I worked to get the MAF dialed in after going back to 91 octane and switched over to VE this evening trying to fix that table.....below are my logs. The first one is logging MAF and then i switched...

I'm learning myself, but it does look to me similar to the knock I'm having on a 5.3 truck after a rebuild. I have the knock sensors set to stock currently, and every time i step on the pedal with...

I was actually thinking I might have been more worried about it than I should, appreciate the info!



Yea that's actually the stock timing table. I had toyed with the timing a bit, increasing...

Have an 07 Sierra that was just rebuilt that I'm trying to get dialed it. Heads have been ported, stage 2 truck cam, cold air and long tubes. Considerable milling done on the head and block during...

Will give that a shot. Thanks!

Trying to get my truck tuned up to where I can at least drive it when needed, will be a bit before I make it in for a dyno tune. Stage 2 cam, rebuilt bottom end, stock heads with a valve job. Motor...

Well it's definitely plugged in...i even swapped o2 sensors with one of the rears that arent being used any more and it acts exactly the same way. Most likely a ground then. i can think of one...

Just put a new cam in a 2007 5.3 LH6, new lifters, valvetrain, etc. My 02 reading on bank 1 gradually decreases as the motor runs....can somebody let me know what exactly is going on? :shrug: I...

Sounds pretty cut and dry...Thanks for the info!

Trying to figure out my options for a new ECM/PCM in the camaro. I believe a prolonged grounded 5v reference wire may have fried the 5v circuit/pcm. I've heard from a dealer and a place online that...

Hey guys, having an issue with a p0641 code I was hoping to get some help with. A code for every sensor on that circuit also throws, and the car won't come out of limp mode. Oil pressure reads 0...

Guys I was able to download the latest stable update by signing in with my serial number on the hptuners website. Just redownload the vcm suite after you get logged in. The stable build download...

Go to hptuners homepage and sign in using your Serial Number and password/app key. Of course mines not working and I'm having to contact support, but that's where they're getting the recent builds.

Nope, guess that's my next step...Thanks

Have deleted the OS file and repolled several times....no luck. Any other ideas? Been searching for similar threads....not seeing anything else besides deleting the OS file.

Russ,

I've just been trying to get the histo set up...I knew if MAF wasn't in Hz I was going to have issues so I've just been working on that. I've got 2 custom PIDs for AFR error, one I set up...

I'm just now diving back into the tuning world after taking a couple month break....trying to get re-acclimated with HPtuners.

I'm having trouble getting my histograms to show up correctly so I...

I'm really thinking its the fuel trims....will mess with it this afternoon and log some more and let yall know how it goes

LTFTs are disabled but I didn't zero out before I disabled them....does that matter?

I've been working on getting my MAF dialed in on my '10 Camaro LS3, just has Longtubes and CAI. I went out today and logged AFR Error on Maf Airflow vs. Frequency table. Once I logged and had the...

Thanks man, didn't read past Sensor calibration as I assumed I could do the rest with hptuners and didn't need the logworks software. Much appreciated!

I'm trying to get my Innovate LC-2 hooked up correctly. I'm trying to get the gauge they sent with the wideband to read correctly AND get the lc-2 to connect to hptuners and read the same. There...

Yea I can see that...seems like every log I do, the first time i hit the cells its a crazy number then the rest of the time is spent working them down. Seen a big difference on the gen 5 camaros...

So I'm working on VE tuning at part throttle. I've disabled the maf and done a ton of logging and tweaking and logging and tweaking, and I can't get the fuel trims within +/-4. The fuel trims are...
