ok now a little more clear...but the sti blessed break and tell me how it works??it takes some program specifically, or you can also make it with ecm bo I don't know, never seen it done ... angel, I'm sorry, can you explain to me the best factor to trick the ecu??thanks
Then by brak you understand ke map type e and ke are the dimensions of the map if the last break of the map time inoezione corresponds to 80 mm3 l ecu will know ke unlocking the surge has already the calculated times until last brak that 80...now if you want to know ke you want to iniettarr 85 to update the last break to 85 and anke times ...if you want to inietyarr 85 without making it known to the eecu leaves the break and only touches the times calcolandoli and the ecu will always ke are 80 but in reality will be more
There are no fast cars... But only foot heavy!!!!:cool::cool:
ok now, or ideas a little more clear because I did a search on the break and I cleared the ideas!!anyway, I don't understand two things,from the various maps studied speaking of edc16 most, if not all, of the times, not exceeding 80 but they are always aware of why?then nesuuno that tap the map quantity of fuel injected as ever??
welcome to the quantity of fuel injected is not another ke map conversion ke passes the request of ccoppia or Nm in the diesel fuel injected or mm3 and then the map and calculated x 500 Nm or 100 mm3 until they exceed them has no sense of touch
There are no fast cars... But only foot heavy!!!!:cool::cool:
ok!!!clear!!!!!!!for example, if you make a map where the maximum iq and 80 mm3 you time them toccheresti a little bit?or leave them updated as a source??
I would leave them ori..

thanks Angel, you have been of great help!!!
The map and the injectors on the bench you do that by measuring the quantity? diesel fuel is injected (gauges FLOTRON) in mm3/colpo_cilindro for each ****llo rail pressure, at the change of the ET (time of arousal [us]), interpolating and then to have a map that tells you, for the rail pressure present, how many microseconds to excite the solenoid, to accomplish the volumetric flow rate that you need for each injection.
The logic part by the required torque - transformed in mg/colpo_cil required (total between all of the injections of the cycle - amount? pilot and post defined by maps, the relevant q Main control pair) - knowing P rail and the temperature of the diesel fuel (density? diesel) - enters the map the injectors with the mm3/colpo_cilindro you want, and the P-Rail current to determine the ET for each injection.
The introduction ? however, limited by the curve of introduction limit (EngPrt_qLim - for EDC17C49).
If you do not increase the introduction over the last break point of the map to the injectors, I will never have the time, in microseconds, ET al. Those times were measured and interpolated (even more than the introduction limit), then you are +or - of course that by energizing the solenoids for those of us in those Bars, you will have the introduction that you actually want.
hello checchi thanks to you x the contribution!
in this map there are limiters smoke; hence' threshold luminaire top and bottom as we think in these maps, and what is the difference between one and the other??
Hello Alfetta80, I'm sorry, but what kind of map are you talking about?
I know there is the map smoke SmkLim_rLamSmkEOM0_MAP (on EDC17C49) in which you calibrate the lambda minimal lower. In transient control of the torque goes up almost instantly the target of fuel to be injected, but the air arrives late (the compressor fails to give you the boost instantly) cos? to limit the opacity? of the exhaust gas (and stay within the limits of approval on particulate matter) you need to calibrate this map who controls the growth of introduction during the transients when the lambda reaches the minimum calibrated. Allowing you to give other diesel only after the arrival of the boost --> air. The lambda minimum when operating in a steady state ? much more? the bottom of the bed. The map smoke must intervene only in the transient. In steady-state the introduction should be limited only by the curve of introduction limit.
