I don't quite get the concept of changing OS/platforms...

Interesting. I don't have UDP yet (an extra $169, ouch), but I did open your XDF in TunerPro. Which table would be the fuel to wall transient table? I've attached my injector data and the only thing...

Pretty sure it's a GTO OS. The ECM is from a van which happened to be a blue/green that still has drive by cable support.

Hey guys, I have been working with a P59 4.3L V6 ECM that was originally recalibrated to a 2004 GTO in order to work with my setup. All info is as follows:

Hardware: P59, GM Gen3 V8, 4.3L V6...

After a few years, I've finally found some time to tinker and tune the recent LS6 intake that I installed. Last time I was running 2.24 with my tunes. I am now on 3.6 and I noticed something goofy....

Weird. Is the IC piping similar? What about the clocking of both MAFs? Maybe one MAF is acting up?

Well, for starters, your friend is using a Gen 4 ECU, no? The calcs/algorithms are probably different between the two generations. Second, how can you say that flow should be the same between a truck...

Sounds good to me! I'll try and toss 'er on a dyno here soon. Thanks James!

Just to mention it, I do have stock injectors and this is on a 5.3L LM4. I also noticed a faster cranking as well, where before would catch after a couple of cycles and with EOIT increased, it...

Hey, thought I would bump this up and see if anyone is still playing with this idea. I had this weird power dip right after idle to rolling and stumbled (like the car, ;) ) into this thread. After...

How small of a cam?

I find it hard to believe that a single lean spike (which could also be a misfire, which could be either too little or too much fuel) is going to take a piston out like that....

Sorry about that guys. I pulled the file thinking it was the post wideband tuning tune, but it wasn't. Sloppy file management led me into creating another one, so here it is: 41690

I still have a...

Hey guys. After some work with a wideband, I've got everything dialed in. From VE to MAF to RAF, the car runs great. The only part I am having issues with is off the line throttle response. Going...

I'm curious towards what type of computer hardware you guys run. I take it everyone in here is running at least a standard hard drive and not a SSD? When I started tuning a while back, the laptop I...

Dead on, David. Thanks for the advice.

I ended up tuning the RAF after the VE table was dialed in, and everything came together and driving the car is SO much easier. It wasn't much fun having to...

Alright. I gave in and started with a stock GTO tune along with a slightly stronger spark map. Went out with the wideband and I was pulling 11:1AFR at idle. Oy. The WOT pull fuel seemed to be right...

Alright, since no one is willing to at least point me in the right direction, here is what I currently have running the car:

Issues:
- On cold start, the engine jumps to 2000RPM and stays there...

Anyone have a decent base tune for a 5.3L with a 224/224 cam? Here are my specs:

5.3L LM4
- TSP 224/224 .581/.581 LSA114
- LS1 intake/injectors (28#)/injector rail/MAF/MAP
- Longtube headers

So, unless HPTuners decides to drop the x86 version today and write an ARM based touch only version, don't expect this anytime soon. As for regular Windows 8, I've been running HPTuners betas...

Bump. I am having the same issue with the beta. I can log hours on end with 2.22, but the beta randomly freezes and quits collecting data.

This wouldn't be an issue if I could run the beta editor...

I've gained a good 3-4MPG out of EC_Tune's O2 tables. I do see my LTFTs pulling as much as 20% in those lean conditions. Is this normal? After changing the O2 tables, do I need to retune the VE...

The base MAF information can be pulled off of a stock tune from the repository on here.

The STFT swing between different days can be as simple as a change in density of the air, which a MAP can...

Hey guys,

I finally worked out a tune that is clean and does not have any knock. Idle is fantastic and everything feels the way it should be, except decel. I am currently tuning VE via the BBE...

Yup, I've been digging through a bunch of the stock tunes. I've heard that at least the '99 LS1s can't handle the 85mm MAF, which is what came stock with the LM4.

I did finally stumble on the...

The harness I am running is custom built. If you are patient, I actually recommend it. The harness becomes a lot cleaner and easier to deal with. I started with 2 truck harnesses (can be done with 1...
