Lozic ECU + TCU + AWD Tune

[djerickd]

Aren't PS4S the best?

 

[StingertimeNC]

yes but I'm getting ready for a two day event at VIR and I'm figuring I'm going to destroy the tires, so hoping for something a bit cheaper but still good for the track. Could even be raining, who knows. After this set, I'm thinking PS4S. Unless I get the track bug, in which case I'll stay with something cheaper and just figure on replacing them every 18 months or so.
Edit, I only drive the car about 3.5k miles a year.

Yes, I love the way it shifts, but like you said it feels a lot like your M5. It is not a M5 and the trans of our Stinger is not made thinking of a M5. I'm just a little worried it won't last long, especially the way I drive.

It's kind of funny - when I got a re-drilled valve body for my Legacy GT, they claimed more clamping force (higher line pressure) would make life EASIER on the transmission, due to less heat / friction because the clutch disks would spend less time slipping / heating up due to the harder shifts. Now I'm hearing the opposite about this mod. Or is this stressing different components?

How hard are you at the track? I did an HPDE1 (novice) where I thought I pushed the car somewhat - obviously not to the level of some of the other guys, but still, I wasn't the slowest one - and my PS4s (18" on Enkeis) picked up some track gummies, but overall, don't seem to have worn too much. Did way more damage to my OEM PS4s with that (*&@#$ drift circle I did at the auto-x school. Tore patches off 3 of the 4 tires.

@Avant - You will find the TCU adapts over time and continue to improve, so watch out for that and let us know what you think.

I'm a novice and will have an instructor for at least some of it. I'm gonna work it but want to make sure the car makes it out in one piece for sure. Going to VIR. The only other time I've been to VIR I spent some time riding in a G70 and the brakes took the most abuse for sure. I really didn't pay too much attention to the tires as it wasn't my car. I noticed some serious wear around the edges though.

 

[Jaybone]

I ordered the same

I think based on the math that should be the sweet spot

 

[Avant]

Hey Avant, quick question, what tires are you running? you like them? are the decent in the rain? or dangerous in the rain? I need some new ones and looking for something that's decent on a track but that I can reasonably drive on the street too. the tread looks aggressive.

I am running Nitto 555s. Not the best in the rain. PS4's would be better.

Good to know. What did you notice once it adapted?

About gearbox and higher line pressure in TCU

With higher tune, more power and torque and more slips in gearbox turbin and by that more heat and wear. So with higher torque we need higher TCU pressure to be nice to gearbox turbin which you can compare to a clutch. With factory settings shiftings is made with turbin slip, ignition cut, boost drop and so on to make shiftings soft and not even to be noticed. A stock car should be as smoth as it can.

So higher pressue is needed for our tuned Stingers but of course the rest of the drivetrain, like driveshafts, differential, cardan shaft & knots (I dont know the words here) will take more loads as TCU/ECU produce more tourque by less (faster shifts) time with less slip.

Worst for every cars drivetrain is wheeljumps so try to avoid that. Stiffer back springs can make that jumps worse. Thats why guarter mile cars have soft suspension and also soft tyres when they go to the track. It will take up a lot of the drivetrains load when launch.

And last... gearbox/drivetrain will hold together as we dont run WOT all the time and also not launch so often. Of course launch is worst for wear and tear but shiftings at WOT are gearbox like even better with more pressure.

So to decide pressure I think 90% of us should go for pressure 2 and the rest with full bolts on and chasing 1/10 of seconds should go for pressure 3. These pressures are max pressures that is calculated by tourque, rpm, gear, temp etc. so when you order the pressure it is the max pressure you can have when you take out as most torque you have. In ordinary driving you shouldnt notice much at all as the pressure almost (some higher) is the same as stock.

I think that it is the ECU that adapts to new TCU settings. TCU ask ECU for values to shift like rpm, torque, ignition, speed and when its fullfilled TCU will shift for us.

Getting really excited for my ECU tune. Lee Sung Woo and I have been going back and forth on a boost-by-mode feature so I can dial it back when I want a more relaxed drive or turn up the wick when I need the power.

So far it looks like 0.3bar in Eco, with highway acceleration similar to your typical entry-level sedan; 0.7bar in comfort and the balls-deep 1.5bar in Sport. Boost control looks dead-on, too. My mk6 GTI would overshoot constantly by 10 or 20% before the wastegate dialed it back. This is perfectly damped - it approaches the target boost and stops. No overshoot then correction a half a second or a second later.

Well 1.5 bar is the same as 21.75 psi tune. I have no doubt that running anything harder then what was designed from the factory will reduce its life expectancy. But just like anything if your not out going WOT everywhere you go and run the proper octane and do good matinence it really shouldn't be that much of an issue.

Hmm, 1.5bar ain't bad then! I've read that some people are talking about some sheet? picking out what you want I guess. would anyone have one just to see what exactly I can add or change? id want an ECU and tcu highkey.... want to leave some people in the dust.

We’ll if you want loud bangs/flames you’ll need to be catless all the way through the exhaust. I saw a video on YouTube where the owner claimed he blew his high-flow cats and turbo seals within a few weeks with the tune he had..(which was a different company) but it’s still the same concept behind creating pops/bangs.

No one with the lozic tune has had this issue but not many people in this thread are running loud bangs on their tune, some are running soft pops though. The 3.3t engine is stout and has shown the capability to handle ~500whp range. The issues I’ve read with tuned stingers are the turbo failures/ turbo seal failures causing a loss of oil which ultimately will ruin the engine.

man f*ck that cat lol... I definitely want that!!! would I only be able to choose pops and bangs with flames? or is it pick one or the other type of thing?

Yeah, that makes more sense and thanks for calling that out. It's good to be accurate. I would actually like to know more about this. Do you have more in-depth details?

I APPRECIATE IT! thank you

 

[Jaybone]

Gents I apologize if I have asked and had this answered before. What was the time frame from when he ships to arrival to your home?

 

[SnowyGT2]

Remember seeing 2 weeks to the states by someone here

 

[DrewA1]

Question, if going catless primaries does the ecu tune clear the CEL?

 

[Corleone1]

Thanks!
No, i dont have more just with Kia´s way. But I know when we go aftermarket ECU like Syvecs that we use on GTR, Porsche Turbo etc. there is several ways to cut between shiftings. We use fuel when we cut and not ignition and doing things with trottle at the same time. It has to do how fast the gearbox mechanical is and how its best to do it to have as fast shifts that can be allowed compared to the hardware.

Porsche has a faster gearbox than GTR and also can move 2 gears down in the same movement. I will ask my tuning/building friend, who is best at this and see how he will describe it. He is on holiday now but I ask when he is home.
He has a new own built GTR with 4.1 liter and like 1800 hp in a concervative new Mustang Dyno. I can say that it is scary. I have 1100 awhp in mine and up to like 100 mph it isnt any difference as traction limits. But then, omg, like 124-186 (200-300 km/h at aprox. 2,5 seconds and acceleration just increase by gear as traction allowed it. He runs traction controll by GPS directly into Syvecs ECU.

Cars is fun!
