I am scanning my 2009 Silverado 5.3 and the fuel trims are showing nothing. Any ideas on getting them to display a reading?

Thanks

Currently tuning a 2008 Silverado 5.3 with the 4l60e and 3.73's, I have removed TM and it is still a dog off the line. Any ideas?4402744028

Thank you Higgs!

How do you remove all engine TM on a 2014 Silverado? I am very familiar with doing it on the 99-06 Trucks but not so much on the newer ones. I have attached a copy of the stock tune.

pulled a stock tune off a 2014 Silverado, unlocked it with the credits, modified it then saved it. I am trying to flash it to the vehicle and it is saying something about an os id mis match. The guy...

I have a 2012 Silverado 6.2 (all stock except tires) I have been slowly working on tuning for a while now, I would like one of you pro's to check it out and let me know what you think. I am by no...

Thanks again!!!

Thanks I really appreciate the help. I have one more quick question, I noticed the denali has the 6.2 and i have the 6.0, can the timing tables be copied over?

Sounds good thanks

And here is a scan, im not sure if anyone is able to differentiate V4 or V8 by looking at the scan but the knock i was experiencing while low rpm cruising was in V4, I have since gone back and put...

Here is my current tune if it helps any

Thank you i appreciate it alot, the information you provided is exactly what im looking for.

Would the timing tables he posted be safe for an 09 6.0 L76 in a silverado?

From what i read the spark tables, maf and other types of adjustments can be made to yield more power. Is that not something i should do with this truck?

Like the ad says I want to buy a professional tune from a professional tuner, I do have hptuners software but i only have the knowledge to do very minor adjustments such as torque management, speed...

the code is for random misfire, the truck idles extremely rough and when you give it gas it puffs black smoke. anybody have any idea what it could be? i have attactched a log if it helps

Does anyone have good spark table (or a good baseline spark table) for an 09 L76? Preferably for 87 octane. Also when logging a WOT the scanner only shows around 83% on the TPS, is this normal or is...

I have a 2005 Silverado L33 5.3 all stock, I have done all the basics, such as torque management, adjust shift points, correct speedo, and i found a spark table on here that i copied over to mine....

Could you explain this first part a little more? I think my newer software is a little different, I have Eq Ratio vs. Rpm but there are not any percent values to change in it

I ended up scrapping the tune and starting fresh, I got a little trigger happy and changed too much stuff too quick. If you could just check that tune and maybe identify where exactly i messed up...

It is bone stock, I went out for a drive again to make sure it wasn't just a one time thing and it is still doing it. While just normally cruising around it just clunks and surges. It is definitely...

I just recently purchased my hptuners and I am trying to get it all figured out. So far I've only messed with the basics such as TQ management and shifting. I do believe the truck has been messed...
