yeah I know i'm running rich as hell lol...

imma talk to Ion, and see what we can do, cuz from the last tune, i went richer when i should have gone leaner

anyways here it is....
266rwhp/304rwtq AFR: 10.1 =-O=-O=-O

mods:

Both cats taken out
Ion tuning
KN intake
Bosch cheap plugs
Cutout
160 thermo
automatic btw

I guess with bringing the AFR to about 13 i'll be around 280rwhp and 320rwtq

 

You live in Davie, Florida? There was a high school prank show on MTV the other day with one of the locations being Davie.

 

THREAD HIJACKER!!!

no, but i'm very close (about 20 mins)

 

Those numbers look about right for the few mods u have. I doubt that you will gain 14HP and 16 ft/lb of TQ from leaning it up, but you never know. Those are about the same numbers that I made with no tune and 15:1-15.8:1 A/F ratio above 3000 RPM.

 

Emir,
there has to be something wrong with the dyno. I definetely leaned it out the AFR and it has to be right around 13 right now, considering your gains....


Nice numbers!

Ion's back! Woot! I'll need to contact you soon about some work.

very odd...

if i had more $$$ i'd get it dynoed at a more reputable place... :P

there was a jetta before me, and he seemed to get the AFR right

 

I'm just guessing, but if you had the cutout open and they had the a/f tube up the tail pipe, can that make the a/f read incorrect? Oh, and I would go to kelly chevrolet, they gave me a dyno sheet of 100rpm incriments of hp/torque and a/f, which tells you exactly where your a/f is.

 

You could probably gain 15HP by richening it up to 13.0:1, just as he will easilly pick up that kind of gain. Just leaning out the stock programming 11.7:1 target A/F ratio is worth 15HP. Going from 10:1->13.0:1 should produce even more gain. Why would you even dyno it a 15.8:1? Could do serious damage. Is it possible they put the wide-band after the cats

Seal:

I'd also be concerned by those dips between 5,100-5,200rpm.

 

Injuneer, before I dynoed the car, I had no idea that I was running lean. It goes from 12.85:1 AF @ 3000 RPM steadily climbing up to about 15.6:1 @ 4600 RPM and spiking up and down there after in .1:1 increments. The wideband was put in the cutout. There were many other f-bodies being dynoed at the same time also.
Here are the Dyno Files, which can be viewed with DynoJet RunViewer

Run 1 (cold engine cutout closed)
Run 2 (engine warmer, cutout still closed)
Run 3 (cutout opened wideband placed in cutout)
Run 4 (same day, new fuel filter, cold engine, cutout still open)

Set the smoothing bar at the top of the RunViewer to 0 to see the dips in the charts.

Don't mean to hijack
