power losses after remap etc

[dgannon69]

I was just having a quick read of the summarys from my remaps at Amd that i had done last year.

The 1st one i had done was on my 99 T-plate (DBW) 1.8T

and the second on my 02 plate (NDBW) 1.8T

both are A3's etc.

Anyway the DBW after a remap produced 191bhp and the NDBW produced 195bhp.

anyway while reading the summarys for both tests i've got the following figures which i can't quite get my head around...

anyway while reading the summarys for both tests i've got the following figures which i can't quite get my head around...
NDBW 1st
Power at Flywheel (corrected)
194.4 bhp

Power at Flywheel (measured)
190.5 bhp
POWER LOSS 43.4BHP

DBW
Power at Flywheel (corrected)
191.6 bhp

Power at Flywheel (measured)
181.9 bhp
POWER LOSS 32.3BHP


So what i can't understand is that if the NDBW is producing better figures how come its losing more through the transmission? does the DBW have a better response etc or could it be because the DBW was older and more run in?

P.S power at the wheels for the NDBW is 147bhp and 149bhp for the DBW.

Anyway if you can make any sense of my babbling please let me know what you guys think?

Cheers
Dave

Did you have the same set of wheels for both cars during the remaps?

 

[dgannon69]

yes both standard 5 spoke alloys everything on the cars remained the same. I did wonder if the aircon was left on in the NDBW car as they are made to run with it on...

 

[jojo]

Wouldn't be the compressor, this switches off when you give the car full throttle. /ubbthreads/images/graemlins/laugh.gif

think you've got the DBW/NDBW wrong way rounf. 99 model would be an AGU cable throttl;e 1.8T, where as 02 1.8T would be DBW AUM.

Ignore the corrected figures...Look at the whp figures. They are around the right figure!

ok mate cheers.
