Drag/Acceleration Kia Stinger 1/4 Mile Times

[StungBlueGT2]

RC kind of fast, jb4 fast and cheap, lap3 pro and ecu tunes really fast.

I mostly agree. But I believe you’re basing that statement on current 1/4m results, correct? As you know those numbers will keep changing and just depend on how many people with each tune provide results.

So I simply believe your grouping of these upgrades is misleading. The lap3 & jb4 are both hybrid style chips and are almost identical in tuning capabilities. Anything the lap3 can do the jb4 can do as well...

Not to mention Terry’s Stinger is making a lot more torque 531tq vs 505tq without DPs or any exhaust! The main reason lap3s producing more HP is because they are dangerously pushing over 23psi! Even lap3s 540hp “world record” Stinger still isnt producing as much torque as the jb4.

All I’m saying, is if you’re putting the lap3 at the top with tunes then I believe you must include the jb4 as well since they are basically the same chips.

Here’s a question that someone should be able to answer.

So are the piggybacks also increasing the open loop/non-WOT performance?

Most of my day is spent under partial loads and normally driving, I would love to have more power at all times. It would reason they would be able to constantly adjust values as you drive. I know quality ECU tunes can adjust both but a vast majority only touch the closed loop.

Yeah back to 1/4 mile topic! Just looking at the results so far lap3 pro is faster. Not saying thats all good and they wont break something running 21.4 psi. jb4 is maxing out at 18 to19 psi on dynos I've seen
Can't tell you why and a bit off topic but currently ecu tunes and lap3 are ruling the 1/4 mile. There is no doubt about that.

Sometimes it’s as simple as some turbos peak higher... but overall I think it’s because it’s all about the numbers - they are probably more willing to push their turbos harder.

Have comparisons been made between some flash tunes, some piggybacks, etc., all with equal (preferably slight) modifications?

 

[Oryan]

That’s unfortunate and here’s hoping it doesn’t happen to anyone else. What piggyback chip did you have installed? What brought you into the dealership and do you believe the issue you were encountering was caused by the chip? It’s good to hear all sides, but if they can detect that I ever had a chip installed then I’m screwed if I need warranty work, therefore I will just enjoy the performance and not worry about may potentially be, given there’s nothing I can do about it now.

It's not easy to detect a good piggyback but if a dealer has reason or desire to dig deep enough they'll find it. It's easy to detect a flashed PCM because the tables and their target parameters are all clearly not stock. It's possible for someone to realize you swapped PCMs too if they're looking for data that the switched PCM won't have due to it not being in the car at the time whatever broke. Main way a piggy back gets found is by looking at logs of engine performance, it'll see commanded and actual targets like boost, AFR and timing that either don't match each other or won't make sense and be inconsistent for a given engine load or clearly faster than stock acceleration runs. That being said..NOTHING voids your warranty. It's getting really old hearing that again and again. A modification that a dealer can prove lead to that specific failure is grounds for them to not make a claim on that part, but they can't jusy deny the whole car. If your stereo starts having the fader issues or your paint starts peeling, for example, they won't say no because they found a piggyback and intake on the car.

I just have my own for my near stock AWD.
RC 12.7
Ecu tune 12.4
Same mods on same car, same temperature, same track, different days. (.1 of that was in the launch)

What was the temperature, altitude and humidity like? I have a JB4 and K&N Intake, and I run steady 12.4s. AWD, also.

I’m sure someone can explain further but when I drove my friends on map 2 it would spin tires at half throttle.You definitely didn’t need WOT for it to add more boost under normal acceleration. Believe the “target” boost % adjusts real-time based on throttle input.

True. Currently lap3 is ahead if only considering 1/4m times. But again that’s limited to who’s testing their cars and providing results.

Lap3 is all over social media lately promoting their HP records which recently amassed a following of Stinger owners. They simply have a lot of new people testing their products and willing to push the limits of our Stingers. I do agree and bet they will be the first to break something serious, especially pushing over 23psi(1.6bars according to their latest dyno).

I’m just saying since both chips can make the same adjustments the jb4 & lap3 can and will produce very similar gains and 1/4m results.

A drop back for those of us living in Cali, the JB4 can't be shipped to us because of Cali emissions. Hard to know how much that could be hurting sales, given the few folks that live in Cali. Large market!!!

You could ship to an out of state relative or friend and just have them send it to you. Just got to think outside the box.

In short, no. It's extremely hard to compare the current 1/4 mile times (or dynos even) from different climates, with different mods, and different tunes.

I hope to take away the lap3 AWD record in the very near future.
Doesn't lap3 have more connections like that nasty to reach one under the downpipe?
Also agree the lap3 cars tend to have more mods.

What’s their best AWD time so far?

The lap3-pro guys are promoting that 480whp dyno they did with meth, downpipes, exhaust, etc, etc,

I think you're asking the wrong question because modern ECU's run closed loop of wideband sensors full time all the time, except when you first start the car for 30 seconds while the sensors heat up.

In terms of the JB4 we've programmed it to map boost off gas pedal input so you get a linear and predictable power output depending on how far you press the gas. This is also the reason the JB4 drives smoother than the other piggyback options. But we also recognize some customers prefer the feeling of a "boost bomb" at low throttle so we have an option to let you disable pedal input and have full target all the time.

 

[Tonkabob]

Awds
12.07* lap3 pro mid pipes intake
12.08* me with full cats and mufflers fmic intake, tune.
12.13 lap3 pro intake fmic down and mid pipe
*dragy times.
I'll update the leader board tomorrow with my 11.99 that i havent run just yet

Yes they have an extra connection that runs down to the CPS, but this is redundant. It’s used to monitor engine speed for timing control but that also comes off the CANbus. No difference in tuning ability.

Yes most lap3 cars are basically running FBOs, or at least DPs & exhausts. Secondary DPs are good for about 30hp and bet primary’s would give 40-50hp. Thats good for another .3-.4secs, and why I’m sure jb4 Stingers will match or beat any chips available.

But we also recognize some customers prefer the feeling of a "boost bomb" at low throttle so we have an option to let you disable pedal input and have full target all the time

That sounds like fun!What setting disables pedal input? Or is the sensitivity to pedal input adjustable?

Prediction comes true.
New AWD record. Still have cats and muffler. 11's so close!

I think if using dragy, we should run the same run the opposite way and average them. You might find you hit that 11, car has tons of TQ out of the hole.

Great run, and that’s balls fast!

I wish Balls was that fast. Lol

That sounds like a good idea but super hard to find flat road you can drive 120 mph on safely and in both directions makes it even harder. 1% grade is barely visable. I'm using flat highway on ramps. This one has a turn in it so certainly scrubbing speed.
