initial dyno comparison but I don't think its tuned right now judging form the dyno sheet and AF. About 10 whp gain and 7 foot pounds of torque from the numbers I caught. The pics are a bit big and the rpm range isn't the same between runs and the owner will be dynoing again after the ECM has had time to learn again.

Good work, a 10 HP gain on the dyno with out tuning for the mods is impressive.

It would have been interesting to see if there was any KR present during the runs.....

[SappySE107]

Yeah, tuning ability would be key. I am anxious to see how the dyno tuning goes with whoever does it.

[rsisbetter]

whats the "WCF" ?

[SappySE107]

with correction factor.

[rsisbetter]

does that mean tuning? er, self learning? must be a LATE model obdII thing?

[SappySE107]

Its need tuning, not "learning".

[leong6gtp]

oh yeah newbiestyle's ride. im also very interested to see what the numbers are after tuning.

WCF is weather correction factor....they try to factor in weather to give a more consistent idea of power output of X vehicle. That way all dynos that use this are corrected for Sea Level

[rsisbetter]

hmm, when i went to the dyno the other week, it said on the sheet: correction factor; 1.03. does that mean 1.0 is sea level, er?

[SappySE107]

from what I have been told, yes 1.0 would be 68 degrees F, 0 feet elevation and no humidity. 1.03 sounds reasonable considering I was told every point was a lot t (1.1). If you don't know the correction factor, then the dyno operator could have used a higher factor to make the engine seem more powerful than it really is.

well we save that for the mustang boys...lol
