recently i lost my hondata ecu reflash thanks to my dealership. dyno runs are expensive here for 4wd cars so i decided to keep track of changes in power with an app. i used to use dynolicious when i had the iphone and it was accurate. now with an android phone im using adyno. this one actually requires you to hold a gear and redline it. you input weight, drag coefficient, size, speed at 2500-6500rpm and etc. here is my result it is pretty darn close to a dyno i saw on acurazine while back: (plz note the graph rpm are 200 less than actual rpm due to bad calibration. so i added 200rpm to numbers below.)

209ft-lb torque at 4400rpm
177whp at 5900rpm

not sure what the spikes are about but im guessing the early peak in power at 4600rpm is a boost leak so ignore it. the software manual suggests awd auto vehicle has 27% drivetrain loss and 27% of 240hp is around 175hp. compared to my tl this is really rough in acceleration. you can see the power peaking again at 5700rpm and dying at 6300. being stock i managed a 14.71s @90.4mph 1/4 mile time and spanked a modded si. make sure you shift at 6500rpm first gear and 6000rpm 2nd gear. this was a second gear run.

now once i get the ecu reflash again i will do another dino at the same track and see the difference.

Very nice numbers, mine is completely stock and I have beat gs300's, TL's and G35 sedans with it to about 70mph. I am looking into getting the Hondata and the new downpipe and maybe break the 6 second 0-60 mark.

downpipe is probably the best mod after a reflash for the rdx. thr piping is very restrictive better get a high flow cat and the atlp catback. this should give you 15whp easy.
