01 5.7 ls1 vette

[Army01Vette]

I have had help on the forums with my tune and I'm very grateful for it. I'm able to drive my car but the tune is still way off from where it needs to be.

That being said, is there anyone experienced in the Scottsville/Bowling Green KY area that would be willing to assist me in person at some point. I don't have a wideband and won't be able to get one anytime soon. I have 5 kids that take all my money atm lol.

I've tried youtube to educate myself, but it seems like everything I attempt ends up not working out.

Thanks in advance.

Can you post your tune and a log. Also vehicle details and mods.
Is it all stock? cam? injector part number? We need details and files to help.

TSP Madd Maxx cam, Injector # 12561462, Borla S Type 2 axel back, and that's about all I know.

TSP ?MADD MAXX? Cam Specs: 228/232 .550"/.550" 110+5
You only need to log O2 mV for the front 2 sensors, get rid of the other ones in the scanner channels.
Log cylinder airmass.
Log TPS% and TPSv
Log MAF (frequency)
Log dynamic air
Unfortunately, your tune isnt in MAF only or VE at the moment, so the data is junk. Heres your tune file set into Speed Density mode with some other changes to the VE on the low end and i re-enabled the fuel trims for tuning. The VE was just an arbitrary adjustment based on the cam profile. You need to clear fuel trim adaptives and take a good log. Use the fuel trims since you dont have a wideband and dont get into WOT or PE, since trims cant track the data in those regions.

Thank you for taking the time to do that. I'll change those settings and see what happens.

after a short run in the parking lot at work, my scanner stopped while driving. I think the usb port is getting loose.... here is that very short log. I cant find tps% and it is reading 0 for tpsv

thanks

This is a run from work to home this evening.

You need to setup a graph in the scanner. STLT+LTFT vs MAP vs RPM. Might add a couple filters. VE has a decent start, but looks to be a little high in the lower map areas.

Thanks, there is already a graph in the scanner setup for that. It's the one labeled LTFT + STFT

Graph setup doesn't go with the log file, so no one can tell what you are graphing or seeing in tables from the log file. it's the raw data that shown in the channels. You have to post a configuration/xml file to see "your" graphs. Or has this changed in the newer stuff?

I'll have to see if i can figure out how to do that. I've only seen people post the log file and didn't know it didn't show everything I can see on my end.

Yeah but with the data provided in the data log you should be able to setup your own graphs to reflect what he's talking about.

OP that B2S1 is super lazy. I'd replace them both because, you know, shoes.

I was just pointing out that ns158sl can't actually see what he has for graphs.

I was thinking the same thing. Still curious why the TPS isn't registering any voltage.

Because a Vette has ETC. The person that told you to do that probably thinks it is a cable throttle body where that might be relevent. There is no need to log that on a ETC unless you are having REP problems then there are other voltage PIDs for that.

You are correct, I did not think about it being a DBW.

ok, thank you, that makes more sense now.

I decided to bite the bullet and do training from HP academy to try and learn this stuff. Hopefully I'll be able to get the just of it and do some good tuning after I've completed it.

Those 5 kids don't need to go to college.

nothing you will learn on there will be any different from the 40 of us in here giving you the training

I spent years on this forum and online forums like LS1tech and performancetrucks.com trying to learn to tune before i ever made a post in here. I had pretty good luck just learning from the forums and using my own knowledge of cars to learn to tune (i was a master tech for over a decade, so that helped). I started buying tuning books and dvds from greg banish and LaSota Racing. A few years ago i decided to take some classes, because, i thought, i was missing something important or there was secrets that i hadn't learned while doing my own research. So i started with EFI101.com and literally everything on the courses, i already knew. A few months later, still being convinced i was missing some kind of trade secrets or something, i signed up for High performance academy and completed all of the stuff they had to offer that was tuning related for gas engines. Again, 95% of it, i already knew from studying online and reading on here. I felt like most everything they taught in those classes was basic knowledge that was pretty easily attainable if you looked (especially now days). However, i will say, I thought Evans performance was best for the money. You're able to pick which software you want to be trained on (HP, EFILive, ETC) and he actually shows you tables and relevant things that will need to be changed or edited. Its also sectioned off for things like VE, MAF, Idle, Timing and not just one long video that barely touches on each. But again, nothing i saw on any of the "schools" was any secret that couldn't be found online for free.

My point is that you don't have to pay for that stuff to learn it. There's lots of written guides floating around out there now days and there are a lot of people on here and other forums that help out. I know people learn differently, some are hands on, some are not and I'm not saying the classes are a waste of money, but they aren't necessary. 10 years ago it wasn't as easy to google "VE tuning" or "EOIT" and have much luck finding the info you were looking for...

[Army01Vette]

I think I agree with you. I have learned a couple things, but nothing I couldn't have found somewhere else.
