Hello, I'm having problem with injecting more than 65mg/str on that car. No matter what I do, ecu just don't want to inject more than 65mg/str except if i cheat duration, which I don't like, the torque from logs still looks like stok, so I think I've missed some TL. Can someone have a look at the ori and the mappack and say if I've missed some IQ or torque limiter? I'll be very gratefull.

P.S. I didn't added SOI and n75 maps because no need of them right now.

Here. Torque Limiters are flattened like that just for testing puroses...

Your tune is completle mess. Look at your Nm/iq maps last column(completle deleted(no iq, at all)), Look at lamda maps last columns(not edited on high maf(STOCK quantity)),. Why you lowered duration map in the end? Turbo pressure +400mbars?

First of all the nm2iq map last column is zero because of the popcorn limiter the ecu can switch between torque limiter and nm2iq and the pops are better. Second this turbo holds up to 1.8bar without problem its successot gtb2260vk holds to 2b at those engines without problem. I didnt noticed lambda maps last column will have a look. I dont want you to rate my tune or to tell me how I'll kill this turbo, just if you see any problem for the iq limitation. Thanks :)

P.S. Duration is extrapoleted if you dont see

you can try to modify these curves

Thanks, but that doesnt work. There is something I dont understand: in front of lambda maps there are 00014 00016 axes and when the map is like this it doesnt look full really. Can someone explain?

Hello

I think Lambda map are properly defined. Some are 14x16 and other are 16x16

Try with CD67E and CD6D0.

Thanks, will try tommorow and report. BTW in bmw edc16cp35 there are IQ limiter by coolant temp etc. but in here I cannot see them. I see something that looks like axes for those maps (CDC48 2d mode) but no ID nothing... very strange sw in my opinion...
