did anybody notice his o2 sensor was way lean maybe that is why he had a lot on knock .

Just a few things,
Knock on stock pistons will break ring lands off. I don't know how much it takes, but it does happen. The convention is on a stock motor, do not let it knock. Granted, it's the same for all engines. But I suppose what is considered knock changes.... I mean a random count here and there will probably never be a problem, but if it's consistently hitting multiple counts during a pull, I'd be taking some timing out.
I have let mine knock some, but I'm looking for an on the edge tune.
Finally, just because you beat those cars doesn't mean dick. Obviously those are good running cars, but they are not low 12's cars unless they have a good driver and a prepped surface. That is the beauty of our cars, they make good use of the power in marginal conditions, until you make big power.
I've only seen one run 10's and it was worked on pretty heavily.
It is ok to think that the tune is fine mainly because you feel that there is some success with it but I would say 50% of the cars that come in with John Doe tunes make more power when I remove timing from some point in the tune. It is absolutely pointless to leave the timing that high if the knock sensor just pulls it back...
We have went low 10s on a 16g and 9s in a stock frame charger. 400whp would get you into the 10s if you could drive it. Just my 2 cents.
Make sure you mention that you did this in a 2500lb tin can....
I will make sure to inform you that this car weighed 2850... The other cars that went this fast around between 1900-2300(FWD tin cans) but I am sure the next comment you will make is about it being on methanol so the argument will continue. Tyler's car is running a factory steel hood, hatch, power windows, working headlights, 2 seats, factory dash, full cage, 15 gallon fuel cell, ect, ect....
Its funny that everyone bashes Tyler's accomplishments but everyone jumps on Curt Browns dick when we goes mid 10s on a 16g...
How do you change airflow in link from grams/sec to lbs/min??
I would really like to change my settings to see what im actually flowing. I did some math and showed my 20g (16g converted to a 20g by justin) was flowing 42 lbs/min (not saying my math was right but used common sense with math to convert it over) and that was spiking 26psi and then settling to 24ish due to a stock 1g unmodded BOV
My logs in link show HP at 503 and tq at 389 through my auto in 2nd gear @7k rpm with 17* peak timing on 91 octane all with My1gDSM tuning my car to the limit on a VERY aggressive tune, thanks again!! (btw my emails havent been going though to you for the last 3 days)... She was running great and dusting all the new 5.0 track package mustangs at the drag strip with it taking 1.1 seconds for the auto to shift by the time I make it through the traps (while running 12.81@107)... now looks like I have to pull the motor & trans to fix my tcase output shaft seal on the tranny side :/ unless someone knows how to change that seal with the motor and converter still in the car?
We have went low 10s on a 16g and 9s in a stock frame charger. 400whp would get you into the 10s if you could drive it. Just my 2 cents.
How have you gone so fast?? That's very impressive. It seems like only a few people break 11s on a 16g .
What 16g are you running? What intake mani?
I wasn't bashing it at all, I just don't think it's fair to make it seem like you guys bolted some parts on a car right off the street and went that fast, when it was a prepared racecar.
I wonder how fast my car would be if it lost 500lbs.... My turbo's probably way smaller than your 9 second stock frame turbo.
I'm not a fan of Curt either.
So your first post was to say that it wasn't our tuning ability that made the car fast, and it was because it was a tin can. We tell you the car is heavy and now you say we acted like we just threw something together and it was fast? I have never said it was easy, thats where our experience in tuning comes from, hours of R&D, Trial and error.. that was why he posted how fast our car went, not because it was easy or because it was light, its because we spend hours trying things that sometimes work to get an end result. FWIW I street drive it all the time, only time it was trailered to a track was shootout.
2850bs, automatic, qtp's. You only need to go about 120mph to get a 10.99 in a well setup car.
Lol, it's not tuning ability that makes it fast, it's the selection of parts, and the weight. I'd expect anyone who builds a high compression methanol motor in a lighter car to go fast. There's only one combination of numbers you can put in the ecu and make best power, and you don't need to be a magician to find it, especially with a dyno.
To me it seems saying
"We have went low 10s on a 16g and 9s in a stock frame charger. 400whp would get you into the 10s if you could drive it. Just my 2 cents."
Tends to imply you waved your magic tuning fingers over a basic 16g car and it went 10's
There's a big difference between doing that in a race car, or a full weight 5 speed with street tires.
Maybe when you talk about your accomplishments, this statement should come out instead
"We have went low 10s on a 16g and 9s in a stock frame charger in our AUTOMATIC RACECAR. 400whp would get you into the 10s, in a race car if you could drive it. Just my 2 cents."
Lol, and don't ever lecture me on hours of R&D, or trial and error.
I appreciate all of the comments and any helpful information. I've got work tomorrow so I'm settling down for the night.
I'll attempt to tune out all of the knock tomorrow and get another couple of pulls.
Only one AWD dyno in my area and I don't really trust them so much.
I have the AEM UEGO wideband but it's just not currently hardwired into my ECM. No time for it lately. The o2 sensor you see if the stock one in the front. My wideband is set into my downpipe just behind where the oil pan sits.
Thank you for the advice. I'll definitely look into it. Speed density is in the future but I have very limited funds right now.
bastarddsm does kinda make a point. I just looked up that forward facing 16g car and it is a STRAIGHT race car.
I know the place and agree although you can use their dyno and tune yourself.
How do you figure?
