We are talking about LNF's not LSJ's. Big difference in tuning.

 

DI not port injection. Keep your car where its at.

 

yeah i just realized this was a LNF thread, woops lol.. I will be running meth once my reservoir is finished. It just seems to be running stupid rich around 11.8. Once i get it on a dyno I'll be able to mess around with it more than just street tuning

 

11.8 is great leave it there with the meth without meth go down a tad!!

 

hmm ok, just curious why I'm getting so much black smoke.. appreciate it guys, even though I'm in the wrong section lol

 

fuel trims can be wack. Ure getting wot kr. Spark blowout. And it could just be ure afr. I mean yeah 11 s is rich u will throw some smoke out

 

A little off topic here but about tunes. I saw you were in KY. A lot of people around here say that Phil from Bluecat near Ashland KY is the best GM tuner on the East Coast. Everyone tells me to take my LNF to him.

 

you drive a saturn sky convertible and you are calling hhr drivers gay only thing gayer than your sky would be you rockin a z3 with the music blasted with your wayferers on

 

Yeah i'll have to double check my trims, and I am getting a significant amount of knock here and there. I've been meaning to check my plugs, haven't had the time though. Good thing it's not my DD lol

 

I honestly love the sky! lol its about the only car that i would trade mine off for right now. And being convertable is a bigger plus! Easier to taunt "moon" vetts or old people in there exspensive cars when you blow by them haha just thinking about the possibilites cracks me up.

Back to the DRAMA! Yes.. If your car is black smoking when you floor it.. then 90% of the time your too rich period. other factors can apply thats why i say 90% of the time. Trifecta cars blacksmoke. everyone ive seen does. Your car doesnt black smoke like a diesel from the factory does it? Every car is different to its tuning needs. If you set the AFR to be say 12.8 then your AFR will be that at what ever boost "properly tuned" the car will add the extra fuel it needs for the added airflow and subtract it when nessesary. Just becasue your running more boost doesnt mean you need to manually add extra fuel thats where the maf tuning comes in. You can get the maf in the ballpark but not close enough with only one or two datalogs. This motor is still a gasoline motor so you cant go crazy lean with it. Thats my only arguement i have with "Gmtech if your reading please read my entire post". Yes i agree 100% its a new design! its technology! Its different than all other cars. Its direct injection which makes a huge difference in the capabilities and you can go leaner than any other motor out there. Thats why Im running a 13.0 AFr @ 25psi and when I check my plugs they arnt white or black. Its getting optimum fuel burn!

A while back when I was experimenting with my own car on E85. I ran out of fuel pressure. AFR went from .89 to .93 at 5500rpms to the rest of the pull "thats 13.75 AFR". I made the whole pull on it a couple times at 23psi. You could feel the car lose a little power of coarse since it wasnt getting enough fuel. No damage done. I would never run my car that lean on purpose again, but now i know how far you can actually push it. Mid to high 13s it loses power. Typically if you add more fuel you get more torque to a extent. 12.6 being the richest before it starts to misfire "on e85" or black smoke on gas. .89 or about 12.9-13 AFR seems to be that sweet spot for me and all the cars i have done.

 

So I did my AFR @ WOT on my way to work. I was generally around 14.7 driving around, but at WOT I went to 12.0-12.5 I guess that's good.

 

Well i didnt actually mean it was gonna blow up, just saying its not ideal. I know these lnfs can take some abuse.

 

[he may be the best gm tuner in ashland but its kinda hard to determine since people from ashland and close to that ive tuned and didnt say one word about him. I mean he may be a good ls series tunee which isnt.hard but lnf or lsj is a totally different boat lol. Id be glad to have a tuning session to see who is better lolB]i[/B]

 

Yeah I've tried to tell people that the LNF is different but they act like I'm retarded that I would rather have someone laptop tune my car rather than dyno tune with Bluecat.

 

Street tuning is better anyways and the dyno tune to fine tune..

