I don't have that option on mine. I do have the P010x DTCs under Engine Diag, but that didn't seem to work...but I suppose I could have done something wrong?

I haven't been able to find to safely tune my VE table because with the MAF disabled and/or unplugged the transmission switches to max line pressure. Is there a workaround or can HPTuners kindly fix...
I would imagine there are gains in larger TBs, MAFs, etc, until you start to see almost no vacuum at WOT. As long as you don't have some sort of losses or flat spots due to intake turbulence or just...
Holy blast from the past Batman! This thread was almost two years old!
Sorry to come off so hard on the issue...I figured as much, but I wanted to get up on a soap box for a minute. It doesn't help that I am still getting over the wonderful stomach bug that is going...
Ugh. That makes no sense. You can't make more power (horsepower?) at one setting and make more torque at another, at a specific RPM. Horsepower is based off torque. What that means is that the...
KR = Knock Retard.
To quote Pumpkin Escobar in Jay and Silent Bob Strikes Back..."I don't know what you just said, Little Kid, but you're special man, you reached out, and you touch a brother's heart."
Wouldn't that make the wideband O2 incorrect, and not the calculation?
Nice. I used to have a problem with Windows picking up updates, and they would finish while I was driving down the road and reboot my computer. After a few times I had to disable that stuff and set...
I think the general rule is increase until you get knock retard, then reduce by 2 degrees. I deleted EGR on my car, and was able to add almost all the timing back and then some without knock retard....
Shouldn't it recalculate for weather? Timing won't actually affect the AFR because you are calculating based on fuel and air flow...just the effectiveness of the burn will change, which would affect...
Was it a complete write? And have you tried to flash again?
I was bored again, so I wanted to see if air fuel ratio tuning was possible without a wideband O2 sensor. What I really need is someone with a wideband and some spare time to sanity check my...
That is a good write up (especially if I had a wideband o2 setup), but you don't cover the vs. time table. Are you saying to zero it out? Wouldn't you want different fueling in some circumstances...
Why would anyone add a time factor to PE vs RPM? Wouldn't that just lead to inconsistent WOT fueling? And wouldn't that just keep dumping progressively more fuel in?
Which leads me to my...
I could post it, but it won't do much good. I set the min EGR IAT to the max. EGR blips on sometimes.
One additional detail that I believe affects both formulas, they log 0 MPG when you go into fuel cut mode. But I don't really know how it would log infinity MPG...
So, it has taken me a while, but I think I have enough to work with to log MPG on my 3100 V6.
Here is the original V8 formula:...
Your screenshots are fascinating...can you send me the log file? So you haven't made any MAF changes, just the CAI (of course that is usually enough to make a big difference).
The EGR still blips on sometimes, but GM really wanted you to feel if you lost EGR. I run premium gas, but I have been able to toss some serious spark on the main spark table. 4-5 in most areas so...
I feel good about my garage from looking at your page. You seem to have the same tool spread as me...even the same tire pressure gauge, LOL!
Do you have a current scan, and can you tell me about...
I have the problem descibed in this thread:

on my 2003 Malibu. I don't suppose you could fix my file to prevent the...
I disabled EGR based on the IAT temp, but EGR still kicks in sometimes, usually at 0% throttle, sometimes 1-2%. Any thoughts on why this would happen? I am trying to figure out if there is some...
Just as the title says, I am curious how desired EGR is calculated. On my 03 Malibu, it loves to throw EGR into the engine, and I was wondering if this is based off some mystical calulcation like...
