Visualizza Versione Completa : edc16u1 - limitazione gasolio e turbo oltre la soglia impostata dall'ecu
salve ragazzi, come da titolo, vorrei superare i limiti imposti dalla ecu, utilizzando i bits fuori driver. (Nel senso che superata una certa soglia, anche aumentanto i limitatori e bits classici gasolio e turbo, queste ecu vanno in protezione)
Allego una mappa ori come esempio
grazie
A quanto vuoi arrivare non capisco. Queste auto se sai come toccarle vanno davvero forte senza fare cose strane

Devo andare oltre.... ho gi? moddato mappe del 1.9 cc. da oltre 350 nm con motore stok, ma devo preparare una turba pi? grossa per superare 2,5 bar reali ed ovviamente il gasolio gli deve stare dietro.
Hai queste informazioni sui bits?
Grazie
ragazzi riformulo... Sapete il limitatore AFR su questa ecu dove si trova??
Hello
3 lambda map start at DFEC0.

Aumentando la lambda aumento il gasolio ed automaticamente aumento il turbo... dar? ancora maggiori problemi con la limitazione. Spiega meglio, grazie
You need to lower lambda values to allow injecting more diesel.

se abbasso i valori lambda, smagrisco il motore e si rompe... altre soluzioni?

le mappe lambda nel motore diesel non smagriscono come nel benzina, sono usate come limitatore di fumosit? quindi se capisce cosa contengono le tabelle puoi aumentare la portata di gasolio ovviamente adeguando tutto il resto lambda 1 nel diesel equivale ad avere un afr di 14,5 per questo l'utente ti dice di decrementare le mappe

ma non capisco cosa c'entrano le mappe lamda con la limitazione...se puoi essere pi? preciso

At 4000 rpm and 1000 mg/hub of MAF you can see 1.589 value of lambda.
1.589x14.5 is an AFR of 23.0405.
1000/23.0405=43.402 mg/inj of fuel allowed.

Mi stai dicendo che ? un problema di rapporto stechiometrico? Se la miscela ? magra posso capire che possa andare in protezione. Ma in questo caso abbiamo una miscelta grassa e quindi non capisco cosa vuoi dire. Puoi spiegarmi il perch? di questo tuo ragionamento?
There is no problem with stoichiometric ratio.
I was telling how to calculate fuel limitation.
Diesel engines run lean. For example 23.0405 AFR, this is lean.
If you want more fuel with the same air mass, then you need to run richer.
How much air mass is your engine running at 4000 rpm?
Have you done any datalogging?

I did not do the log data . I can tell you that the damage affecting the 1:58 bar overpressure and limp home!...
and now I can not read the values because the car is no longer in my hands
how did you solve it?
Hello
I am understanding that you have 2 problems: Overboost and IQ limiter.
For overboost you need to modify turbo and vnt maps.
For IQ limitation you need to modify lambda maps.
Try to open vnt vhen overboost. And do not request too much boost at low rpm.

maps turbo are ok . How do I change the lamda to prevent the recovery data from maps iq ?

For opening vnt must decrease the value?
For opening vnt must decrease the value?
what criteria should be used to decrease the lamda according to iq ?
For maps turbo , I put the original values and goes into overboost ... because the pressure rises because of the same maps iq .
Yes, For opening vnt you must decrease the value.
If you have overboost with original file, then could be stuck vanes.
For example, AFR target of 17:1 without smoke.
If you put 2100 mbar at 4000 rpm, you are near 915 mg/hub of air.
915/17=53,8 mg IQ
You change lambda from 1,589 to 1,172 to allow that IQ.

You change lambda from 1,589 to 1,172 to allow that IQ.
With my setup at 4000 rpm I map iq 8200 mmg ( equivalent to an increase of 2563 points ) , while on the lambda always at 4000 rpm we have values 1589 points ( original because I have not yet touched the lambda ) . The car does not smoke so much ... but I do fault what have explained above .would you do me the proportion who say so in practice ? So I understand better .
Thank You
?In which map have you put 8200? ?Driwer wish, torque limiter or NM to IQ conversion map?
Well, 8200 should be 82 mg of IQ, factor:0,01.

Well, 8200 should be 82 mg of IQ, factor:0,01.
a when Increased map qi a 8200 AFTER the Maps Lamda , I make the cut ... let me Calculation More explicit and not directly the result Surrounding final . you were talking about this map iq or for which the ratio afr ? Street Address? Thank You
Let?s make another example.
In TL at DDF04 you request 314 Nm at 4000 rpm in the last row.
From NM to IQ map at E0796, 314 Nm need 53,9 mg IQ at 4000 rpm.
In Lambda at DFEC0 you can see 1,589 at 4000 rpm supposing MAF=1000 mg/hub
But 1000/1,589/14,5 = 43,4 mg IQ allowed and you want 53,9 mg IQ.
Then lambda should be 1000/53,9/14,5 = 1,279
Of course, Driwer wish values need to be higher than TL values.

Excuse me , but do not understand where you find the value of 53.9 mg on the map IQ E0796. I Checked a 4000 rpm Values Are Different ! thanks
The amount on the map turbo where you find her ? You could write the addresses and mg iq you say ? I'm having trouble following you with values
E0796: NM to IQ
factor 0,01 and precision 1. Then you see mg.
EC378: turbo
factor 1. Then you see mbar.
But MAF is mass air flow. You need to calculate from boost.
