Hi everyone, i have Alfa Romeo GT 1.9 JTD 150hp. i've been made a map for my car, i turn off my egr and put same tweeks on torque limiter, pressure limiter, injection time, Turbo boost.. etc..

i don't know how calculate the power and torque of this map, because i dont have mg/stroke in fuel quantity, i have torque,RPM..

As i know, EDC16 have diferent way to define injetion, is not mg/stroke.. how can i calculate the power and torque of this map?


Thank you.

If the 2d torque limiters are limiting power like they should be used, then you can do a simple conversion with nm and rpms to achive peak power etc.

ok, can you please show me the math? how can i do the calcs with Nm and RPM.
I use this maximum torque limiter on the picture?

anyway, for example, by default on original map @2000 RPM i had 355Nm of limit and in fact i had 305Nm@2000 RPM by Alfa Romeo specs.. (355-305= 50Nm of difference)

Now i have 443.5 Nm@2000RPM (more 25% of 355Nm), i can make direct calculation for the torque? 443.5Nm-50Nm= 393.5Nm@2000 RPM. its true? i'm sorry about this questions, i'm trying to understand.


This is my map.

Log injection qty and compare it with the map. For example 100mg means approx 500Nm

IQ x 4.96 = Nm

IQ x 4.96 = Nm

100 mm^3 = ~83 mg, this is correct?

This relations IQ is in mg? 
IQ x 4.96 = Nm is for JTD engine? because we have a different way to calculate on VAG engine i believe.

EDIT:
Something is not correct in this calculation.. if i use only the IQ i dont have right values for the original ecu file, and another thing, in my map i have 2% more of IQ. my ecu is EDC16C8.. 1.9 16v JTD engine

Thanks man

Density of diesel is 835 Kg/m3
which is 835,000,000 mg/m3
which is 0.835 mg/mm3

so 100 mm3 = 83.5 mg
