Said that, if you do not have the right amount of fuel, you do not have the turbo, there is a second map in the rail pressure that suppose is for the fuel cut when the fuel is hot, but I think I'm wrong, this map work with less amount of mm3 of fuel and work with the map reading and then with the altitude now if what happen in your video come only when the engine is warm, I think is a rail pressur problem, I live at 1500 mt and I can read -0,1 -0,2 bar in the boost at idle, the cut in the load you have posted can be the shift moment ? when the engine is warm the ECU adapt the injection in base of the MAP reading, changing timing. early I think we do not have much fuel, said that you must know the MAP managment in the ECU, control the open loop. Let me know the reading of the map at 6500ft at engine of and at idle ,with my scan tool I have read the boost control actuator is at 85% at idle, is the vnt actuator and during testing the actuator I can put it at 95%, now I have not tried to increase the turbo at idle and I do not think if we can do somthing, normally I start to modify the turbo map at 1000 rpm. If you need the right address let me know, we have the most important map for make it fly. Rail pressure threshold / temp.I think is related when the fuel temp go high. like a pop off or wastegate.working on the egr but it's limit the presure in the intake manifold. There is another limiter at 2250 after that, is kpa limiter is twoĬorrection of fuel quantity Rpm x map. įCV map, the two hump for the EGR Hysteresis and the map from the egr. If you scroll the map starting from the gas pedal or "driver wish" you find after that, torque requested at cold engine, torque requsted in standard condition. Wooowww, yes winols is the best, but need more experience, in ECM you can not modify the driver, is not an original sw, for what I know 43 point is one degree in the timing map, but I do not touch this map happily
Hopefully I can take some of those lessons and apply them here.īack to the files to start doing some comparisons to figure out what maps are what. I've done a fair bit of mapping/calibration work, but that was with the benefit of a lab and a dyno. Unfortunately I don't have as much time as I would like.
#DIY ECU FLASHING HOW TO#
If I can start to ID maps and edit the driver in ECM ti(or figure out how to use win ols better) I can start messing with this. I'm just trying to wrap my head around which maps are what. Yes I see the axis, winols does a decent job at finding the maps, I'm just not sure which are which. that is adjusted on other map that manage the map sensor and rpm and then ,after she have the right quantity, go in the rail pressure map find at right rpm and quantity needed, the right pressure and go in the injector map for opening time, this map have rail pressure and quantity for the axis and then she know how many time the injector stay open and go in the timing advance for know when they open ok the ecu need to know how many mm3 need for this torque at this rpm. always.a number like 16 and 16.is a 16x16 map, this instruction is for the ecu for doing the right job for help in the logic of the ecu, think like an ecu, example Rpm x mm3 of fuel and the z axis is the rail pressure Ī littel bit secret, first of every map, you see two "break point" this break point is the axis for the map, x the first Y the second and early a value for the bitĮxample, if you go at the rail pressure, at this address 0FB5A0, you see two "tips" early the rail map, this tips are : The 15500 value is the map for the FCV.do not trust in the definition ,the value you see is g/s, you must look at the two hump that start at 0E1F1C, look at mine 811 and see what have do with this two hump.
