2.0T JB4 Tuner help

[Stingers4life]

Hello, I have a 2021 Kia stinger GT-Line 2.0 and I wanted to buy a JB4 Tuner. I did a decent amount of research today from reputable sources (and this forum) and really want to buy one. I know how to install the JB4 tuner and I was going to have jiffylube replace the sparkplugs with the spark plugs that are made for my model car from the k8 stinger store. My only concern is I truly don’t want to ruin my car in any shape or way....I’ve read some posts that the JB4 can make your car knock, idle hard, slow launch, etc. I just am looking to gain a little bit more performance in my car is all. Do I really need the wireless Bluetooth set that it comes with? I’m not looking to race or anything involving more performance modifications I just simple want to go a little faster. I’m not interested in setting exact MAPs and all that stuff. Thank you!

Bluetooth is worth it. Changing maps and data logging make it easier. Knock occurs when your octane can’t keep up with the map you’re on. Send logs so we can evaluate if you’re running safely.

Okay thank you, if I am to purchase this tuner and install it and all, before I drive it, is there any presets I should put the tuner on first? I’m just trying to avoid as many errors as possible. If this helps, I use Sunoco 93 octane.

Change your plugs or gap the stock to 0.022. The map is already preset to map1. Higher maps require higher octane.

Okay so if I change the plugs to the HKS performance plugs for the 2.0T and use 93 octane will that work for me? I don’t plan on using higher than 93 octane so what map should I be on

 

[Stingers4life]

also, is MAP 1 less performance than MAP 2?

 

[ChaneRZ]

When you have everything installed, do a log on map1 and we’ll go from there.



Map 0: JB4 disabled
Map 1: 4psi over stock peak tapering to 2.5psi at high RPM. Default performance map suitable for all 91+ octane fuels.
Map 2: 5psi over stock tapering to 4psi at high RPM. Suggested for 93+ octane fuel.
Map 3: 6psi stock tapering to 5psi at high RPM. Suggested for high quality fuel including unleaded race gas, ethanol mixtures up to 30%, or high quality octane booster like Torco or Boostane.
Map 4: Up to 7psi over stock. For use with unleaded race fuel and/or E85 mixtures up to 30%.
Map 5: Up to 7psi over stock but without top end taper. For unleaded race fuel use and bolt on modifications. May not be suitable for E85 mixtures due to high fuel pressure dropping. If using this map on E85 you should be experienced at reading your own logs and evaluating ignition advance and fuel pressure.
Map 6: User adjustable map. Enter value of boost over stock by RPM on user adjustment page.
Map 7: Progressive WMI (water/meth) map. Increases boost as a function of methanol flow & methanol boost additive. Holds boost low until WMI is flowing to avoid tip-in knock, and reduces boost as a function of WMI flow in the event of interruption like running out of fluid, leak, or component failure.
Map 8: Valet map, runs around half as much boost as stock.

Okay great, thank you for this wealth of information regarding the Map(s), and also your time to help me with the logs in the future. I think my last few questions for now would be:

What are the potential bad effects the JB4 tuner can do to my stinger? For example, is it common to kill the battery, stall the engine, blow the HKS spark plugs, etc what are the possibilities for any event like that to happen?

Do I have to gap the HKS spark plugs in the 2.0T stinger? If so, to what number?

How much of a gain on horsepower and torque can I be looking at in just Map 2 alone?

You’ll blow your spark plugs if you didn’t gap them. .022-.024 is the proper gap.

Significant gains. For exact hp, you need to dyno your car.

WOULD VALET MODE TECHNICALLY SAVE YOU ON GAS IN SOME WAY? sorry for caps but I'm lazy af.

HELLO SIR! I see you have a flex-fuel kit. would I need this to run e30? I want to try it out first but not 100% sure if ill f*ck up my car by just adding this gogo juice without getting the flex fuel kit first.

 

[ChaneRZ]

You don’t have to have the Flex fuel kit to run E30. It’s a sensor so that you know what exactly your mix is. You don’t have to guess how much E85 on your current fuel.

 

[Angeski]

To be clear, only mixing gas is my option since I cant run e85?

 

[ChaneRZ]

You can’t run full e85.
