Well, I got my tuned car Re-tuned recently for more lower end torque. I'm now driving an SS TC with 360 Lbs torque most of it lurking between 2000-4000 RPM. My car is now a ***$$$N monster
I'm slowly getting used to driving this..but this baby wants to rip at the slightest provocation of the foot peddle. Damn, it's like riding a race horse that wants to BOLT at times. I'm slowly getting used to *STREET DRIVING* it now. Anyone here with the same experience? Tips street driving around town?

 

What tune? Did they turn your torque management down?

 

With HP tuners you can adjust throttle response.

 

I really gotta mash it WOT or not much boostage

 

He used the HPT suite. Said I could increase torque lower down, even though the tune I had was pretty decent. I was told people here get rubber when floored in second. My car didn't do that (and some thought that was reason to believe the car wasn't tuned in the first place) so I thought *go for it*. Now it lays rubber alright!
Here is the chart..note that the GREEN line is the baseline and Blue after the tune...we were both pretty surprised to see the baseline to say the least.

 

you need to get your tune adjusted I think

 

and on a real dyno lol

 

What would you recommend based on that chart then?

 

what are your mods? you could probably get a little more power out of it. but your torque drops off way too fast..

 

he's bonestock

but complaining that it boosts with the slightest throttle engagement is what I'm understanding

 

There are NO mods at all. I added the GM tune to the graph here to compare. GM tune shows to the FLYWHEEL #s, but I think the scales are close since this dyno *reads* higher than dynojet by around 7-10% and the drive train loss (to wheels) will be about the same, so the actual #s on my dyno graph are pretty close to flywheel #s...give or take.
You can see at 3000RPM the differerence in torque is around 50 Ft Lbs over the GM stage 1. From 3500 to 4500 GM gains on my tune and mine drops. The gap then closes to zero diffeence at 4500..then GM falls way off after that.

 

i have a nice hp tune. at about 40% throttle or less, the car is as meek as a lamb.
you couldn't tell the car was even tuned. after that all hell breaks loose. (above 40%
throttle). if your car is not like this, it sounds like your airload tables are messed up.
if your torque vs. rpm vs. gear table is set too high in first and second, this could be an
issue too.

also, who did your tune?

 

holy **** that dude in the bmw ahahaha rofl, his buddy runs up to him, **** id be laughing so hard, damn its hard to type. That made my day and more.

 

Have your tuner run the stock DAL (Desired Air Load table) until the 80% load column.

I set mine up for WOT in the 100% column the way I wanted it then interpolated horizontally from the 80% to 100% column to smooth it out. He'll know what I mean.

That way you won't light the tires up every time you want to just roll around someone and the torque will still be there when you want it.

Lean it out to .88 lambda while you are at it. He's probably used to tuning LSJ's more than the LNF.

 

that's kinda what i was saying, you just were alot more descriptive. also the max airload torque table
could be set too high too soon. BTW, i just installed the "pill" and BYT's pill mod tune. that was a PITA. (installing the pill).
i like the results!

 

Well, I figured he can print it and give it to the guy if he wants.

I ran the pill line up top by the intake so putting it in or taking it out is a breeze now. I leave it out in the hotter weather unless I want to romp on someone. I see 24 psi without it at 4500 rpm, tapering down to 17 psi@ 6500 or so.

 

usually tuners will tune so you have driveablility. like you could drive in town, shift around 3k and not see boost or feel too much power. But when you get on it, its beastly. So idk either you wanted it like this or he tunes weird.

 

that sounds sweet. i would like some pics of that please!

 

Sounds like the DAL are outta wack

 

It doesn't light the tires when a punch around a car. I drove it a lot more yesterday and I'm getting used to it now. The car is just as fast form 60-100 as it was with the old tune (Green Line)..I timed it again. That makes sense, since the torque curves are almost the same from 4000 up. Like I said, I get tire chirp in second now, which I didn't get before and the car flys in the mid range where most driving is done. I'll keep eveyone posted in the next day or two. Thanks for the feedback.


I found this dyno graph posted here under *dyno results thread* here and it looks a lot like mine. Except my car reaches 360 FT Lbs @ 2700RPM vs 200 Ft lbs for the other car and 350Ft lbs @3000RPM vs 250Ft Lbs for the other car. Thoughts?

 

Sounds like the DAL tables are definitely out of whack. You should really only adjust the DAL for 80% and up for sure.

The LNF requires completely different tuning than an LSJ, or any other car for that matter. You really should only get an LNF tune done by someone who is familiar with tuning the LNF, else you end up with all kinds of weird problems with AFR, DALs, drivability and others.



This probably has to do with the way the max airload tables are configured.

 

I have some someplace with the hahn intake I think... yep.




Ronn - properly tuned with TC off it should smoke 'em 4k to redline in second if you just floor it at 3500 rpm. You have more HP on the table if you want it. You should be able to make the clutch slip if you want to in third when you nail it at 55-60.

Just my two years experience with the TC talking.

Not the max airload tables, prob the desired tables need some work. I told you earlier how I'd set them up. Max airload can & should be 100% 2700 rpm & up.

 

I have to tell you, I'm getting used to driving this car and it's pretty frigin' nice. I have a ton of torque on lower rpms now that I didn't have before and the car is very driveable.
It just looks like the entire curve on my car has been shifted about 1000RPM lower (to the left) compared to the other car. What's wrong with that?

The other car I'm comparing mine to in this chart below has the following mods (no specifics):
Intake, Catback,DP,GMMP Cat delete, Tune



Mine is BONE STOCK.

 

There is nothing wrong with it. They just have your max torque tables ramp in at lower RPMs.

 

Well..I finally get an answer I like!

He told me that's exactly what he wanted to do...works for me. Did you notice that my car STOCK is damn close to that other car (ChillonDillon) with all the mods? I'll post some his pics here..I'm sure he won't mind!

Other pics of *ChillonGillon* car that I'm comparing my stock car to:







That brings into question how *much* are these mods reallly worth?
