Tork Backend Flash

[WildBill]

Saw this on FB last night. @TorkMe is looking at providing backend flashes to piggyback users.

This would take care of a myriad of issues piggyback users face which can't be overcome without flashing the ECU. But this backend flash does not adjust the boost or timing leaving that to the piggyback. This way you can still adjust your map on the fly for cruising, spirited driving, kill all, 93 Octane, E40, WMI, etc.

I think this is a brilliant move on Tork's part. Embrace those people that want to use piggybacks for their own reasons and work with them. The price is pretty good if you ask me, after all, they have to do the same amount of work to give you the flash. Cheers to Tork for moving the platform forward some more!

Here is the FB Post.

KIA Stinger 3.3 "back end flash"... who wants one?

Now, some of you may be wondering... what is a back end flash. Well, that is a flash you use in conjunction with a piggy back or some other type of signal modifier. I have acknowledged that the Stinger market is not going to get rid of their piggy backs, so we have made the decision to fall into the fold (or something like that) to get your guys cars running optimal with a piggy back.

What will our back end flash address?

1. Shift improvements. We will adjust shift timing and stop ignition drop. Thus speeding up the shift recovery, this has been good for .2 seconds in 1/4 mile times.

2. Increase torque limits, this should stop the throttle from getting closed on shifts. We have seen a lot of piggy back datalogs with the throttle closing on shift or the throttle closing in the higher gears due to torque limits being exceeded.

3. Tops speed limiter increased for those who have a 135 MPH limiter we increase it to 170 MPH.

4. Target lambda (air fuel ratio) will be set to one of the selected options you choose in the menu when ordering your tune. We will have 11.4/11.8/12.0 as options for your desired AFR ratio's. Custom AFR/Lambda targets will be an additional charge.

5. Stop cat over temp protection from kicking in and raise the fuel correction for turbine temps. We will have catted and catless options for these correction limits.

6. o2 code for catless/race cars cat delete.

7. Turbo speed limits increased (calculated not actual) to allow the full ignition spark delivery, so you no longer have to gap your spark plugs down to the .021 or smaller to get the piggy back to work properly.

8. Increase in coil dwell time to aid in proper plug gap and reduce spark blow out. This will allow for larger spark plug gaps to be ran without spark "blow out".

9. Increase max air flow limits... to stop the sudden "dead throttle" from happening when pushing the limits of the piggy back boost levels.

10. Low fuel torque limits increased to standard limits, so you can run at 1/8 of a tank when at the drag strip. This will not stop the factor fuel system from running out of fuel, or the fuel basket from getting sucked dry (fuel basket is the reservoir inside your fuel tank).

I need some feed back from the community if this is something they want us to offer. Starting price would be $495 (damn steal) plus shipping. With options, it would price out to $695 (custom requests from customers). We would not set or change anything in the boost management or ignition management, due to the piggy back controlling those parameters, but we can address all the limits that currently hold the piggy back from being utilized to its full potential.

Please let me know if you would like to see this as an option for the 3.3TT Stinger models.

Thanks,

Tork Motorsports.

Ummm, yes please! Price is good too. This is what we've been waiting for.

Good in theory for those outside of warranty to remove the speed limiter, rescale the mapping so it's closer to actual output making the JB4's job easier, theoretically improve high boost shifting, etc. But I don't have a lot of confidence in that tuner so I'll have to see customer logs of exactly what is being changed before I can suggest it.

 

[WildBill]

The bickering between you two is nauseating... Haven't you said that we need back end flashes to overcome the car's limitations and get more out of the JB4? Haven't you said that you do it commonly in the BMW platform?
Yes, we know about the potential warranty issue. It is not that much different than using your product. Yours you can remove in 30 minutes at home. With the ECU tune you must send the ECU back to Tork and get it re-flashed back to stock. 3 days if you are in a hurry.

BUT EITHER WAY THE FACT THAT YOU WERE RUNNING HIGHER THAN NORMAL BOOST IS DETECTABLE BY THE DEALERSHIP.

Am I wrong in any of these statements?

