Did my first launch w/jb4 and TCU tune

[ICE_TT_3.3]

This post is more or less just some of my thoughts from my own perspective on what basic mods can do for this car and my initial thoughts on the overall performance.

I finally got my spark plugs, jb4, and Tork stage 1 TCU installed last week and got the chance to do a few launches on map 1 with Shell 91 octane. I’m running some crappy stock sized GT Radial tires (carmax selected lol) square setup and I brake boosted until around 2500 rpm on launch and got the tires to peel out pretty good. I forgot to catch what boost I was launching at and didn’t get any logs this time around or record the launches with Dragy.

All in all the car feels amazing in just map 1 and combined with the torque management reduction and shift points from the Tork stage 1 TCU. My next step is to fill up with about 5 gallons e85 and the rest 91 octane from a different gas station and run on map 2 or 3 after checking im in the clear and get some recordings on Dragy and see what I’m hitting for boost on the launch. I’m not currently running any aftermarket intakes and only have a catback exhaust in addition to the piggyback and tcu tune.

Comparing the Stinger to some other decently quick cars I’ve had in the past, it definitely feels the quickest and also easiest to mod to get more power per dollar. The launch on map 1 was not quite as violent as my 2800 rpm stalled Charger 5.7 (I know the slower v8 Charger) which definitely was slower than the Stinger post launch, but I’m sure it’s a combination of the bad tires currently installed and map 2+ is probably going to be a lot harder launch as well. The Stinger also feels almost as planted and fun to drive as my ‘02 Firebird T/A 6 speed which was obviously a lot lighter and a 2 door rwd car.

I’m excited to try out e30 and map 2+ with the Stinger and get some logs and recordings here soon and eventually get new tires, some intakes, and the CPI kit installed.

I think you will be pleasantly surprised.
With E30 on map3 and a Lozic TCU I went from 13.2@108 to 12.5@112.

Mid 12s would be nice and the fastest I would have ever been, but what does it take to get these cars in the high 11s as I thought a tcu tune paired with more boost via piggyback or ecu tune would result in at least low 12s? I’m at about 1000’ elevation where I live and drive my car most of the time.

ECU tune or CPI.

Tcu and meth as well

CPI and intakes are next on my list. How much am I missing out right now with stock intakes? Guessing a tenth or two within first hundred feet of launch.

My times currently are 12.5@112 with the stock airbox and K&N filters. I have the JA snorkels as well.
A little birdie told my wife that for my upcoming birthday, I wanted the BMS intakes. If I get them, then I will be able to see the difference in times. I don't plan any more mods until then so should be a good apples to apples comparison.

Will be a good test to see how much the larger filters work versus the paper filters in stock air box with scoops.

Did you build any kind of boost on launch? lozic has told me that his TCU wont build boost at all unless his boost ready feature is enabled for the entire RPM range in the ECU

My Lozic TCU has the launch control torque limits disabled. It is a bit of a learning curve to get the right amount of boost without getting too much.

What happens specifically when you get too much? does your car bog down at all? or do you just spin spin spin?

I have AWD so I don’t worry about spinning at launch. One time I gave a little too much boost and spun the rear tires a couple turns before the green, front brakes held so no red light. Don’t want to do that again, transfer case probably didn’t like it, but no damage.

did you ever give it too much boost while you where at the strip? cuz my Tork TCU works the same way your lozic one does but it still has the safety's enabled I bet, as the first time I went to the strip in this car, it would fall flat on its face on launch because of what I can only think is too much torque being generated, because if I let off the gas then jump back on it, it goes like nothing happened. This only happens at the drag strip because of the extra grip to the tires. On the street it will just spin the rear wheels if I do it.

Want this tork tcu real bad coming soon. Did you ever get the problem resolved? Are you Awd or rwd

IM AWD, its also Not really a problem, its just my car generating too much torque so the safety systems that he has enabled are triggered, and it only happens on the drag strip because of the added grip.

This is what behavior I’m seeing from mine but on the street. After the tires spin while break boosting and I release the break pedal and go WOT, it kind of bogs down for a split second and then takes off. I had the same thing in my Charger and it pulled a 4.6 0-60. I may get some comparison videos of both the Stinger and the Charger to show where the car bogs down in both on hard launches. The difference with the Charger is it would throw all the spare coins or anything loose in my dash and was a much more violent launch at only 2800 rpm which I don’t think was even close to the full torque the car was making at the time which was also most likely less than the stinger. So I have no doubt this car will out launch the Charger just a matter of getting the launch down better and maybe better tires in my case along with some aftermarket intakes with larger filter surface area.

what RPM are you releasing the brake at? Also, you should know that the RPM gauge is about 150-200RPM slow when using launch control, meaning that if you are letting go at 2600, your engine is actually at 2700-2800. I have tested this with my car using the RPM gauge on the JB4 app as well as using the Torque pro app and they both say the same thing. When using the Factory LC, the car will be at 2100ish RPM when the needle is still moving around the 1900ish range, and using the full tork LC, when the needle hits 2400, the car is actually between 2500 and 2600rpm. I cant get an exact number because the rpm just shoots up that damn fast, but for a stage 1 tune, I feel like even with a completely stock car otherwise, 3000rpm is just too high and will trigger consistently. the limit should be between 2700-2800 at MAX, and that will still probably trigger it, but it will vary by car. last time I went to the drag strip a few weeks ago, I was using the RPM warning light in the JB4 app as a trigger to launch, so I would release the brake as soon as the light flashed. I tried 2300, worked fine, 2400 worked fine, I wanted to try 2500 but couldn't get another run in as they had to prep for some honda exclusive event. Its what I will be doing next time I am there for sure though.

 

[ICE_TT_3.3]

I think I let go around 2400-2500 rpm. That makes sense. I think I just need more practice for sure.

 

[ICE_TT_3.3]

Here’s how the charger launched and the stinger does something similar where it cuts power for a split second and then continues on. It may be normal and I just don’t have the experience with racing cars to know.

Today at the track what I did was stage, when I see the first yellow, I floored the gas and on the third yellow I let go of the brake. My times were more consistent, my best was 12.366@113mph.
