Title: MDFAW -> MDBG Post by: masterj on March 29, 2013, 02:46:49 PM Guys, I can't understend what protects this "limiter" subfunction. Can anyone chime in and help me understand why do we need MDBG? From what I understood so far it is there to protect engine from very high Nm increase, but can't be sure without your confirmation ;)
Also what conditions has to be fullfiled for this limiter to activate? So far it looks like it is always on (SY_CVT = 1 && B_mgbget = 1)... Im I correct? B_mgbget is always 1 unless mdgbeg == 0 || mdgbeg == FF. If I translated german correctly then mdgbeg is increase in Nm/s, so it will never be 0 Nm. Upper limit is 2540 which is very unlikely to get :o So B_mgbget = 1, right? Right? KFMIFABG is never used because of SY_CVT = 1 && B_mgbget = 1, correct? (sorry, I am unable to completely understand "if" conditional statements in FR. So /1/ means true? /2/ = false?) And final question: If KFMIFABG isn't used then mifabg_w = MIN from mivbeb_w AND miistoar_w + mdgrad_w * 10?? But miistoar_w + mdgrad_w * 10 seems to send pretty high numbers... Atleast in my file mdgrad_w can be between 0% and 635% (mdgbeg / MDNORM * 100). MDNORM by defualt is 400 Nm..
