	Ea113 cdl Engine Max air Mass ori lmm ? « on: January 29, 2022, 08:13:35 AM »

Hello community,
I am trying out a few things on a Cdla engine.
I have a question for you,
How much air mass do you get with the original lmm? For me 303,5gr/s is the absolute maximum which is possible. engine of course completely made and with big k04 upgrade supercharger. what are your experiences? Is that the end of the line with the original lmm and a bigger one is needed?

LMM isn't a bottleneck.
Theoretical physical measure limit is about 910 g/sec.
95% of full scale is 860g/sec.

I think you are talking about the cover integraded Hitachi MAF measure limit, not sure if the values will still be exact in these ranges because of the sharp curve, anyway such values will not be needed. I think he has the Bosch TTS MAF inside, there you will be limited to absulut 486 g/s at 0 us, stock limit is about 335 g/s at 66 us lower limit. With some small change it should be possible to have more then 400 g/s. Which is diagnostic limit?

Wrong think.
Topic starter spoke about CDLA engine.
It use another LMM, not that is installed in TTS CDLB

Yes gremlin I mean the ori lmm from Cdla Engine.

I mean it has 65mm
And the tts lmm has 76mm I think.

But I can already read here that it is probably not the lmm which is why I don't get more air mass.
I will have another look today.
