just set 50mg at 20 degrees duration and treat the 50mg as 100mg in the dw torque and smoke maps but this would screw up the MPG readings in the trip computer. It is my car and I would like to see on VCDS what I am actually injecting.
