"no lift shift" manual ?

[transampimp]

Has anyone heard about this yet? The new HHR SS and SS Cobalts are going to have it. I was told you just keep the gas pedal down to the floor, and shift. I've done this in my T/A but you have to keep the revs down, and its a killer on the clutch. I think its cool that these cars are built for it. Anyone know how it works? I'm so glad I didn't buy that supercharged Cobalt a few years back. I'm test driving the turbo one the day it comes out.

with electronic throttle, they can just electronically close the throttle to PREVENT you from doing a REAL powershift.. its quite easy to do with their PCM capability and electronic throttles..

this is mainly a safeguard

Although there are many "safeguards" programmed into the bosch engine controller.. heck if you put a K&N airfliter on you will make slightly more power for a short time untill the controller corrects itself... and your back to factory power rating. This LNF Turbo PCM is nothing to sneeze at.. its far more complex than the supercharged LSJ's P12 controller. The P12 controller is much easier to change via HP tuners... i dont think they have the LNF box cracked yet?

so thats all it is... i was completely confused by this "feature" that actually sounds like BS now. thanks for the info dan.

They made it sound like it kept the engine near the rev limiter keeping the turbo spooled. That would suck if the throttle closed. I hope its easy to tune these cars once they come out. I bet 300+ horsepower would be a breeze with a few upgrades.

i would much rather have a C6's setup with the 6 speed paddle shifters

actually i was thinking about installing BMW's sequential gearbox technology. its much better

[transampimp]

Is that a true manual or an auto?

[Superman09]

the c6? Its a 6 speed auto, paddle shift... with automatic override option i believe

I won't have to lift this year. Faceplated T56 FTW. but its gonna be noisey

To keep an engine at a certain RPM (say right near redline) the load on the engine MUST be EQUAL to the power being produced... there is no way around this.. its a Force balance equation.

Just think about it, if you want your car at redline rpm while in neutral.. you only need a low % of throttle opening.. While racing in this cobalt, As soon as you tap the clutch or pull the lever (im unsure which sensor they are using) the electronic throttle will close to the % that is required to keep it at that rpm.

I would be willing to bet that it will make people more consistant and probably a little quicker... but its NOT powershifting as we currently know it..

Even in my supercharged cobalt, the actual throttle position does not match what my pedal position is, sometimes. They apply some PID controls as well as extra "damping" to slow the throttle opening compared to what your foot is actually doing.

i understood it entirely, i was just saying it doesnt sound like something id want.... id rather be in control of whats going on is all

I dont even think you would need to be trying to powershift to notice a softer effect with that, as normally I punch the gas again just a split second before I let the clutch out