 

 

Personally I think the other way around would be better. Start on the dyno and end up on the Street. I never liked any dyno tuning period though. I want the car tuned in the conditions its gonna be driven in i.e. Wind resistance, road friction, temperature, humidity etc...

 

HOLY F ING CRAP. You guys want to see a perfect example of a HORRIBLY tuned LNF? Look here...

EFR Tune Problems - HP Tuners Bulletin Board

Holy **** look at the fuel trims. Look at the PE. Look at the fuel rail pressure. Look at the KR. LOOK AT THE CAM TIMING! This is one of the worst logs I've ever seen, and I think you all can figure out who tuned it.

I'm sorry guys if you think I'm a dick, but seeing a log like this and knowing someone has paid good money for this tune makes me sick. Not to mention the birds falling out of the sky behind this guy as he drives with raw fuel running out the exhaust and no cat! THIS is why there's emission laws about this kind of stuff. He's putting out the equivalent pollution of about a thousand cars. (Fact, not an exaggeration.) This kind of thing is wrong "on so many levels" it's not even funny. You can blindly say "In Vince We Trust", but if your logs look like this I feel sorry for you and your poor motor.

 

wish i could see the log but im at work -.-

 

No litterally the best would be street tune so u can fine tune the car for numbers. Why spend 53748484 hours on a dyno when u can just do it over the street..

 

Im running 100% E85 also and I get no smoke and very little soot. Plugs are light brown.

 

I was tuned by Vince, I have nothing to say bad about it him, Im very grateful for what he has done for the community especially since it was the only option back in 07 for us boosted 2.2’s. But I will say I was very disappointed with my tune and his knowledge, When I 1st built the car we had starting issues, I had asked him is it perhaps the MAP sensor I was running, he told me there is no way the MAP could cause starting issues, well me being new to modern cars with ecms I trusted that, well after checking everything but the map, I was at my last my last straw and about to go back to stock, before giving up I changed out the map and the car ran perfect! And I have learned a lot since then and realize just how vital the map is to the fuel system.

Another issue was afr, it would always dump into sub 10’s at wot idle was perfect thou! held a nice 14.7 at cruise, after each retune it fixed it by maybe .1% Well after a year of emails and retunes, I finally gave up and went with a trusted local Hp Tuner. I find out my o2 sensor was not reading right. My last email to Vince about the car running very rich his response was check your wideband gauge……, The scary part of all this is after the o2 was replaced I decided to put the Trifecta tune back on to see how it would do, I had to cut the power off within seconds, the cars rpms were everywhere, sounded like it was going to die or blow up, the car just hated it, this was the tune my car has been on for a year??. It took my hp tuner 10 seconds to tell me hey the o2 is not reading correctly not to the point where it threw a code but enough to mess with the trims, Long story short I like my Hp tune better. Once again in no way do I mean to come off as angry or questioning his abilities I just think maybe hes better for different motors like the lnf or maybe Im a one off case or perhaps its email tuning Vs being in the car plays a role, which another great point of hp tuners there is no guessing or secrets all your info is right there for you to read.

 

Wow...... That poor car....

I think I'll stick to being a "self taught asshat"

BTW, thanks for the help a long the way GMT

 

Thanks T-Man! And you're more than welcome!

I know we've talked in the past, and you've obviously had an open mind and were willing to learn, even from a clown like me. I take it you looked at that log? I think anyone that understands anything about engines, even if they've never seen an HPT log, would be able to see there's major problems with that tune. For me it actually made me gasp, I was shocked to see how bad it was. I had exactly the same thought, that poor car! That log right there is why I stick my neck out to try to educate people. What was done to that engine and that customer was horrible in my opinion. The other huge factor is emission laws. That right there is EXACTLY why we have laws in place. What Vince is doing is clearly and obviously illegal, and in this particular case, the end result is a car that is literally spewing pollution out of it's exhaust. There is no reason for that to happen, it's simply caused by ignorance.

 

You should email that to Vince and ask him what's up

I have one of his tunes and I never run my car on "tuned mode" anymore cause some of his stuff I've seen is scary. I might get hpt someday.
