Mike, im not sure anyone has figure this stuff out yet outside of car developers (and chris). I mean this isnt normal speed density tuning with one VE table, this is a matrix of VE tables that all interlock.
good luck with the cams, I've got my money on stand-by for dec 1st =]

Normally, most cars have the ablity to remove thier MAF sensor and run the car in open loop (open loop is ignoring your O2 sensor), this is called speed density, or SD for short. To tune in SD, you would normally use your primary VE table combined with your wideband's results in the scanner (or using long term fuel trims, LTFT). this is an extremely simple process. The idea is that your in full control of your car's fueling, very helpful for turbo charging, altho you lose the computer's ablity to tune itself.
Now back to what Chris is explaining, instead of our cars having a "simple" primary VE table, we actually have two "phases" mixed with different maf and rpm zones. this isnt something that can be graphed in a two dimensional table, like everything else is in HP tuners. However if you scroll to the bottom of the thread you'll see that someone has made a 3d graph in excel to simulate what the VE table would look like.
Where to start tuning? I'm stuck at work right now, but im going to see tonight =]
Where i'll begin is exactly how the one guy did on the thread. Start with recreating a 3D VE table to see what im working with...
Has anyone actually started on this track yet?

Bigworm,Im buying my hp credits from a member and using the software from a 2.0,this member was telling me that the tune/dyno shop can do this because the two basically share the same peramiters,but may take a little longer though, can you shed some light on this for me??/

if i understand you correctly they want to take the OS from the 2.0L and put it on your G5?! You'll have a huge paperweight when thier done. Not to mention theres NO reason at all to do this, the 2.4L's OS is more then enough to get high levels of preformance. The OS shouldn't be used, nor should the tables be copied over. They are completely different.
I've not dyno'd yet, i have an exhaust leak that is holding me back, but its safe to assume i've picked up at least 10-12hp from just simple spark and fuel tuning. I highly suggest finding someone else that will tune your car... or pick up hp tuners and a wideband yourself.

i wouldn't run cams without a tune...you can do it, you would just be alot better off with a tune.

the stuff im refering to in the new update deals with replacing the MAF.

but it would be nice if he'd dyno with the stock tune, i think that would give a better understanding to the rest of us of how the cams change things from stock. then a second run with it tuned...

ok mike CHECK THIS OUT the HHR guys fight more then anything alot of us stay away from their site because a supporting vendor only comes in talks down about ANY thing we bring up that he does not carry we usually tell people to come here for the real deal. BUT YES i am telling them and YES there are HHR's out there that want in on these up and coming cams but you will start finding more HHR' owners here =)

think of hp tuners as the modern day distrubtor and flow valves... thats all it is, except much more powerful and acurate. i might write a 2.4 specific intro, but really more interested in comparing notes with other 2.4 guys before i start posting a how-to... doesnt seem to be many 2.4L guys using hp tuners tho =/
