help with air fuel ratio dynograph

[Captainstr8edge]

The dotted line is 13:1, certainly not where I would want my supercharged car to be...

The tuner is supposed to set it i believe, but yes, that is still too lean. I was speaking in general terms.

I'm no expert, but that AFR line looks like complete and utter shit.

I read this and busted out laughing !!!!

Anyway, as for your graph... was this a tail-pipe sniffer? do you have a bung installed for the wide band o2 sensor?

and yes, the data does NOT look right.

I'd be tempted to get a scope and peek at the pistons.

Remove those cats ASAP and get a new tuner. I'm repeating what everyone else already said, but those A/F numbers are garbage and the clogged cats are going to nuke your engine.

They used the tail pipe a/f clamp. And now I think the cats may have been bad at the time of the Dyno. Looks like I will be doing a little gutting tomorrow.

im going to play devils advocate and say it looks good to me

OK guys, Saturday morning I removed the cats just to find that there.isn't anything in there. It doesn't even look like some gutted them. Its just a hollow pipe. Are the slp cats like this?

 

[Captainstr8edge]

They are probably fake cats then. Post pics.

I am curious as to who is doing the tune. If you don't want to out them on the forum please PM me. Mostly because mine was tuned in SC too.

 

[07BlownFoose]

The car was originally tuned in NC but I had it ran on a Dyno at a tuning shop in sc. The Dyno run was when the Guy told me everything looked good.

I will be taking the car to pro Dyno in fort mill SC for new tune and spark plug change before the tune. Price as of now with me buying the plugs and taking them to pro Dyno is $570 turn key out the door.

Hmm... the other guy that was in SC hasn't recently moved to NC has he?

Anyway, Pro-dyno is awesome. Dan and his crew are really cool. My car was on his dyno for nearly 4 hours on Monday before we got it all figured out. I was sort of hesitant because of the price but it was totally worth it.

Just watch out for Bad Bad Leroy Brown.. LOL. Which is the shop Bulldog.

No he has been in sc for a long time.
Yea it's expensive but I have been told by everyone that it is well worth it. So I'm going to give it a shot.

Ok. I tried to work with Amazon at first and was not happy. So I ponied up the $$ and went to see Dan.

 

[07BlownFoose]

They have a good Rep and that's what I need at this point. A REAL tune. LOL

 

[ctt326]

It seems like more and more of this tooning has been going on lately.

 

[Jeffk]

When are you going to see Dan?

 

[07BlownFoose]

I will probably go around the end of the month.
