I used to get a lot of that lil knock that seemed random. Getting the maf trims dialed in as close to perfect as possible has taken all of that away for me tho. I would work on the maf trims

Same story here. Had some knock in the 3-4k area. Nothing uptop and knew I was still working the maf trims and had read that getting those dialed in could reduce knock, so I just continued on, pulled a degree or 2 of timing in the "trouble" areas and continued with the maf tuning. Seems to be gone now.Originally Posted by BackyardTurbo_FTW

How?
Getting the maf dialed in as close to perfect as possible allows you to run quite a bit more timing
Quick question, what are you all getting for fuel mileage just cruising? I am only seeing like 24-26mpg at 70mph, this is using the 'instant mpg' in the DIC. My LTFT's are -.8, and my STFT's are usually under 5. I know I could get the STFT's a bit better, but not by much.
That sounds about right for 70 on a flat road, maybe a pinch more. I'll look at the instantaneous MPG on Monday if I remember. I run a cruise lambda of .97 though catless, (closer to stoich for ~5.5 to 10% ethanol) so mine's prob a bit worse.
My avg dropped to 28.5 for the winter, used to be over 30 last summer. Winter blend & cold weather always drops it a few.

Yeah, I know the winter blend drops it, just seems like I should be getting about 28. Guess I should wait to let the weather stabilize before I really get worried about it.
Thanks!
same here at around 70mph, it shows about 26-28... and at 60 i see 32+

¿Are you talking about the Air Flow vs Frequency and MAF correction tables?
I just drove form Des Moines, IA -> Topeka, KS (270mi) and avg'd 27.6mpg according to the DIC. I reset he avg as I left my driveway. That was even with me romping on it a few times for good measure
My best avg was 29 flat, and honestly I think I had the wind at my back.
Wondering if anyone could help me (and maybe some others) in understanding the Timing tables here a little more... Most cars i have worked with before only had one timing table... and that made sense.... Here due to VVT we get 4 tables to juggle... So far i have just been making the same changes across the board to all 4 tables... But i realized that there seem to be some trends in cam timing that might allow us to better tune our timing for different situations....
Like for one, i noticed that in MOST of my logs, Part throttle acceleration seems to have both cams near maximum... heavy acceleration at WOT seem to have both cams about smack in the middle or sometimes a little nearer to minimum higher in the rpm range... with your foot off the gas, just coasting along boths cams drop to minumum..
These are just my observations... but if we knew a little more about when the cams do what and why... it would help us to better control our timing and use of the 4 tables to our advantage instead of just an annoying extra 3 steps we dont need.
Would be nice to know that we can dial in the max-max table for mild acceleration on the streets (like 10-30% throttle) and the min-min table could be nudged for a little better milage when coasting... and maybe the other 2 set ranges for other driving situations....
I for one think it would be nice to know when and why the VVT is doing what and why... that is just the way i am....
could have not said it better my self

At the first it tells to go to Max Airload Torque Table. Nowhere in hptuners can i find this, or is it called something different. The car is 2010 Saturn Sky 2.2 turbo
If it's a 2010 2.0L Sky Redline it should be under the same tabs as my 2007 2.0L Solstice GXP. Look under the Torque Management tab in the upper right and it should be under the General tab and labeled Max Airload Torque Table.
Majority of these tables can only be found with beta software, you have to contact support to get it.
Hey guys, would a MAP sensor leaking cause erratic AFRs?
Here's a screen shot.
Ok i have that screen but the Max Airload table is not showing.
Contact support for a recent beta build.
Also make sure you have your view settings on ADVANCED
