Did you mill the head at all and you're just not telling?

Are you using a Windows machine? Have the dyno up on screen, press "print screen" on your keyboard, open Paint, and then select "paste" from the Edit menu. You will then be able to save the image as a jpeg.

no, it's a pic of the dyno computer screen, I don't have it on my computer.. I do have a print out, I'll try to get it scanned

1. USDM H22 (2000 model year)
2. Fujitsubo Accord EuroR header
3. Generic hi-flo catalytic convertor
4. Tanabe Racing Medalion
5. JDM TypeS air chamber intake
6. 17x7 Volk GT-N wheels with 215/40/17 Yokohama Parada Spec2 tires
7. Apexi V-AFC that was hardly tuned (See explanation later)
8. Exedy full face organic clutch (you'll see why I mention this later)
9. Quaife ATB (probably irrelevant but hey it's attached to the tranny)

That graph shows 2nd, 3rd and 4th gears. About 178-179 hp.

Conditions

1. About 70° F ambient temperature
2. Humidity was probably about 40%
3. I think it was a Clayton dyno
4. A wideband O2 sensor was used in place of my stock unit
5. A Motec PLM was used to measure the air/fuel ratio (Connected to aforementioned wideband O2 sensor)
6. The stock O2 sensor was still connected to the harness but left dangling off to the side
7. After the VERY first run the driver said my clutch was starting to slip
8. After the VERY first run I got a CEL and it remained through the session

Note: That red line in the graph shows a run where the driver gave up due to the clutch slipping more and more.
Had the clutch not been purportedly slipping they would've had more time to tune the V-AFC. (I can't make the clutch slip...strange) We stopped because we wanted to make sure I could get home alright.

Kind of sucks that I did this "handicapped"

Ray you could have the worst dip at VTEC crossover I've ever seen. How are you getting a 50+ hp dip at the crossover? There HAS to be something I'm missing there correct?

I think that's the shifting NOT VTEC crossover. Gears 2, 3 and 4 are on there....get it?

Ahhh, when they did my car they brought it into 4th and then floored it from 2500 RPMs.

Thats so wierd, why'd they do it like that. It makes it so hard to tell where you should take fuel out...there's no rpm axis on the graph... i guess you could do hand calculations but...why?
Did u get any torque #'s.
Did u get a cel because you took out the oem o2 sensor? Wouldn't a cel cause you to go into limp mode?
I really think the type s intake is hindering your performance.

There are other graphs (and numbers) available but I didn't get them....why bother when we ended early.
I think the cel does cause you to go into limp mode but I'm not 100% sure.
I think the TypeS intake is perfectly fine until a better chance at a dyno is had.

i've since smoothed out that crossover dip in a/f and power.

Care to back that up with something solid? I think your Mugen exhuast is really hindering your performance.
