Some factors to consider even on the same dyno on the same day ! which have nuffing to do with dyno settings !!

Bonet open or closed
Age of spark plugs
Engine compression
humidity
Fuel temp
Fuel pressure
Fuel Octane ( octane of fuel decreases as it gets hot / cold fuel return from the engine )
Engine knock retard
Amount of exhaust gas's in the air
Water temp
Oil temp
Engine temp
Intake temp
Tire pressure
Tire temp
How tight the car is or is not tied down to the dyno
Heat of the dyno rollers
Amount of people watching / standing around stoping air flow
and the list goes on..and on !!

Then you have all the calibration factors and settings within the dyno !
Only when you know how to use a dyno / understate how it works will you understand dyno figures mean bugger all !

Everything u say is true!
However, we're still looking at the data obtained from the same dyno on the same day.
So, even if we make allowances for all the variables u listed, the car equipped with sophisticated ECU should deliver significantly more power that similarly modified car without it. Don't u agree? Maybe the mods didn't go far enough for Hondata to "kick in"?

Another observation - the case for keeping DC2R stock is getting stronger.

Pitty - no stock DC5R on the day. Judging by DC2R results, it could make a very interesting reading.

Thanks to Tinkerbell for submiting these results! When's the next dyno day? Anything planned in Mel?
