ECM map values

Postby ex250 » Sun Nov 22, 2020 2:25 pm

Hello, i'm trying to learn something almost in ECM titanium, it's more user friendly and perhaps better for beginners, but there is one thing that I can't understand, what are the values used on the maps, I don't know what I'm changing on a map, no units are present.

Any one knows what are the units used on the maps?

well, I suppose that:

Injection at part throttle table is rpm/load, and the figures are mm3 of injection? there are in x100 multiples? so a 7860 value would be 78,60mm3?

Rail Pressure supposed to be bars not? figures are x10 so a 13500 should be 1350bar

Injection at part throttle map 1 (boost x rpm) I don't know what they are and why the lower range at 700rpm are higher than at 4500rpm...

Same with the part throttle map 2 (boost x rpm)

Phase of injection seems (by the read along forum) that is egr, max value is 9393 at top range, so If I fill all the values with that number, the EGR would be closed all time... ??

Turbo pressure has two identical maps, no diferences on them, I suppose they are the abosulte pressure readings, max value is 2190 perhaps milibars not?

Overboost, I dont know what units are used here, there are 2 maps too, max value is set to 8500 at low rpm. about the half value at high rpm 4200...

Torque limitter, also dont know the units used...
