e20 observation .. more HP but little TQ gains? why?

[lamrith]

NP, I would like to know the difference between the two actually.  One obviously is flywheel, but what is the other one and how does it relate....?

From this wordy jaunt ..  http://www2.egr.uh.edu/~mece2hv/Papers/4.pdf

Brake TQ = TQ at the Brakes/wheels.  So some loss is assumed and calculated.
Flywheel TQ = would be more of a estimation of a Engine Dyno.

Interesting.  I always heard "Brake HP" used reference to Engine dyno's and figured that brake Tq was similar and had to do with power at the crankshaft.  But then the other being Flywheel makes me wonder.
I have Engine Brake Tq displayed on my SCTx4(using as a live display until I get OBD2MX and Torque going)  I have seen it showing 600 when I am driving with "youthful exuberance".  The numbers I see would agree that it is more crank based as there is no way I am throwing 600 to wheels...  Much as I might dream/want that to be true..

I will reconfig the display and have both showing for the drive home and do some comparisons and let you all know later tonight.

Cool,  i was given a SCT support ticket number so I am hopeful they will be able to open it up on my handheld.  I will let you know and we can compare.

@Lamrith was that in Nm for your 600 reading ?   That would be 442ftlb converted if it was ...

I do not recall it listing a unit of measure at all.  but I will check tonight.

Make sure you are  using livelink 2.8.0.5 i think thats the latest.

I would validate all items and look for anything that says torque at flywheel or etc flywheel torque maybe and make sure the dmr tab is pushed so you see all the dmr items

Yup,  my SCT does not list any DMRs if I hit the DMR button .. I am a bit more hopeful however as I did get a pretty positive response email and a ticket number.

It will likely need to a update to the tuner .. well see.

Based on how direct memory access controllers work, I am not 100% but I think to get the handheld to read the specific memory address in the ECU standalone (without a laptop) it will require a firmware update to the SCT handheld itself to read the live/raw data. 

I may be wrong .. hell this late in the day I might bet on it.  well have to see.  i am excited either way..

There is one in NM and one in lb-ft

ENGINE TORQUE FLYWHEEL is in lb-ft

TORQUE AT FLYWHEEL is in NM.

DMRs are in all caps and don't show up on my DMR tab, they are mixed with everything.
