    He did not clip the wire on an ign coil, that's why he couldnt get rpm or torque. They compliment each other.. so yea. But I will still get it for you.

    Those second set of graphs you have posted appear to have blatant learned timing correction in the end of the curve. DO it right the first time and have the tuner calibrate it on a load bearing dyno for best results. No flash tune/street tune stuff unless you want a 85% result.
    Well my tune on the dyno shows 14+ AFR very lean. MY wideband says 12.7. I need to retune, and log my stuff. The tuner just sent me the most basic conservative file for my mods. I need to pay some more and have him look over my logs and retune for timing etc.

    IIRC his motor is a $#@! to setup for torque/rpm pickup for an older dynojet 242, so i assume thats why it was horsepower over MPH.
    I think this is why he couldnt do it.

    I eat a dyno wideband once a month, it probably was dead or in your exhaust flap or something.

    in exhaust widebands are much more important, 12.7 is still lean.

    The thing that is really odd about that is that horse power is work done over time, a mathematical function of torque. Very weird to accurately get horsepower w/o having torque.

    Lean for FI. But ideal for NA-12.7

    It may say something about how you and I spend our free time differently.

    You and I seem to spend our time similarly according to facebook. Asian women, Alcohol, BMWs, Forums. LOL.

    Everything you said is true, except for the Asian women part!

    Here is the basic formula Tq=(5252 x HP)/ RPM. I don't have my rpm at the given hp rating. I would need to get my rpm to mph or something..

    Right dude... You are right, this IS the formula for HP.

    The thing is - this drum (that you are moving) weighs a certain amount. This drum is accelerated both momentarily (torque) and accelerated period (horsepower). This is OVERLY simplified - but is the basic gist. You are making this drum move faster and faster, over a period of time (RPM/SPEED) - to get a good high peak horsepower - you need to make either a decent amount of torque at high RPM, or a TON of torque at medium/low RPM. My point is this, you cannot derive horsepower without knowing how HARD you moved that drum (i.e. torque) - and then how HARD you are moving it throughout the RPM band (this is a horsepower curve oversimplified). Not sure if this is making sense - but this website may help out:

    http://www.nsxprime.com/FAQ/Miscella...queHPSpeed.htm

    I could explain this over voice better than over "message" - but it holds true that this computer that has provided the graph MUST know force/torque before giving you horsepower over time/speed/RPM/etc.

    Hope that makes some sense.

    Someone finally said it Click here to enlarge That is how the dynojet works.

    Yeaaaa...that is the formula for torque...which IS the inverse of the formula for hp.

    So by definition (simplified):

    Torque is the twisting force applied.
    Horse power is work done (i.e. torque) per unit of time (i.e. rpm)

    Thank you...This is what i was trying to get at w/o going all out, glad someone understood what i was trying to say.

    I did the math for myself as I did previoiusly with my gti...

    in 4ht gear @ 70 mph my rpm is at 3200 where my hp is at around 210... so

    210x 5252 all over 3200= 344.6 wheel tq.
