Drag/Acceleration Mods to improve ¼ mile times and unofficial track thread

[Kato_the_kia_stinger]

If you are asking about the launch part, yes, 2500 RPM, 3.5 PSI and 1.75 60 foot is all in the tune.

The snip part is cutting the ECU brake wire but the switch is left connected when using LC. The switch prevents normal LC.

Is there a drag strip near you guys? You have awesome and consistent Dragy results, but I’d love to see slips this season.

Tonka go to the drag strip, never... LOL

If anyone goes to the drag strip, its going to be him.

Here are the first few TNT dates:

03/15
03/21
04/04
04/10-11

Now, that is our rainy season, but hopefully we get a good day on one of those TNT dates to reset the record.

Also, that gives me another month to make the car even faster but that will also put Tonka into a spot that he has to get more gear to run these times. I think a coat and shoes are required at 11.49. And something about a cage at 10.99 or 10.49.

Cat is out of the bag, because I want to see Tonka run 10.99 at the track this year on the stock turbo's. If we can manage that, it might be a record that stands for a very, very long time.

Oh man, I hope the weather is friendly! And do you have any idea how excited I am to hear “11.49” and “roll cage” and 10s?!?! I cannot wait to see the top few best slip times destroyed... even if I am one of them. This is going to be a FUN season!

 

[Tonkabob]

11.49 is just a jacket. I better get that ordered.

 

[TorkMe]

Thank goodness

You had better get that ordered, and gloves. The jacket looks weird without the gloves.

With new players as well. I might add.

indeed. We have 11 guys about to get Motec M142s so if anyone sets a record to stand...its going to be 1 of us

 

[Tonkabob]

First to blow engine likely.

I like stand alone systems but the factory turbos are the factory turbos so it will be interesting to see if Motec provides anything useful for those applications. Where Motec is more useful is when combining DI & PI, switching to pneumatic wastegate turbos, working around internal DME limiters that flash tuning can't figure out how to remove, etc.

A lot of assumptions are being made with this reply. Lets not assume what the factory turbos are or are not capable of until someone maxes them out. Again you're making assumptions on what can or cannot be done with the factory ECU. At this point in the Kia Stinger tuning development we feel that the potential is unlimited with the factory ECU. Outside of adding secondary controls for MPI or water meth. We are confident the factory ECU will be just as efficient as the MOTEC when fully mapped.

Most of us moving to Motecs are not going to be stopping at factory turbos, so its tool for getting beyond the current capabilities of ECU Tuning.

I can’t disagree there. Good luck and drive fast.... I mean safe. I mean both!!!

Makes sense but so far even those those running larger turbos have not maxed out what the factory ECU + JB4 can do. It's going to take a really unique set of requirements to justify the cost and time investment of a full stand alone for the platform IMHO. Glad someone is doing it but to hear 10 people are getting it makes me think at least half of those don't really know what they are getting in to.

 

[Terry@BMS]

I'll give you the benefit of the doubt and just say I think you misread my post.

 

[Terry@BMS]

So, I stand corrected (thank you tonka) the 11.39 draggy is all tune, no JB4 intervention or help. Also, no brake snip or assistance for LC either. This was all 100% Tork Tune!

Even so he's benefiting from JB4 WMI control and JB4 data logging. He happens to be running the WMI in a "spray and pray" format currently with no active safety but that's a long term recipie for broken parts. We'll talk him in to enabling some of the WMI safety systems down the road.

My understanding is that WMI safety is only on map 8 which I can't run.
I'm all up for more safety but don't think it works for me yet.
I will say the data logging is quite nice.

JB4 data logging sucks, because we have no idea what values you have programmed into the sensor settings.

Great example:

Tonka's boost levels. He some how manged to hit 36 psi, but the sensor only reads to 28.8. It was not until Tonka pointed this out, that you had to adjust it. Makes me wonder what other "sensors" or "data" you are collecting is accurate.

Last, with the JB4 controlling his water methanol, I have no option of that to trust what your logging, because I cannot plug in my emulator or factory scan tool to see whats actually happening. So... prey and spray you say? Without accurate logging, its more like... "just prey that we are getting accurate data".

What needs to happen is for us to wrap up the JB4's "flash mode" programming which would change the safety systems so instead of reverting to map0 it reverts to map4 (less boost than your flash), and that would also enable a flow based safety so if flow dropped below the floor for more than a second under boost it would revert to safety.

Sorry but per usual unable to follow you. As of v12 firmware boost display was adjusted by request of Tonka, x0t1, and others to reflect 10% higher. On my car boost now reads ~10% higher than my mechanical gauge so I'm just waiting for the next round of customers to turn up saying it reads too high now. You can follow the boost scaling discussion and details here: JB4 boost readings still seem low

Not following you on "36 psi" but you might be referring to one of the internal fields ecu_psi not being scaled up to match actual boost due to a change with the logging app? If you or anyone else is aware of any logging issues feel free to detail them and we'll promptly address them.

Also the MAP sensors are 3bar, or around 43.5psi, at around 4.6v. Technically it can read a little higher. And the "absolute boost" depends on what the zero point is. e.g. in cold low DA weather you can read more than 29psi gauge pressure.

I don't want to follow any of your lies, lol. I have a lot of logging app complaints, but I quit trying to post them because you start to belittle and make childish comments about me, my customers or my manners.

Um, no shit dummy. All automotive ECU's log in absolute, but that it not what we were logging, we were logging you faulty scale for the boost sensor. Baro changes may have .5 psi difference, but you should never go over the 28.8-29.3 scale that is set. This tells me one thing, you do not know how to scale the map and boost sensors on the Stinger.

See, this is why I don't interact with you... you simply cannot say, "we have no idea what the scale is for the sensor, so we have to adjust it by trial and error". I would appreciate that honest answer more so then you trying to outsmart me when it comes to the "DME" (again... we are not on a BMW forum) inside of the Stinger. This makes me think, several of your other "logging" parameters could be wrong also.

Here is the deal, I have seen your rants about "trusting me" or our "ability" to tune the car or build a back end flash. You have no real tuning experience, and sadly, it took the community 18 months to figure it out. So, as we move forward, and you make some fantastic failed attempts to take more control away from the ECU, I will be cranking away at getting more of the ECU mapped, and continue to run faster and quicker in the 1/4 mile.
