Drag/Acceleration Kia Stinger 1/4 Mile Times

[Tonkabob]

Bob did you post your data log with TPS? And agreed. Full throttle on the hit would do all we need to pull a decent 60'. You can't launch a Torque converter car any haigher than its hydro-mechanical flash stall allows. IT's not wet clutch trans. We are not going to get Higher RPM launch than TC allows.

Here are my 2 fastest runs that i have logs for - both 12.03s. The tune is slightly different between the two. We have been testing different things to hit the sub 4 second 0-60 and the sub 12 second 1/4 mile. The second graph has a small throttle pull at the 4-5 shift that i think Tork has a fix for. This shift bobble happens half the time currently. Also look at my timing during shifts often at 4-5 degrees vs 0 or negative for piggy backs.

Ok, what I need people to do is look at how smooth the ignition timing is and compare that to the other logs getting posted.

We have a fix for the throttle pull, but I am still looking for more power off the line

 

[KLR STINGER]

Yep, thats the way you want it to look. What do the shifts fell like?

 

[Tonkabob]

Fast and crisp of course. In the cases when throttle is pulled i can feel the difference. One bad shift can slow me by a tenth. The run after the 12.03 with one bad shift was 11.95 with 4 crisp shifts.

Again, an amazing looking datalog. I’d run it all day and not look back.

Any idea of how many hz this logger pulls data?

Sorry, I do not have that info.

Looks like 3hz give or take. Enough to give you a taste of the data, but not really fast enough to evaluate everything. It's still the most extensive Stinger flash tune log we've ever seen anyone around here post lol. So kudos to him for sharing the data. The way he's doing it looks like a lot of work relative to JB4 logs where it just spits out the chart formatted ready to roll after your run. It's interesting how similar the flash map boost, timing, and AFR looks to what we've been running in the production firmware.

Have we seen any Lap3-PRO logs to also compare with? I never got a straight answer if it even has data logging working yet? Would be fun to see the other flash tuners logs also.

Not sure about hz but It can do .1 second logs but normally i have it at .25. At .1 the ecu doesnt always seem to keep up as in you get repeat values for example rpm value didn't change. Its a $15 solution. Looks like jb4 is logging every .1 as they typically have 150 samples to my 50.

It is insteresting how similar they are, yet so much distance between the Dragy results

That just means you cannot log whats important in an ECU tune

11.95@117.3mph, 1.89 60' time, -0.99% slope, 4WD vs. 12.13@119.3mph, 2.06 60', -0.40% slope, 1WD.

I'm happy with how our car is running. When the weather clears up I'm sure we'll get that 11.9@120mph before we further modify the car.

We offer ECU tunes for use in conjunction with the JB4, posted unlocked and free of charge to our n54tech website, along with the TunerPro XDF files so customers can study and modify them as they see fit. I've also written ECU read/flash routines so I'm no stranger to flash tuning, or flash tuner BS.

1WD.

I think I identified a major problem with your car.

 

[Terry@BMS]

Tell me about it. On the plus side the RWD and non-LSD cars are probably the lightest weight. I think it came in around 4075# with me in it.

If the JB4 hits high 11's that would be amazing i need to see it to believe it.......Granted I have not seen a Full bolt on JB4 hit the quarter mile like Tork car but the reality is Tork has hit 11's no one else has.........One thing that i am not sure the JB4 does is hit those torque limits between shifts....on my JB4 between shifts i feel like the car holds back and boost drops i dont know if that happens with the ecu tune....

 

[Terry@BMS]

If you look at the logs you'll see boost is just mapped lower during redline. Might be able to hold it better once we get JB4 EWG control active. But it's also likely that we're better off just running a little more timing at higher RPM as I did in our last run. During automatic shifts the ECU drops timing negative for a moment to prevent damage to the transmission that might otherwise occur. I would not change that. In theory with a flash map you could increase the transmission line pressure, but normally that requires a special flash tune for the transmission itself. Not the ECU.

This might be a dumb question what is EWG control active? what does it do? when is it coming out?

 

[Terry@BMS]

It's something we need for the JB4 to properly tune hybrid turbos. We've got a couple customers working with those now. But the development might help stock turbo tuning also. Just one of the many Stinger projects we've got kicking around here. No set ETA. It would be an optional thing where you plug in a couple wires to the JB4 harness for it.

You are going to lose credability if you try to minimize your .18 gap using dragy slope when you know its not accurate. Its very possible your run had more slope than mine LOL. Plus your run goes up hill and then down at the end which you said gives rwds more traction at launch and elevated trap speeds.
Here is my slope test run for my new track that can read from .35 to .99. But we have already been through all this.


This was the old track that you said was invalid due to a dragy bug which is also BS. I believe dragy is considering a new feature/ algo but with the amount of elevation error they have they will prob never implement it.

Says the guy with no 11 second cars

I am right there with you on the weather cleaning up. When that happens, we will be able to get some runs in also. Don't forget, I have been queitly waiting for greatness to happen

God, you really have no clue how the ECU works, LoL!

With that being said, you are going to cause more engine damage with the elevated ignition timing and higher boost levels than anything we are doing with shift management.
