I was told it?s a 2001 5.3 out of a Silverado truck with a TSP torquer v2 cam and headers. The swap was done back in 2017 and now has about 12k miles on it. No idea who did the original tuning but...
Yep. 12555894. Appear to be stock GM injectors.
Fuel system is Walbro 255 pump and corvette regulator. Tested at the rail at 52psi.
No EGR and no cats, I believe stock injectors but not sure as I am not the original owner. It has a return but it's before the rails. I hadn't noticed the EGR and catalyst tables where populated so...
Ah hell. You are right. Was looking at the wrong stinking graph. I see it now. Oof. Ok time to do some more reading up and testing. Thx.
The log doesn't show any STFT data until after the idle starts to even out. During the initial 30s of rough idle there's no STFT readings being logged so I'm assuming it's running off the VE tables...
So why does it even out after about 30-45s even though it's still in open loop? Is the MAF in use even in open loop? I wondered if the VE might be off but I figured if that was the case it would run...
I just do simple minor tuning stuff at home on my own car so looking for some guidance from the experts. Car runs pretty good for the most part except after battery disconnect. After the battery has...
Yeah will start with the filter/regulator and go from there. Thanks again.
Slapped a tester on her. Yep, 29psi ain?t gonna get it done. Appreciate the reply?s.
Yeah I guess that was kind of a stupid question. Thanks for the reply nonetheless. I'll get a gauge and make sure pressure is good then move on from there. Thanks.
No doubt. And that's next on my list but before I go down that route I just want to make sure it's a likely cause. Would loss of fuel pressure or flow create a lean condition like this? Would it...
Hey all. Like a lot of folks here, I'm learning things as I go. I've had my Gen 3 LS for a couple years now that was tuned by a knowledgeable tuner awhile ago. It's run pretty decent over that time....
That was a good catch! Right now I still have that table zero'd but plan to dig deeper into those values. Right now, with the updated timing and shift pressures, it's feeling a lot more sane. I'm not...
Yeah the PO’s tune seemed like he really didn’t care much about the trans life lol. I’ll make those changes as well. Thanks guys. Really helpful!
Ok I changed the shift pressures and shift times and it feels a ton better. Thank you guys!
What would you suggest for the Torque Reduction settings if any? Right now they are all zeroed...
...
Ok, I made the suggested changes given. If the changes shown look good, I'll load it and take her for a test drive and do some logging. Really appreciate the input!118330118331118332
Thanks for the input. So turn torque management on and adjust the shift times. I pulled the Torque Management values from a stock tune and followed 13qtr's suggestions for shift times. I wondered...
Hello gurus,
I'm running a cammed 2000 5.3L Gen3 + 4L60e + 3500 stall installed by a PO. I'm trying to actually reduce the firmness of the 1>2 shift, especially when cold, as it feels way too...
Just picked one up from Summit Racing and got it in 3 days.
