So I had this done back in August when it was about 98 degrees outside.

Sorry if its bad quality, I didnt have a scanner here and just found it while going through my file cabinent so snapped it with the digi cam.

I put down 174hp and 125tq.

Look ok to you guys?

It looks like a stock dyno ...... :)

post it up in the Dyno sticky thread

the a/f doesn't look like a stock graph.

which gear was this pull done in?

?

looks like the sensor was not connected ....

wouldn't that lead to no reading?

you don't need afr to calculate hp/tq.

the graph looks like a standard rx8 NA dyno chart. Not high end, not low end. Just looks typical.

I understand that. I was just noticing that ~15:1 afrs shouldn't be right and I can't remember the AFR's being that flat on a stock plot.

The power plot looks typical.

i'd say it's impossible for the stock pcm in this car to be that lean in open loop.

Yeah, that AFR reading is not coming from the car.
That said, having the probe sitting in open air should have read at least 22:1.
Weird.

How sad is it that a perfectly normal, stock dyno plot for an RX-8 yields 174 HP and 125 tq? :icon_no2:

Why does the power and torque dip at two points? One is at around 6300 RPMs.

becuz thats when some of the port opens.

First dip is the SSV opening. The second is the APV.
Kinda sad that a power adder takes away power first.
I'd call that crappy tuning, but there is really nothing you can do about it with just fuel and spark.
Since Mazda has a stepper motor on the APV, they should have it open gradually.

Kinda sad that a power added take away power first.

agreed - but according to THIS (http://www.youtube.com/watch?v=oHg5SJYRHA0) Mazda already considered that .

you're an ass! :lol2:

Damn!

I'm pretty careful about clicking on links to YouTube stuff.
You need to spoof the addy.
