Lets talk tuning, piggy back vs ECU flash.

[Manaz]

No, we have tuned several Stingers, most just happen to be overseas right now.

This was something I was hoping to get to once I read through 49 pages of... "interesting discussion".

If I buy an Australian Stinger GT, tuned from factory with RON91 fuel - will your tune make use of better quality fuels (RON95 or RON98, equivalent to about 94 AKI as measured in the US) that are available here? Can I vary the fuel, and the ECU will adjust as required, or do you tune for a particular fuel type and I need to maintain usage of it?

Interested in knowing what you do with regards to bench flashing ECUs for overseas customers as well. An OBD2 flashable product would be VERY interesting in situations like this (particularly if I need to get back to stock when doing warranty/service work)...

PDK shifts are so quick you can hardly even feel them, it's closer to the feeling of being in a Tesla than our Stingers in sport mode

There are a few very good reasons for this.

It's possible to change the behaviour of an automatic gearbox for more positive and faster shifting - but they'll never rival the speed of a dual-clutch transmission for the reasons of the mechanical differences between how they operate.

My sarcassim didn't relate very well in my post.

My point was, why would tuning companies move into bigger turbos, exotic fuels, when the ECU limits have not been reached? By limits, I mean tuning limits.

Everyone has ran into the power limiter in side the ECU, piggy back or tune... everyone is hitting it right now. I currently have a tune I am testing in my car, with those limits raised (I think I have all those limiters found now). Here is what I can share about the current tune in my car, anything under 50 MPH ends in instant wheels spin. If I am getting on the freeway, hammer down at 60 MPH. The traction control light starts to blink at me.

Do you see what I am getting at?

If the stock turbos are capable of 500 wheel horsepower, why abondon tuning them to that level? There is a lot of tuning tallent in this community, but everyone appears to think the stock turbo's are out of oomph, and I do not think that is the case.

So, everyone is stuck at 12.2 to 11.8 in the 1/4 mile right now. Its not becaise the turbos, its because the ECU.

You are asking a strange question ! The tune (I mean ecu tune) does bring a lot of money into the tuners pocke ! But when you install 10k usd turbo kit, big intercoolers and etc, then you are talking about big $$$$$ profits.

I know klr stinger

I'll stick with KLR Stinger for the challenge as he is already on the leader board and is only one of 3 AWDs with full bolt ons. Welcome to compete for the 1/4 top 5 still and I'll do both dragy and track come spring.

Who won the race what mods were on each car and the times?

I ended up doing a dragy 11.58 @ 120 and 11.86 @ 117 slip with tork tune, JT intake, Ark catback, UP fmic, ssr mid. Klr has had other things to focus on and hasn't made any new runs lately.

 

[jrod10]

I would be interested on knowing the outcome! You have a lot less stuff done to your car right?

 

[Tonkabob]

I just took off my ssr midpipe also and still ran 11.89 slip in 10-15 degree warmer weather than my 11.86. Seems like no change. The dp and mps don't do much. The 1/4 mile thread has everyone's mods and times.

What if Kia offered a "package" with all those parts for $10k from the factory, but with nothing different in the way of ECU tuning? Would you go for it? You'd get a bit better power due to the better intercooler, but that's about it. Your bigger turbos would have more lag, and then hit the torque limiter just as fast and your car might be 0.1-0.2 seconds faster in the 1/4 mile. Note: bigger intercooler is $700-1200, already done.

What he's trying to say is: no one's had 100% success cracking the ECU yet. They've removed some limitations, but they're still trying to find a way to run the existing hardware at 100%, while Kia's locking it down to 70% or something, for longevity. I.e. boost limits, torque limits, transmission shifting, throttle cut, boost cut, etc. Until they crack those, they can't do anything with bigger turbos.

Of course, I am making up numbers here, but just as an example, let's say Kia's restricted the turbos / engine and transmission to 70% of "max" to make sure they last 100k miles. The guys doing ECU tunes have maybe gotten to 80-85% in some situations, but only 75% in others. Until they can get that to 95%, bigger turbos won't do much, because those 75% limits will work against most gains.

We found I suppose all limits for 2.0 4wd car. And we got excellent results tuning it. We are working right now on 3.3 version of it. So far it looks good, except boost pressure on launch. On wednesday I will post dyno graphs for those cars.

Limits on the stock turbo? The Theta 2.0T in the Stinger is a new variant of, at this point, an old engine. The Genesis Coupe, Sonata, Optima, and now Veloster(or I30) N have all used some version of a turbocharged Theta and have been pushed to and past their limits on all of those platforms.

Who is "we"? What company?

ECU tune vs Piggy back challenge! 92 octane max, (no octane booster, E85, or WMI), no brake snip, any other mods are fair game. This is more of a daily driver comparison.
I'll only use the gas for the first 1/8 mile and coast the second 1/8th! Sounds easy! Any takers? Any dragy valid run counts. (I typically run 94-95 MPH in the 1/8th so will lift when my HUD shows 95 MPH.
Track is closed for the next month, forums are pretty dead, let's liven things up!

Arent you able to launch on higher RPMs? So wouldn't that be equivalent to the brake snip for piggybacks?

Just a little higher like 200 rpm and 0 psi but thats part of the ecu tune. Its about 1/100 th the advantage of brake snip.
Gotta cut me some slack, i have to coast for 1/8 mile!

 

[Tonkabob]

No takers i guess. The 1/8 mile gas 1/8 mile coast time is 12.2, 12.3.

So for my wife’s daily driver, she wants some more power and I figured a piggyback system would suit her just fine. Now is there any reason why I shouldn’t go forward with that?

Leave JB4 on map1 and enjoy tons of extra power with a very low risk conservative tune.

...but once you try map 2 or 3, you won't want to go back!

 

[JBoogie]

While the comments on the jb4 sound nice can anyone explain all the issues that are surrounding it within this forum? There are so many different threads that I said f*ck it and moved on.
