So the think me and the cobalt car club i am in had some questions on was bolt ons and modding these new cars. if the ECU is supose to make the car run at 260hp every time and will adjust boost levels would that mean everytime u add and intake or some other kind of bolt on the car boost level will drop to keep you at 260hp? would i need to get HP tuners for the car right away or how would i be able to add hp with bolt ons?

 

you are right, ive been saying that for a while along with a bunch of other members. it will just cut boost. as of right now, hp tuners doesnt support the ss/tc. my guess is that since it will be only produced for a few months, the 09 will have a different computer leaving the 08 guys out to hang.

for a while at least, modding this car will not really do anything at all.

 

well it looks like they can save some money untill someone figures it out. it sucks that ecu does that and as soon as u hp tune there goes your warenty

 

...why does everyone thing HPT doesn't support the LNF?

VCM Suite 2.2.0 supports the LNF now

 

it's actually pretty cool that it does that.

and, the other way to look at it is, that the car has the potential for more power if you can crack the ECM

 

this was posted by bill@hptuners in response to him giving up on the hhr ss. was posted less than a month ago. pretty sure it's not the same computer that's in the cobalt/hhr vs. the solstice sky:

here's another post from someone on hptuners.com

that being said, yes, tuning is out for the 2.0 lnf. but, what computer are we talking about? can someone back up that the hhr ss is fully supported? where does it say it's the same computer?

 

That is the stupidest thing GM does was dumb crap why would you make a ECU do that if you are putting out a tuner car? Really don't make no sense what so ever. So there is no point of even buying this car if you plan to Mod it. Its just a waste of money. So this car is pretty much stock even if you but full bolt-on's on it will still only make 260? That's because of the ECU and you can't buy anything to crack that and GM is not going to sell a ECU where you can mod it. This is a joke. How do I contact the GM performance division?

 

...I said LNF, not FWD LNF

The HHR/TC guys are just going to have to limp along for a while

 

What??

 

GMPP is the reason they do it, GM wants to sell the power accessories for there cars. Hence the stage kits, exhausts, and intakes available from GM. It’s not that it can’t be cracked, it’s weather someone wants to put the effort into cracking it.

 

Do you think GM is going to come out with something?

 

HPT supports the Sky/Solstice LNF, but currently the HHR SS/Cobalt SS-TC aren’t fully supported

 

i've learned that gm makes these silly changes from year to year, it almost seems like they do it to make it harder to mod unless you go through gmpp like reign said. people will want more power, so if/when gm comes out with teh stage kits, if no one else cracks the computers you'll be forced to buy through them. money in their pocket.

 

true there

 

...For the SS/TC, ummm it's hard to say. Everyone gets conflicting answers from GMPP guys. The gentlemen I talked to in Chicago said GMPP was looking into stage kits, but wasn't sure that the tranny would still meet there reliability standards to cover under warranty with the increased power.

 

this is one of the big reasons why i think they won't come out with anything. can the tranny handle more power? probably. but it's rated for 258 and comes with 260 as it is. so from their point of view, if they did it, it probably won't be covered under warranty. but who knows. only time will tell.

 

yeah true but they should of made a tranny that could handle power over stock GM don't think sometimes

 

Its a manual, not an automatic, they usually have a higher torque ceiling than rated.

 

since the ss/tc cobalts dont;t exist yet, hopefully hhr ss guys get on top of this issue. we already have a member here posting about his tuned hhr ss getting 272whp. if he doesnt blow up his car then the tranny wirries will be all gone

 

yea sounds good man

 

the F23 is actually rated significantly higher then the F35

 

I thought it was only rated to 170 ft-lbs vs. 258 ft-lbs

F40 rated @ 295 ft-lbs is in the G6 hmm
