3.3T Ecu tune

[joschneider]

Tork Motorsports is saying that they'll have OBDII flashing available "hopefully" by Spring. If they do it, I'd be down to get it.

They mention still having to mail your ecu off once and then you can do OBD2 for different maps. Boo haha

We'll see for sure when it's out, but it sounds like you're right.

Anyone see tork hit 651whp with a 100 shot of nos?

Yeah, just read that! Pretty dang awesome. The dyno chart looks perfect, too.

I want to know what he's doing for the additional fuel. Honestly, I'd kind of rather do nitrous over a big turbo upgrade, seeing how the ECU tuning has not matured as much as I'd like to see it by now..

Could you elaborate on that? You mean like not much progress being made or what?

I feel you there. I can’t real express how much I’d rather do something like a 20psi stage 2 tune once they get it buttoned up. But I also love having this super nice warranty. I’d like that back end flash a lot too but again a flash is a flash we will see how things go over the next year or so and maybe Next winter I’ll just do both ecu and back end to have everything that makes the car happy. But I’m also incredible happy with where the car is now so who knows

Specifically, a very limited number of ECU flashes available, and not being able to break past a number of barriers...such as max boost with big turbo upgrades, the ECU (or some other component) can still override the diverter valves when hitting a certain boost pressure. Some have reported transmission shifting problems, likely due to TCU logic safety algorithms. Also, the fuel system is constrained - no upgraded low pressure pumps available, nor are we able to upgrade the high pressure pump, leaving excess fueling needs to be filled by meth injection.

So far ECU flashes have only really changed the same things as piggybacks, that is, fuel and ignition timing values, throttle mapping, and not much else. What about valve timing control? Significantly increased max boost values? TCU logic changes resulting in faster shifting? Changes in LC parameters? It's only just now that Terry at BMS is beginning to get wastegate control.

Simply put, we still don't have a comprehensive solution for a big turbo upgrade without crazy additions like race fuel, meth injection, piggybacks combined with back-end flashes - and even then it still has problems. That said, if you want to use pump gas, you cannot upgrade turbos. And, we still don't even have OBDII flashing capability....

Found this on the Stinger forum just now. Wow!

Here is Kagantuned’s results so far. Only his stage 1 tune with absolutely no other mods yet.

awd?

Yes, here is the rest of the quote...

It was a little uphill and he spun all 4 wheels so he’s expecting 3.6-3.7s with better traction.

If he is doing that all with the tune and without the brake snip mod, I am impressed. Our launch and TCU torque limits are our platform’s barriers to faster times. If he found a way to get around those limits I am very interested to learn more.

no freakin way they are getting a 3.8 0-60 with ZERO MODS and uphill?!? Nearly an entire second faster than stock spec. Bizzare to me! imagine what its running with full bolt ons! I’m no car brainiac but that seems very impressive to me.

i still wanna see a 1/4 mile as well and all numbers on rwd too

 

[Toddasaurus]

Maybe his stinger is a unicorn, and was putting out more power from the factory because it is a one off freak engine. Lol, idk.

If results like these can be repeated from other owners I'll be super impressed. Even so, I really think he's just pushing the timing further than other flash tunes out there. He's using 93 octane, but he said his current tune is not meant for 91. But still, he must've done something to launch harder...

I want to see his dyno numbers. That graph looks too good to be true for just a tune

Numbers are cool but the thing to really look at is the curve. Like Tork pretty much help 500 lb ft of torque across the entire power curve. And it head a steady strong climb up to 650hp Insane for our cars That car has some good potential to run in the 10s if he can get the car to hook off the line

I don’t think horsepower or torque are really limiters for our 0-60 and quarter mile times. These cars have sufficient horsepower stock to get us into the low 4s in terms of 0-60. But its the ECU/TCU and soft launch control that is holding us back (especially 1st and 2nd gear) and slows us down. Genesis/Kia have put those restrictions in place for warranty purposes. So the tune could probably add as little as 50-60 hp and still pull a sub 4 second 0-60 run if the nannies were removed and it permitted a more aggressive launch and retains more boost during shifts. I’m still skeptical of this time, but I doubt the dyno would tell us the story. I would want to know what the tune actually changes.

Interestingly, Bimmers have done it, but they are notably less reliable...The new B58 and S58 platforms are going to break alot of hearts on the street.

Oh yes. The B58 is no joke. That thing can be a monster without even touching the internals.

Just heard back from PRESSERTech after I asked for more details about their tune.

When asked about boost and AFR's, he replied..

Boost is around 15-20psi depending on environment. AFR aim at full throttle will be around 11.5-12.8 :1 , environment dependent. Hope that helps.

Scott also told me that any re-tunes or going back to stock will come at no cost, other than shipping.

I'm leaning towards the PRESSERTech tune primarily because I can't get Tork to respond to any of my emails. I have no doubt that the Tork tune is great, but, I'd prefer to go with a company that takes care of their customers, and responds to their emails at least.

Let us know how things go with Pressertech. Interested to hear your perspective on that vs the JB4.
