im using this for calculation
http://nefariousmotorsports.com/forum/index.php?topic=1371.0title=

KRKTE = 50.2624 * Vh / Qstat

Vh: Displacement of a cylinder in dmˆ3
Qstat:  Valve correction for petrol/n-Heptane (g/min)

density of n-heptane is 0.684g/cc

Qstat = 715 cc/min x 0.684 g/cc = 489.06 g/min
1.781 dm^3 engine
4 cylinders

KRKTE = 50.2624*(1.781/4)/489.06 = 0.0456

therefore KRKTE = 0.0456 ms/%


Have here the formula found,what is that "Valve correction for petrol/n-Heptane (g/min)"
Heptone ?Is that pressure?
Thanks in advance

Method 1:

starting from this:
original flow of stock injectors with stock fuel pressure: 317cc/min
original KRKTE: 0,10301

calculate like this:
KRKTE * FLOW = CHEATNUMBER
0,10301 * 317cc = 32,65417

CHEATNUMBER / new FLOW = new KRKTE
32,65417 / 630cc = 0,0518

just change your krkte and the flow of your stock injectors (car should have 3bar)

---------------------------------------------------

Method 2:

new KRKTE = 50,2624 * volume of one cylinder / qstat of injector
qstat is calculated with 630cc * 0,684g/cc = ~431
50,2624 * 0,44525 / 431 = 0,0519

as you see, both times same outcome
remember to check the stock injectors part number to get the right flow

dont know if this is your car but this 190ps A4 does have 317cc@3bar

and please dont use siemens deka....

50,2624 is fix! You have to accept

You can read here http://nefariousmotorsports.com/forum/index.php?topic=935.msg8024#msg8024

But its given Nummer for your calculation. No Need to Change this.
Thats what i meant to say.

Thanks, now it works:-)


lg.

Just add .020 to your pump gas KRKTE.

That's usually dead on.
