Did anyone check CED's website? Update on the solstice kit is 550.00 and they have pics of the parts and such.

 

also, people are seeing crazy gains with JUST a tune, the problem is you lose your warrant, i'm sorry but if I have the GM kit and a catted downpipe yet dyno 10-15whp less than your Hahn or HPtuner tuned car with an OR downpipe, I really won't be all that upset, knowing I still have a warranty...

 

Nice find. But why wouldnt this work for the Cobalt SS/TC's as is? Is the intake that supposedly will be included in ours really going to make a difference?

 

correct the charge psi sensor will see 255kg when 22.5 psi is reached. the fuel tables all happen to end exactly at 225kg so by going to 23psi you have just gone into a zone where there are absolutely no values, thus the computer will disregard the psi sensors input and go into limp home mode, it must see over 225kg for 3 sec before limp home mode is activated.

the only way to get arround this i am told, is put a clamp on the signal back to the ecm for the map sensor. by lowering voltage back you can then run whatever psi you wish, ex: 26psi and you will not exceed the end of the table @ 225kg, although the downside to this "clamping" is the whole fuel table is thrown off and must be tuned appropriately. its time consuming.

by getting the stage kit not only do you get the upgraded psi sensors but by factory only you get a extended fuel table file via download and flash, and that alone is what holds us back from making the higher numbers, so yes as explained you can get around this but the gm kit will not only look better but also reduce headaches in the long run.

for more on map clamping i would suggest posting on hptuners forums. and please dont bring your attitude to the hpt forums, everyone there is very nice and most of the time willing to help with the whatever is causing you trouble.

finally, another intellegent person

 

"*Warranty is void if kit is used for racing"

Guess they're referring to if you get caught racing by the police.

 

ive tuned a few lsj's
i own a lnf but when i get to tuning that i will be screwed haha
i dont know anything about tuning it specifiacally like hpt tables and that stuff
i will push to understand it though

correction to previous descriptive post, table maxes out at 255kpa

 

I think tuning a LNF is easier than a LSJ, so you shouldn't have a problem if you've tuned LSJ's before

 

hmm really, yeah now im doing my cuz's 05 ss/sc 60lbers w/ 2.8, dual bypass, all the goodies haha injectors were a bitch to get idling

 

Tuning the lnf is easy as pie, theres no stupid ve tables to worry about at all.
Clamping the two map sensors should work in theory and shouldn't be any harder to tune at all since the maf is reporting the correct airflow, the pressure in those sensors doesn't really matter.

 

Drag racing at a track is still racing.

 

So is running through the gears on the street basically racing? Is going wide open throttle racing? Its such a broad term...

 

Your warranty is not there to sponsor anyone on this site.

If you are THAT worried about you warranty


drive like you care.

 

If racing to them is wide open throttle then everyones warranty is void as soon as they want to see if the GM tune did anything, lol.

 

denying coverage to me for racing to me is otherwise they can talk to my lawyer
A: caught by police racing
B: having your car towed from a race track or dragstrip cause you blew somethin up.
C: not wiping the numbers off your back windshield when you complain about your LSD not working anymore

but yes if you run your car at a track NLSing all the time, you really cant expect warranty coverage, but i believe that spirited backroad driving shouldnt make equipment fail.

 

what is the afr range for the lnf?
the lsj runs beautiful around 11.3-11.5 safe
11.5-11.7 ***** on the wall

i just need to know what i have to aim for
i figured out the boost controll under the desired air load section
i need to set the afr to to good spot and then timing is easy and i will be hurting a little on cams lol dont know squat on adjusting those.

 

sometimes 12.5

 

that lnf or lsj i have heard ours love to pig rich like total soot cannon

 

14.0 from 2000rpm that gradually dips to 12.8 at 5320 rpm.

 

listen to the man!

 

Soot does not mean rich man.

LNF runs lean compared to most cars, and it soots.

 

whats the best afr ?

 

All direct-injection engine's are sooty. Even Mazda's and BMW's.

 

Will launch control be changed in any way with this kit?
