Calculating Instantaneous Net Power

[dbaxter_ss]

M6/2k1/SS Vert
In this run 4.226 second from 42-83 according to efi I went digging through the logs I have on my laptop here and cant find any 0-60 runs :(, i will dig through some to see what I can find.
all the mods are on my site at http://www.2001camaross.com
just goto the mods link.

Just had to post a new best from today - VERY HAPPY
391hp using my calc from above for accuracy: 3554 (SS Vert ) gm.fuelrem and dx at 12. Heck even dx at 6 it was at 385

40-80 in 3.8 seconds SWEET!!!

no 0-60 number because its an on ramp and I have to cross an intersection first.

He he he... Power rules...!!!!

Can I get a copy of your PID you set up? Did you change the sae_generic file or place it in the cal_pids file?
Thanks,
Bill

Is this PID in 7.2.3? I see the old one but not the new one mentioned in this thread.

Derrick has the power formula dialled in pretty good. 8) 8) 8)

Can you copy the cal_pid file you are using? I am not sure about the format.
Thanks,

THese should work for you
GTO
CTS-V
Z06
and
Vert SS

Just replace the 185 in the calcs below with your own weight.

I have the dx for 2, 6 and 12 then look at all three. the more pids you log the lower the dx. I usually look at all three. If you logging a bunch and do a 0-60, 2 will give the correct amount, but 12 will look like 100hp. Vice versa if you logging just a few things and do a 0-60, 2 will give 500hp when 12 shows 350.

I can tell you that using the Z06 12 dx below, on the mustang dyno it pulled 322, on the street we pulled 327 so its pretty darn close, better ITS REAL, everything that affects TRUE HP is truely affecting your output. So anything slowing down VSS like FRICTION, Aerodynmic which NO DYNO can see will affect EFI since its logging the change in speed from each logged amount.

Thanks for the info. I will give it a try. After a big meal I am also about 185...
What are these for:
CALC.LTAVG F601 CLC-00-980 % Fuel "Long Term Average"
CALC.STAVG F611 CLC-00-979 % Fuel "Short Term Term Average"
