It goes in to spot #4 then. Email me for the firmware with that input enabled for the flex fuel input.

from A recent dyno run we ran maps 1-2-3-5 to see how the car behaved and what power was made learning more about the car how ever the Bluetooth disconnected on map1 and map2 runs not sure why this happened but not as concerning as the car only making 345hp and 424tq max and that was on map5
I have attached the logs i was able to get would love any advice

That seams low for map 5. I made 375whp on map 2. What kind of octane you running?

[u/tonyv1990]

91 and yeah it only made 328 on map 2 im getting more worried now ha ha

Got my catch can today and had it installed in 5 minutes... Thanks Terry!!

Hello Terry,

I have a few questions that I want to verify with you before I install the JB4 to my 2019 Kia Stinger GT AWD.

1. I ordered the denso spark plugs from your site, but will I need to install those for map 1? I am trying to take it slow first then move on to map 2. I am seeing different answer to where map 1 will be able to run with the factory spark plugs. Once I am comfortable with map 1, I was planning to install the denso spark plugs with gap of .22 then move to map 2.

2. Is it best to be in v8 once I install my jb4?

3. I don't want to go to a Kia dealership to get the spark plugs installed and I also don't trust myself to intall it myself. Do you think it is a good idea to find a good mechanic near my area to install the denso spark plugs? (Even though the mechanic may have not dealth with a stinger before.

4. So map 1 needs to use 91 octane and map 2 needs to use 93 octane?

5. If I ever decide to go back to stock from the jb4 tune then all I have to do is take the JB4 plugs out of the vehicle but the denso plugs would still be in the car. Will it be okay for the denso spark plugs with gap .22 to be in a stock stinger GT?

Thank You Terry

1) Sometimes map1 works on stock plug gap, sometimes it doesn't.
2) Doesn't really matter. No reason not to run the latest firmware, though.
3) There is a DIY video somewhere around, anyone can do it. Takes an hour or two the first time but maybe 30 min the second.
4) You can run map1 or map2 on 91 octane.
5) Not an issue

Hi Terry (and everyone).

This is all regarding a '19 GT1 AWD, running on map 2 with 93 octane.

Last week I noticed some erratic behavior on acceleration (anywhere between 1/2 to full throttle), the car would occasionally 'hiccup' or have a quick drop in power before picking back up. Acceleration was also less linear than it had been. This happened in all drive modes.

I thought it might be bad gas, so I went to a different station for the next tank. Unfortunately, the same funky behavior continued. I tried flashing to v10 from v8, but the checksums didn't match so I went back to v8. I also started using the app to watch gauges and monitor boost while driving to see if I could figure out what's going on.

Whenever I make more than about 10 or 11 pounds of boost, the JB4 display freezes! I try to run logs, but the system will freeze and then record 2 or 3 log sessions rather than just the one. I successfully flashed to v10, but the same thing is happening.

When I run map 0, the car runs a bit smoother but the JB4 still freezes upon hard acceleration.

Any advice on what may be happening, or has anyone experienced similar behavior?

Thanks!

Jeff

Would you be able to post any of the logs you captured?

I saw that on our development car once when a factory spark plug was damaged. It would send a jolt back through the electrical system that would cause the JB4 to disable itself for electrical safety purposes.

More recently had a similar issue with a WMI customer and a faulty FSB kicking back an electrical surge.

It's likely something electrical or plug related.

[hamburger1971]

Thanks, Terry. I have the replacement plugs from you guys. You think that could still be it, or can you think of another weak spot in the electrical system worth checking?

Hi Payam. The logs seem to be pretty random, but I'm posting the recent few for you to see. If you think it's worthwhile, we can take the discussion offline, hamburger1971 at hotmail dot com. Some are from map 0, some are map 2 - there wasn't always rhyme or reason to when it recorded, and even when I hit 'start logging' the system might not have stopped when I asked. If there are specific scenarios you'd like me to try and get please let me know.

Thanks,

Jeff

Only if one was damaged during install or if there was a coil issue. Another test might be to remove OBDII cable all together to see if you can recreate the symptoms on map1.

At any event just email and we'll help you that way, terry@burgertuning.com

Good evening. I just got the JB4 installed on my 2016 Optima SXL (2.0T), map 1 runs just fine, tried map 2 and it defaulted back to map 0 half way through a 3rd gear pull. Just changed the plugs to the M45XL HKS plugs, running 93 octane. It seemed to hesitate right before (or maybe during) the switch in maps. Any help you can provide would be greatly appreciated. Hopefully the day to log uploads.

Here's a log from map 1, I'll adjust and take another log on map 1 in a little bit after the adjustment. Seems like it stayed in map 1 the whole time? Not sure if everything else looks ok.

[Terry @ BMS]

Log looks OK, next log do something more like a 1/4 mile style run with shifts.

Any info on the self learning map for the stinger?

[spyders03]

Let me know if you need a longer log, didn't have a ton of room this morning. Thanks in advance, we all appreciate your expertise!

P.S. the JB4 in map 2 feels AMAZING!

We haven't released one yet, but plan to in the future.

Timing movement is a bit odd but not sure if it's a logging thing or how it's actually running. Try to grab a couple more logs for comparison.

Hi Terry;

I'm new to this platform and had just received my jb4 w/ BT dongle for a 2019 Stinger GT using stock plugs / stock gap, 91 octane @ 2K ft elevation. Your replies above answered most of my questions. But I got 2 more:

1. Do I need to use/connect the OBD2 plug in order to get the maximum benefit of Map1 & 2? or is the OBD2 plug just for monitoring gauges on the phone?

and

2. If I just got the jb4 (brand new), do I need to worry about any firmware updates at this time? or am I good to go as is - just plug and play?

Thanks.

Chris

Here's a 1/4 mile style log. Roads were slightly wet so there was some wheel spin down low
