Bad image? :iono:

I'll see if I can get something better

Heres mine, even though I don't want to post it :(

Mods:
-Visconti pump gas tune
-SRT header back exhaust with high flow cat

As I mentioned at PAS, I'm pretty sure the issue is related to my missing snorkel. The car doesn't feel like a 157whp car though.

I just noticed in the videos of your car it looks like there's some kind of smoke coming out of the exhaust. Is that water, or something to be concerned about?

There's mine. Ignore run 3, that was from when I was there in October. Same mods both times, just different revisions of Visconti's tune.

Mods:

Nameless Performance Overpipe/Downpipe/Highflow cat w/ resonator and Axle-Back (Original style, non-offset, 4" mufflers)
Visconti E85 Tune
K&N Panel Filter

Yep, I noticed it as well. When I installed the exhaust, I noticed more soot on the back bumper. I figured it was just the high flow cat, but Mike has a hfc too and didn't blow as much smoke as mine. I noticed some smoke from the other cars as well, but it looks like water. The smoke from my car looked black, so Im wondering if Im running rich. The O2 that PAS used was placed only on one exhaust outlet, so the gasses ran through two cats. I may very well have been running rich too.

I'm installing my AFR gauge this evening, so I'll see what the readings are from a wideband before the cats.

Edit - Does the smoke look black to you, or white/gray?

looks grayish, checked the original video and it looks like the smoke starts around 6500 RPM

Yep, definitely high RPM. I recently had to fill my coolant overflow tank. Im hoping its not a head gasket, I don't want the to have the dealer rip apart my engine.

Ill be sending a sample to Blackstone really soon, fingers crossed that its not coolant - but thats where the signs are pointing.

That sucks man. Hopefully it's nothing serious.

@civicdrvr

If you're running super rich I could see why you seem to be down on power.

Grayish smoke is usually oil....and white like you said is usually coolant from a leaking headgasket...I hope its not either...

It is really hard to tell what color the smoke truly is on the videos from the way the light is shining at the back of you car from the outside...

[QUOTE=wdninja;911475]Here's mine:


Your a/f looks good compared to mine. I'm going to have to do some data logging tomorrow and see what's screwing it up. Something is up, my torque in the dip is lower than what you're car is showing.

Yea, the videos aren't helping due to the lighting conditions. But, I topped off my coolant overflow tank on Thursday. I stopped right below the max line. Today, ~200 miles later, its half way between min and max.

You can see the smoke much better in xjohnx's video of my car (the one vtmike posted). I have an appointment at the dealer on Wednesday. I'll tell them what I've experienced and hopefully they'll do a leak down test.

You putting your exhaust back to stock before taking it in? Might be a good idea.

Sent from my SCH-I535 using Tapatalk 2

Nope, they would need to prove that the exhaust would somehow cause the head gasket to fail (if thats the issue).

Hopefully it's something minor and doesn't come to that. Many cases even though the proof is supposed to be on the dealer it comes back on the owner because they know most people don't have the resources and time to fight it in court.

Here's mine - running way too rich up top or it would probably make more power
AEM Intake
Unichip
FA20CLUB EL Catted Header http://i271.photobucket.com/albums/j...ps18ba8333.jpg

Yea, looks good till 6k.

but this is still very impressive, no torque dip in comparison to the other two plots, as much HP s the E85 tune above. I am impressed Real world dyno confirmig that headers + tune add 20 HP and cure the torque dip. Very encouraging.

Have you sent John any logs? I don't see you losing 20+ whp because of the snorkel. I made 180whp on a dynojet with his 93tune and AFE intake only.

This dyno had some strange results. Xjohnx car has made 180whp on e85 with overpipe downpipe combo, with axleback which seems really low. My car was 171whp with downpipe, axleback, inlet tube, and filter. Both seem on the low side. Then wdninja car made 167 with just an axleback and it's an auto which seems high for the setup.

Yea, I thought all of the dyno's seemed a bit off. Your tourque dip looks strangely low in the valley too. Hmmm...

Yeah my a/f was super rich during the dip (off the chart.) I'm going to do some data logging with torque today to see if I can figure out the issue. My car wasn't fully worm when they started the dyno as you can see how it's picking up power with each pull. I'm thinking it might be from me removing the large resonator attached to the air box or possibly a dirty maf from my oiled filter.

I have, and he said it looks good. Right now, I'm thinking there might be an underlying
issue (head gasket), which I have an appointment on Wednesday for the dealer to take a look at.

Yea, the results were odd, but their dyno reads low. There was a Boss 302 that put down 388, most have been putting down 410-420 stock.

Sent from my Nexus 4

Probably stand to lose HP if you change anything about the stock intake besides the filter.

What gear were the pulls in? Auto the same gear?

Runs were done in 4th, as far as I know the auto was done in 4th too not sure though. Perrin intake hose isn't supposed to hurt anything. I've seen conflicting opinions on the large resonator. This might have convinced me to pick up the TRD intake.

The results are puzzling, although consistent. I put down almost the same #'s on an earlier revision of this e85 tune back in October.

Both times I had just reflashed from pump to e85 the night prior to dynoing though. I'm guessing with some more time for the ecu to relearn the power will pick back up. Maybe I'll redyno in a couple weeks.

The only other thing that I could see potentially being an issue is that I forgot to disable TCS, which apparently can cause some interesting results on the rollers.

That would make since. (410/388)x(most of our results) comes out to be more in line with what I was expecting. The outlier is wdninja's car which could be a factory freak and your results which might indicate a head gasket (hopefully not though.

My traction control was on too.

Is the unichip tune specific to the header or the intake? Do you think the torque dip elimination is due to the header? It's good to finally see a 3rd party dyno which shows the dip basically eliminated. Not the highest peak torque but definitely the car I'd rather drive. Clean up the top end and you'd be at 185 WHP or so.

Yes the unichip map is for my intake with "headers" so not specific to my headers but the parameters have more to do with the intake side. The headers are definitely the culprit of removing the torque dip.

I did some logs with torque today for a/f ratios during the dip at wot. The results were for 12.1653614 for the time I was at wot throughout the rev range.

Are the measurements pretty reliable using torque for this? I think it's supposed to use the factory wide band o2 sensor but it's weird that it measures that same exact value the entire time at full throttle with no fluctuation.

I get the same reading from torque/oem 02 sensor. I'm wondering if they only read in a certain range.

Also, it seems like the numbers are down about 5% compared to the other dyno numbers I've come across with same/similar setups to the cars there. It will be nice to get the raw files and change some of the corrections to see how they read/look.

That's interesting. Have any of you guys with Ecutek been able to log a/f ratios richer than the 12.1 value.

Sent from my Nexus 7 using Tapatalk HD

I believe the OEM A/F sensor isn't a true wideband.

so when can i expect your order ;)

Also your Dyno was on SAE that might explain your lower numbers vs the rest of us who use STD correction

13:1 post catalytics is not super rich. Even if it were 12:1 pre cat that is still not super rich. NA best power is going to be between 12.8 and 13.2 but it should not be black smoke rich at 12:1.. more like 10:1.
