Stage 3 med17.5.21 1.4tsi help redducing load

Postby haddumex » Mon Feb 24, 2020 3:44 am

Hey guys, tuning a Hybrid turbo 2014 seat leon 1.4tsi, making 215whp already at 19.5psi peak and steady 18-7psi at high altitude (Mexico city 11.2psi baro, 780hpa) however the car Will reduce the specified boost and specified load at high rpm as you can see in the logs, deviating from the requested load on KFMIRL, i can't see any obvious limiting factor that i havent modified yet, Pressure ratio is higher, KFMIRL should request around 180-190 constant load at my set MDMAXNMOT, SVBL is higher but for some reason requested boost Will start at ~2200hpa absolute request and the drop steadily down till redline,instead of holding requested boost/load, i'm clearly missing something here, but just cant seem to find what exactly. Willing to pay for help, attached are Ori and mod file

No overboost, AFR are perfectly in check, pressure ratio limiters are higher for high altitudes and not limiting it, HPFP are perfectly in check, its a Barometric pressure/altitude correction map, tuned these engines dozens of times but this particular car at high altitude its limiting load

maybe

25AFAC - KFPVTMSV - Map pressure ratio over turbine
25B050 - KFPVTMSVFE - Map pressure ratio over turbine - high dynamics (for filling gathering)

also mutiplex info from 272A98 and Tra_trqMaxGear from 2743B0

Tra_trqMaxGear has been modified in another revision of the file, no change at all. unfortunately, Will try the Pressure ratio uber turbine, was just looking at them, but i believe theyre not influenced by altitude and they dont limit load directly, but i could be wrong. Seems to be a map that reduces load for component protection at altitude (maybe).

Thanks, Jurebv