 

[Socalstinga]

saw this on FB too, and Tork's response to me was that it was being offered as a cost effective option for those with a piggyback. I already have a piggyback and would rather do a full ECU tune. I'm still waiting on the sidelines for a good tune that can be applied by someone more local to socal, I can't be without my car for 3-5 days. I was set to pull the trigger and make it coincide with a few days I was on vacation, but I can't quite get a straight answer regarding the power increases. website says up to 100whp, one person who answered the DM to tork said 50-70 whp, and another said 70-100. I just want to know what I can reasonably expect to gain, and it sucks b/c it appears as if a lot of other parameters have been tuned (which is awesome and the whole point of a ecu tune).

 

[Terry@BMS]

I fully support back end flash maps for those looking to modify more seriously but that doesn't mean I support all flash tuners.

Unlike a piggyback where you can easily identify what is being connected and what is being changed, there is a lot of trust is involved in loading and running a flash map, which could have countless changes many effecting long term safety and reliability. So choose your flash tuner carefully. My opinion of Tork is well documented to anyone reading the various Stinger FaceBook pages. There are plenty of other more reputable Stinger flash tuners floating around and I'm sure we'll see more in the future. I'd suggest most wait for better options.

In terms of detection with a well designed piggyback all values must mirror factory for the tuning to work properly and thus is not detectable. On the other hand with a flash map true modified values are stored across multiple vehicle modules beyond just the ECU, and are thus are easily noticed.

In my opinion those who are looking at flash maps, back end, or otherwise, are usually heavily modified beyond just tuning and thus not concerned with warranty/lease returns anyway.

 

[Socalstinga]

@Terry@BMS I can't seem to find any other Tuners that would work on the stinger. All I've seen so far is Alphaspeed, Tork, Presser, and Lap3(although none of it is in the states other than the piggyback).

I thought actual boost numbers were recorded by the ECU and actual torque values were stored by the TCU. If they are too much higher than stock a dealer would know that SOMETHING (hardware or tuning) had been done to the car and it was not stock prior to service.

I agree, it just sounded like this was an argument not to get a back end flash map.

True with any flash, false with any properly designed piggyback.

The price is very good, if you ask me. I hope we will soon see good results using this kind of combination.

It sounds interesting. However, the biggest (by FAR) piggyback out there for Stingers is jb4. On FB, Tork (John) last week basically swore on his family's life that he'd never work with Terry, ever, to his dying day. Yeah, THAT gives me confidence that he'll help customers stacking a jb4...

Two of Torks customers stack with jb4 now and he helps us out. Plus the base tune is pretty straight forward so most the tuning and issues will be on the jb4 side.
Terry has also been helpful with the stacking. Only thing in common Terry and John have is they both like fast Stingers.

Sure, but.. you guys are also clearly "Team Tork". I expect John to go absolutely apoplectic the first time someone tells him Terry said it's a problem with the tune, not a jb4 issue..

I'd just pick up 18 psi stage 1 for $800 now ($100 off) and run this as your daily and use jb4 for boost by gear or when you have good gas add a couple psi or do iat spoof in the cold. Runs on 91, cleaner timing, safer first gear afr.

 

[Tonkabob]

Looks like Tork also just figured out LC. Just posted a video hitting 80 throttle, which is about 90% on Torque apps 1-89 scale and 4 PSI. Maybe he will toss that into the $500 flash base map deal for anther $100. 4 PSI, 50 or 60% throttle opening fully by 10 MPH would be very fast and no spin for the AWDs.

 

[xot1]

Anything for RWD?

 

[WildBill]

Tire smoke!

 

[Tonkabob]

Anything for RWD?

His car is RWD so its for both. You just wont want much more for RWD unless you got some serious tires.

 

[Terry@BMS]

I hope the fix is to change the launch mode "boost target" (load target) and not just disabling the throttle safety. Load it up and lets see what it can do! For your AWD since it can't run "send it" brake boost without spinning maybe it will wind up being a good compromise.

This seems like the perfect solution for what I want from my Stinger. Definitely interested.
