no you are exactly right, this toolbag doesn't even know his own car. LOL. The car is going to make the same power no matter where it is cause the gay ass ecu. So his 14.0@101 run is probably exactly what he'll run in NY depending on his launch there.

 

hey so um, did you not see my post. You made a challenge, you said that's all you cared about on here... so stop being a dick to people, man up, and let's run when you get to NY. We shall do it at E-town in NJ, that is all
/thread

 

hahah, this guy hasn't proven a damn thing and he doesn't even know about his own car. haha, what douche. Dyno was FAKE, track numbers show those of a good driver in a stockish tc, not bone stock though, remember he has a filter and muffler delete. lol. 275whp and 300wtq my ass though, I trap 103 on street tires with only 222whp and 201wtq. I trap 100 on slicks. what a ******* liar. GTFO these forums loser.

 

You guys are too funny. Why doesn't someone do the mather here and try to figure out how much HP it takes one to run a 14.0 @ 101 at 8,200' elevation? I can tell you this, the stock 260HP isn't getting you anywhere close. You are looking at closer to 15s.

Since cobaltss.net is so smart and says the ECU limits and maintains power @ 260. Please tell me how it does this. I have some engineering experience and reading that posted link tole me NOTHING about how the ECU even measures TQ let alone keeps it @ 260 regardless of conditions or mods. I challege you to enlighten me.

@ What elevation?

 

omg you fail at life.. seriously GTFO...

260 hp is closer to 15's? so explain to me how all the ss/sc's with 200-225 hp stock are running mid to low 14's explain how a stock 2.4 with 160 whp ran a 14.9, and most of all explain how ralliartist with 222whp ran a ******* 13.5 explain why you can get the grasp around the fact that elevation doesn't matter with this car..

seriously just gtfo..... from the words of GM / chevy themselves at the GM owners meet in e-town... when trying to boast about the new ss/tc they said that no matter altitude the car would always push enough power to get 260 hp... so that way you dont feel your losing something buying it in canada.. god you're ******* dense..

 

RJ its spelled out for you the LNF engine limits the hp and tq. whats not to get?

 

pwned! and why does it take more power to run 14's at higher elevation? It doesn't *******.

At higher altitudes you LOSE power because of the thinner air. So MOST cars have to retune. But the SS/TC's ECU automatically adjusts for 260, so no matter the altitude, it will make that much power, which explains this guys 14.0@101. Now an SS/SC would definitely run 15's stock cause the thinner air would kill the power output down into the 160-170whp range and the car is hard to launch as it is.

 

If you have 'engineering experience' you should be able to come up with a simple algorithm to estimate torque. What would you use for inputs?

 

Please explain to me how it does this? What is it basing TQ off of? What engine perameters does it use? Is there some kind of dyno in the wheel hubs? What measurements is this ECU using to even determin engine TQ? Please educate me. I would love to know how this system works.

Sorry, I figured you would be intelegent enough to know I meant sealevel equivelant HP.

I do know. I want to know if YOU or anyone on here does and can tellme how it does so.

 

I understand that a given car would make more power after being retuned at sea level than at 8000ft. But the ss/tc always produces 260.

I can't tell you how, cause I didn't design the damn car and I think that it's bullshit that it does that anyway. one of the two reasons I don't like the LNF, the other reason is DI.

 

Do I know the specific algorithm? No, I don't work for Bosch and they likely created it.

I do know what inputs would be likely necessary to come up with a torque estimation.

 

gee, that explans a lot. Tell me Mr. ecotec wizzard. HOW does the ECU and the LNF measure TQ?

What are they?

 

same way the tq managemend works in any other gm car pretty much, calculated engine load, tq load etc. don't know the exacts, but it does use the wastegate and pulling timing to reduce power output when these parameters are exceeded. Hence why a car in NY would probably be running @15-16psi at a basically sea level elevation, where as a car at a higher elevation will run @20psi to make the same power.

 

Hmmm, gettin a little warm, but doesn't tell me how the engine measures load. Common guys, you can do better than that.

 

LOL you serious? any one with a dash hawk or scan gauge can tell you the ecu knows how to measure load.

 

So tell me then, smarty pants. How so? How acurate is it? and how doest it use load to compute engine TQ?

 

data streams:

air data (MAF/IAT)
fuel data (injection qty & timing)
MAP
RPM
Coolant Temp
O2 sensor

don't think any more are needed to get an accurate estimate, might be able to cut a few out, lose some accuracy, but wouldn't tax the ECM as much

 

your losing this argument pretty quickly and the right side is actuallly starting to show proof of why there right.

 

Forgetting a few major ones here, but getting better.

that still doesn't explain ****! You come in here bashing yet can add nothing intelegent or technical to this argument what so ever. Common quit dodging the question and tell me HOW this engine and ECU or any engine and ECU would even attempt to hold engine TQ @260.

This is too funny because all you fools still fail to realize what I am even getting at here. One person had it here and noone even noticed. That's the problem with this board, all of you (OK most) are too busy bashing and name slinging and can't even realize what's going on. That is why you suck. Because you are too petty and ignorant and uneducated to even try to learn something and attack skeptism with thoughtfull analysis. doesn't it make you feel soo much better to hate on someone. Doesn't it give your insignificant lives more meaning if you are better or your car is better than someon elses? yeah it feels good doesn't it guys. the biggest obsticle to your knowledge groth are your hard heads. You all should try to grow up someday.

 

if you already know, then why are you asking?

 

no I'm not, you should be able to estimate torque with the above variables

 

No one knows the answer, this thread is full of idiots. The guy is lying but no one is willing to take him up on his offer besides paul that has 400 horsepower and even if he did make those numbers on the dyno he would still loose to anyways.

 

Dear Mr. Troll,

Engine torque models have been around for over a decade, if you really want to see how long do a patent search. There are a gross multitude of methods for estimating torque and for controlling torque. If you don't believe me google.com/patents will provide you with all the evidence needed. This engine uses torque management and is seen in accurate dyno graphs.

Please shut the **** up now Mr. Troll.

Sincerely,

Krispy

 

You left out 2 essential values for which TQ can not be calculated without. That my friend is a FACT!

 

Which are?

further proof the LNF is torque limited



Torque is a flat line in a steady state dyno test, limited at 260.
