i did, but it really made the numbers look retarded. I dont know why. It was on a dynodynamics dyno, and since it's a load baring dyno i think that it may have messed up the numbers that ECU + gave me.
however when i got off the dyno and did a road run and collected data the dyno numbers were within 10 hp.

not even close for mine ..
granted mine is not your normal evo
but the point of the design was not in bragging rights .. it's in whether a tune works or not .. and you can see that by overlaying the various runs and do a comparison ..
cool thing is there's an SAE temperature correction factor for you to set a standard temp day .. http://wahiduddin.net/calc/calc_hp_abs.htm

Guys,
Usually a dyno will place a load of around 2000 lbs on the rollers (not positive on all types), so I'm not sure if the ECU+ has a place to enter car weight, but if you use 2000lbs, then the dyno numbers should match up much closer.
If you don't or aren't able to change this setting in ECU+, then the ECU+ will report dramatically higher numbers than the dyno.
