    HP Tuners - Video Guides

    Copying this over from Tech, with a few edits. Hope this helps some folks...

    I am making this thread to consolidate my growing YouTube presence and to make the videos easier to find and reference. I take no credit or self promote in any way as I believe these are a culmination or knowledge I have learned from the entire community. People like Marcin (redhardsupra), Bluecat, Ed M (RIP), ddnspider, Darth V8r, JakeFusion, DSteck, eficalibrator (Greg Banish) and many more have taught me more than I could ever thank them for. Sorry if I left some of you out. PM's are free...

    If there is a mistake in any of the guides posted, please, feel free to post here and correct me. I am always learning and accepting of new ideas. Tuning is not a stone cold set of rules, but rather an art. Please feel free to share your experiences and correct anything I might have wrong here, and share if something works better for you.

    This thread will be updated with new videos regularly as I post them to YouTube. Subscribe there or here. I would like to share as much as I can with the community, save some engines, and make some folks happy in their ventures.

    I realize those might not be in "order" for now, but I will change it as I fill in the blanks with more videos.

    All new videos will be added to this thread. That doesn't mean you don't have to subscribe on YouTube though. Help a brother out. These take tons of time to make folks.

    Seriously though, it takes days sometimes to put together a QUALITY 30 minute video. If you want to learn this stuff, it took us years to learn, a like and a click isn't much to ask.

    Tuning is an art and a science! and science is all about sharing and collaborating knowledge, thank you sir I will 100% check these out later!

    I definitely agree. And not everything has to be perfect either, which is something I battle with as I try to get ALL the numbers right and so forth... I can't think of how many times I've caused myself hours of work because I had one annoying (technically irrelevant) number somewhere that wasn't actually causing problems. Kind of like a lean idle creep or something like that lol.

    I hope these help you out! That's my intent. Let me know if you have any questions, but know that I don't check this forum nearly as often as I do LS1Tech. These guides are in both places by the way, and on YouTube obviously lol. I'll keep bumping this as needed or anytime I post a new video too, to keep it relevant and available for new tuners like yourself to learn. Thanks for the reply!

    Very cool for posting these videos. Will be using these to tune my 57 this week. Thanks!

    I might redo my MAF guide to clear up a little confusion using STFT's vs WB as it has occurred to me that some folks don't have the extra "bung" to install the WB AND enable and use closed loop. My bad on that lol. Have someone that is trying to tune using closed loop with an O2 removed. I feel now I have to correct that in the video. I will still cover STFT's since for part throttle areas, but you would do this after tuning with said wideband, tuning everything including WOT, when touching up the STFT's after WB is removed and upon putting the car back in closed loop.

    That should would work regardless of extra bung or not. I'll work on that this weekend and clear up the confusion there. Last thing I want is to confuse folks, so I feel this needs to be rearranged a bit.

    Any chance you could do a ve tuning with the narrowbands? Also rrt? I am also confused if pe is supposed to be disabled when doing ve or not?

    Power enrichment should never be disabled. You can raise the thresholds so it's not as easy to enter PE but it shouldn't be disabled. Using the scanner, one could also create a graph/chart with filters so that it won't take data you don't want to use.

    Remember that narrowband sensors only work in closed loop, you can't tune full throttle fueling without a wideband o2 sensor so you are better off just buying one from the get go.

    i have one, but dont have a pro and didnt wire it in to the pcm. I use it to look at and kind of check that its close. its a NA car, and a 03 truck 6.0l, so pe was pretty much disabled stock. Thanks for the filtering idea. Right now, when i enable the stft when doing ve the table is +- 3 and i have the maf less than 2 when doing the maf tuning. When i re enable everything, the ltft are 0 at cruise, but its pulling fuel in the lower areas and adding in the upper. I re checked the ve and maf and they still show they are the same. What is causing it to pull and add fuel?

    Pulling fuel is still fine. If it's around +/- 5% I wouldn't even care.

    I find trim tuning harder/longer because of how the o2 sensors work. The wideband error is just so much faster and more precise.

    On a stock 6.0, I do suggest a richer air fuel ratio for power enrichment. 12.2-12.3 is far better than 12.8, probably makes more torque being richer too. The timing curves should also not be mirrored, you have a lot of knock retard in those logs and it can't pull any of the timing out because the timing tables are using the same values. Bump up to 89+ octane if you are running 87 pump gas. Double check that you have zero pending knock sensor codes too, if there are any it will spike the knock to 8 degrees like you log shows. Pull lots of timing if it still knocks, you may only be allowed to get away with 20-22 degrees and not 25-26 like you have in the mid range now.

    it was on 91, always. Maybe a bad tank, there is not normally any knock in the logs. Ill change pe to 1.2. I just drove 3500 miles with the car and got home last night. I will get the wideband in it to check it out. Ill put the stock low octane table back in it. The spark table is the stock high octane on the top half and a 02 camaro on the bottom. I did add like 3 in the cruise area. Ill do some more logging to check it out. There are no pending codes and i checked to make sure they are still enabled.

    Thanks for any help, i do appreciate it.

    So, I finally got my high IAT taken care of and am ready to start tuning the MAF (the VE is done) I removed the WB to be able to use STFT using the O2 sensors. I'm wondering how I will go about tuning the WOT MAF since I need the WB to do this. I don't have a third bung for the WB.

    Use the wideband to tune the MAF.

    How else would you go about it?

    Put the wideband back in and tune the MAF in open loop using the wideband error. I can only assume you did that when you calibrated the VE.

    Got it. Thanks.

    Didn't realize that I already had the data I need from when I tuned the VE at WOT.

    Updated the MAF tuning guide, to a newer easier to follow version. Also, I split the video up and made the MAF baseline in SD it's own video.

    Excellent. It's much clearer now on how to setup coming out of VE tuning. The MAF baseline video is very helpful too as that was still a bit fuzzy to me.

    Any chance you doing something on tuning spark?

    Very interesting knowledge, but why all such info I find based on GM? Is it because it's more complicated than Ford? Lol
