ME7.5 Hybrid F23 (frankenturbo), MAF scaled for R32 size. MBC set to 25psi on E85. I am seeing throttle cut and I think I have it narrowed down to either of two things. Boost Actual > Desired , althought I thought I corrected this by scaling LDRXN to over the map limit .  I highlighted what I think is the start of the throttle cut. |

Please don't post excel output. Post the original CSVs
xls is unparsable.

Why are you using an MBC?

Look at your requested load
This ^. I had the same issue with too high a requested load in a tune here (HS that Gonzo applied some quick and dirty repair to). It would cut the throttle at 3000 rpm under high load. Smoothed out the requested to take a hump out of the map @ that area and it worked OK after that. Ditched it in favour of working up my own from scratch, but it did correct the problem with that particular tune. I echo the poster above me about the MBC. Eliminate that and tune for your desired results with the N75. I can run to the limits of the MAP with it no problem. Unless you are working a small turbo like the K03 really hard, that should be good enough for most applications... |

I can exceeded and hold higher than map limit, turbo is roughly size of a gt28rs and I've seen no problem holding 25 to redline. There is all sorts of problems with the waste gate on these units which is why I chose the MBC over the n75.
I'll lower and smooth out ldrxn, but I thought the hierarchy of the ecu would follow kfmiop/irl if it never touched ldrxn values

F23 is not the size of a GT28RS.
Its bigger than a GT28R though.

BTW, anything you can do with an MBC, you should able to coax the LDRPID to doing, if you are under the MAP sensor limit. You may want to try the 5120 hack..
Also, please don't post excel files.

I anticipate that it should net gains especially with E85's ability to resist detonation. |

Yes, since the 1.8T flows like crap. |
