Thanks for the video I’m just getting into tuning the main reason so I could just tune my own truck instead of paying every time I change a mod. This video was very helpful

You're making really nice material for the new guys man. Way too few are doing that stuff in detail and in a way that makes it accessible. Too much "secret society" BS in our hobby. I can understand why a speed shop and engine builder will not divulge all their secrets, but too many regular guys treat the basic stuff as was it a matter of national security. Ace stuff, keep it up.

Good video, good to see you got the eq right before driving it. Try using the multiply by half function when you get under 3% error, it helps quite a bit

Love ur street tuning vids mate helps people like me who mostly don’t have access to a dyno, one question tho are your main goals to get as close to 0 as possible? I see and hear a lot of people aiming for -2.0 % rich side, is it personal preference or does closer to 0 perform best? Doing mine currently and struggling a bit keeping it on rich side and fighting knock closer I try work table in, my table is a mess from factory so trying to build numbers in most areas just having hard time getting all cells to build numbers to then smooth in between. I’m in lambda. thanks mate

Hey Randy, look into transient fueling for the tip in issues where you spike lean then it catches back up as soon as you are going WoT.

Ok thanks Kyle. I’ll probably need some help with that because I’m not sure what table would control that. I can send you a log when I get done work.

@Bryce Reece I really appreciate your reply. I got to the site on google and Im in the hacking process atm. Seems to take quite some time so I will reply here later when my account password hopefully is recovered.

I'm curious if the math used in the filter against TPS being greater than 1 can be used on any other GM platform. Like a 3800 for example. I have no way to disable dfco, and this looks like it might be a great alternative to help collect data that is smoothed, rather than it getting skewed with so much lean data.

thank you very much sir, really helpful video, try disabling desoot mode in fuel-general maybe its causing that lean spike.

Great video!! great skills! Thanks for the video. Just a question, do the fuel trims need to be switched off when using Wideband sensors.

disable anything that adds fuel if youre tuning the ve table whether in maf or speed density... fuel trims add fuel so temporarily turn them off, then back on when youre done tuning.

Do you have any idea why turbo LS in a 2006 Chevy 1500 wants to die after I get in the throttle thanks

Does Paste Special X correct both rich and lean errors

I wonder what would have happened if the eq ratio was left at 12.03 ? Hydro lock maybe ? Or loose so much power that it would go out of power enrichment.

How did you setup your log to stop logging AFR ER when it goes under 1% TPS? thanks,Matt

@LowbuckLS

4 жыл бұрын

matthew williams if you watch the section starting at about 4:43 in this video I talk about the filter function that only records data when the TPS is above 1%. If you enter what I have in the function box at that point in the video yours should do the same thing. If it isn’t clear I can make a quick video showing that in more detail.

What injectors are you using?

Thats with stock decaps? I would think you're out of pump and the lines may be getting restrictive. Have you considered supplementing with meth? I think you mentioned you run 93 pump, meth would add some fuel and octane.

@LowbuckLS

4 жыл бұрын

Travis Pfannmuller yes my injectors are stock decapped truck injectors and I’m running 91 octane pump gas, we don’t have 93 around here. I think you’re probably right, I’m going to get a fuel pressure gauge to confirm that the issue is the pump/lines. Hadn’t considered the meth injection route, will probably upgrade the pump first and if that doesn’t solve the issue I’ll look into the meth injection thing.

Tried targeting 11.5/11.0 afr to see if that reduced knock on pump gas?

John I haven’t but I could give that a try, once the snow melts around here I’ll be ready to get out and do some testing and tuning in this again. I have a bigger fuel pump now too so that might help as well.

Should log your 02 voltage that good way to verify if your really running lean doesnt look like your maxing out your fuel pump or injectors you getting lean spike in a curtain area anything over 450 volts your running rich anything below your running lean

@LowbuckLS

charles deskins good idea, I log the O2 sensor voltage next time I have the truck out

Oh man I assume he fixes that 12.03 to the 1.203 right otherwise the injectors will go to 100% duty cycle

@@LowbuckLS gotcha. I have never messed with a gen 3.

just drive it around for a bit while logging. lots of different throttle positions etc then write it. also your power enrichment needs to be increased for when it shifts and when you stab the throttle its lean. your not out of fuel just keep adding. your VE is above 100% bechause your using forced induction obviously your volumetric efficieny is higher because you can fit more air than NA

1.203...not 12.033
