Bosch EDC16 REMAP | Torque/Power Calculation

by **goncaloasantos** » Thu Dec 11, 2014 6:35 pm

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..

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.

Or i use this map to calculate the real torque and power? i'm a little bit lost.

The second map looks like torque limiter in Nm.
With the first map (Nm to IQ converter) you get mm3/hub.

are y sure nm2mm3 and not 2mg?

Yes, in Opel is mm3.

torque calculation....injection qty*1.5*no of cylinders

No way... Example. I get 78mg/hub in my 3.0 tdi, but it's impossible to get ( 78*1,5*6 cyl.)= 702 Nm. I never measured my car on dyno, but i think it has below 600 Nm.

TQ = (IQ * 6 * Cyl. Number) / 4 * correction factor

For 6 cyl. engine the factor starts from 0.9 and folds to 0.8 at high rpm
For any other combination, the factor is from 0.75 at high rpm to 1 below 2250 rpm. To simplify calculations you can use factor 0.9

So, for 78mg on a 4 cyl engine you`ll get ~420Nm or 631 Nm on a 6 cyl engine.

And Power, in BHP can be calculated like (TQ * RPM) / 7121
