i need community opinion about different approach i find. i call it double inverse model
the key is: no new routines and calls!
0. hw: plug MAP sensor instead of MAF
1. pterw:
-pterw_w / pterw is the some kind of tank pressures with DSTGRAD / DSTOFS routine perfectly fit for DSS path
-replace udst_w (pressure sensor) with uhfm_w
-replace signed to unsigned overflow checkings
-grad/ofs values should be set to make pter_w/pter same factor as other me7 pressures.
2. mlhfm: linear as the sensor curve are linear too
3. kfkhfm:
- axe replace rl -> pterw with respectively axe values from 250 hpa to 2550 hpa
- table values goes from 0.12 at idle to 1.8 at the high rpm to multiply MAP reading and simulate MAF sensor
- the values at the pterw axe are flat for now, to fix VE model probably
4. log pter_w vs ps_w and mlhfm_w vs msdk_w and fix kfkhfm smoothly <- im here
- the models looks promising, i see ps_w pretty close to sensor readings pter_w.
so the pros:
- pretty easy convertion, no need for new variables, rotuines etc
- LP filter already implemented
- hfm diagnose absolutely applicable here
- failback to alpha-n (hi Nye!) is here in case of sensor failure
cons:
- pter_w routine called from 1000ms raster. for now its irrelevant due to kfkhfm values are the same for all pterw readings but in case i want to fix that additional call should be placed somewhere
questions:
-should i cut mste (tev) from frloh_w calculation?
-sould i touch KFURL / KFPRG?
-what about DV, is it some kind of interventions i should worry about?
-what about all of this?
logs attached (its 5120 halved pressures)
Won’t work. Most of the things you need to do prj has already written. I made something similiar and using it with success for a long time now.
