Well the wires and fuel filter came in today...but I live in the NYC area and the weather sucks. I probably won't get to find out until Saturday...hopefully the roads are dry enough to take the car...

Ok, I see. So I need to revert back to the STOCK tune and then follow something like CPIG's Tuning guide? When I load the stock tune into the car it is nowhere near driveable, won't idle, etc. I...

Hey guys...a couple issues that I need some help with. The car is as follows:

2001 Z06
LG G5X3
LG's "mail order" tune
LG Headers, full exhaust, no cats
OEM thermostat (for now)

At first...

hmmm i tried disabling the firewall for a minute and trying, but still nothing. i'm running Vista and IE.

I guess i'll try Firefox and see what happens.

I'm trying to upload a tune and log to a new thread...and it always times out during the upload. I've tried it multiple times, restarted the computer, etc.

Running Vista on a cable modem

Any...

sorry guys...but how about an '04 CV?

How can I use the scanner to help diagnose this?

Ok Bill I think understanding better now.

However, I don't need to re-license the file after every little change, right? I mean, I can make 1000 changes to the original file and SAVE AS every...

Thanks Bill... but I still don't understand something, though...

So, I read the file from the PCM (which in this case was LG Motorsports' file previously loaded into my PCM). Then I modified it...

Ok, so i've licensed my VCM Suite to my car. Can I download tunes from the repository and upload them to my car?

I have downloaded (from the repository) a stock tune for my car and when i try...

ok stupid question though...since i have 2 WBs (1 in each header) which should i log? does it make a difference? can i do BOTH?

thanks again for your help.

Yeah i have 2 AEM WBs actually...one in each bank. I wanted to scan the car first to see if anything shows up using the WB, just not sure what PIDs to monitor/what to log. Again I'm new to this so...

cool...i think i'll do that first thing in the morning.

At high load and high rpm, it's almost like a hesitiation or a misfire. starts at about 5600 -5700 rpm and lasts until rpm drops below...

hmm...ok.

I didn't mention it before, but the backfire is definitely coming from the tail pipes, if that makes any difference. As far as the pushrods/rockers go...what, just pull the covers off...

hmm...ok interesting. Best way to check? Pull them/clean them? Or is there a way to check with the HPT scanner?

thx for the quick reply btw!

Hello guys...

Never had an issue with the current set-up, but...

I developed a backfire this past weekend after a HARD, high RPM high speed run (toys for tots in Atlantic City run). ...

Anyone with this truck knows it suffers in fuel economy and sloppy shifts.

I originally bought my HP Tuners to tune my Z06, but now this Trailblazer I just bought needs some serious help. Does...

Awesome! thanks again for your time!

Peter

got it! one more question (PLEASE bear with me!), you mentioned HP/TQ numbers determining perfect A/F ratios. Is this determined ONLY with a dyno? I read alot on here that people have great...

thank you for taking the time George. That answered my question to the "t."

Is monitoring cylinder temperature and knock the best way to determine if you're running lean for your particular...

i see this is a common question

So I've heard alot about running lean can lead to catastrophic engine failure. Can someonme please explain why/how this occurs and what is considered "lean?" how does running lean break stuff? Does...

so i guess everyone else has the same questions huh?

hey guys...

i am very new to all of this. in fact i'm soooo overwhelmed at this point that i want to throw up and cry really. why do i feel like i want to jump off a bridge? :( i have read all...

thanks EC...i'll see how that works today!
