EFI RWHP and EFI RWTQ

Hey Guys
A LOOOOONG time ago I had enhanced the HP calc pid in this thread
http://forum.efilive.com/showthread.php?t=3&page=5
Calculating Instantaneous Net Power

I am on a local musclecar forum ( http://www.musclecar-evolution.com/forums ) and thanks to one of the guys during a heated HP thread the equasion was posted for torque. Having that I figured why not create a calc pid for that also. ( thx skeeveman for the equasion info )

I get so many people asking about a HP number and where it came from, and I only use EFI, no reason to hit a dyno, I have this and a wb02 ( lc1 from greenlight motorsports ) why waste the money to get a number from a dyno when I have everything here.

so on with the new pid.
The formula given was for torque based on hp numbers below
====================
hp=(tq*rpm)/5252
hp*5252=tq*rpm
(hp*5252)/rpm = tq
====================


What I had used for HP in my calc back then:

OLD
*CLC-00-989
hp 0.0 400.0 .0 "(((3554+({GM.FUELREM}*6.350)+185)*{SAE.VSS.mp h})* dx({SAE.VSS.mph},6))/8226.63"

CALC.SSHPTRUE6 F60A CLC-00-989 "kW,hp" Performance "SS TRUE HP 06"

But to make it more accurate name: "(car) EFI RWHP Smoothing Factor 6"
Something that can be added, instead of 3554 ( using the customer vehicle weigh pid ), the 185 is the driver weight
NEW
*CLC-00-989
hp 0.0 400.0 .0 "(((3554+({GM.FUELREM}*6.350)+185)*{SAE.VSS.mp h})* dx({SAE.VSS.mph},6))/8226.63"

CALC.SSEFIRWHP6 F60A CLC-00-989 "kW,hp" Performance "SS EFI RWHP Smoothing Factor 6"

There are the smoothing factors for 2, 6, 12 depending just like a dyno on the change in polling.

Now for Torque: Change the 9XX to your favorite pid #.

*CLC-00-9XX
hp 0.0 400.0 .0 "(CALC.SSEFIRWHP6*5252)/SAE.RPM"

CALC.SSEFIRWTQ6 F60A CLC-00-9XX "kW,hp" Performance "EFI RWTQ Smoothing Factor 6"

In the end you have a nice rolling dyno giving you EFI HP and TQ numbers.

Its the dawn of a new day, forget Dyno RWHP and RWTQ
Go with EFI RWHP and RWTQ
