Burger Tuning JB4 for Kia Stinger!

[StungBlueGT2]

The FUD setting is only effective for partial throttle oscillation.

Stock intakes would reduce power/boost potential, so would certainly have an effect. As would running a lower boost target in the engine speed range effected.

No luck on EWG control yet. IAT control might be useful though.

The FUD setting helped, but oscillations are still noticeable with firmware 6-8. Could the v6 firmware update “less throttle closer during shifts” also be related to the oscillations? Can that be disabled with FUD Bit controls?

So any bolt-on upgrades that increase power/boost potential will cause oscillations? Wouldn’t everyone with intakes or power adding mods have the same issues?

Also, changing to a lower boost target doesn’t help. Same boost issues on map1 as map2.

Nothing seems to eliminate the oscillations except reverting back to firmware 4 or 5. Unfortunately then you lose the double-PID fuel control and other great features.

IAT control would help in warn FL weather? I thought that was for helping people in cold weather?

Feel like we’re close to resolving the problem and hopefully just one more setting away from perfection!

Email in a log on the previous firmware without the issue, and one on the current firmware with the issue present, and I'll see if I can track down any other differences. You can switch back and forth to get the logs in the same testing session so all other conditions are similar.

@Terry@BMS I have an IAT wire.... if I install it how do I get it to work? Do I need a special setting or something? Any help would be appreciated?

Terry, some guy on the Korean forums asks why sometimes JB4 logs show the 0-100kph and sometimes not. How is the function implemented?

You attach the wire like this. How you use the new logic depends on what needs to be done. I'd have to see a JB4 log to offer advice on that front.

Ok thanks please correct me if I am wrong. The IAT wire I got from BMW I install that to the number #9 plug on the JB4?
Then I tap that wire where? Then I posi tab the #2 wire on the JB4 Clip that goes to the sensor? So i dont tap the oem IAT clip?

It's 1/2 of a fuel wire kit, the short wire with a resistor in it. And it goes entirely on the JB4 harness per the photos above.

I’m not sure I understand the need for the extra IAT wire? Doesn’t the JB4 already read intake temps? I get a readout from mine... (maybe because I have the OBD hooked up?)

There generally isn't a need. In some racing situations (specifically when it's really cold and you want to run a lot of boost) it's useful to have the JB4 adjust the ECU observed intake temperature so that extra wire gives the JB4 that control.

It's not need to read IAT. It's to able able to augment the signal to higher reading to allow for boost and timing table modifiers to be used to our advantage.

Thanks for the help! I am content. For now.

Am I the only one who put the "this product is for racing only" sticker up? I thought it was cool to see it. Lol

Sort of off topic. But after many 1800+ mile road trips. My engine bay is dirty dirty. Anyone have any suggestions on how to clean and keep it clean?

Micro fiber cloth and I personally use all surface cleaner detailer by McGuire. You could use armor all for the black plastics. Don’t use a water pressure gun at a car wash like the Honda guys lol.

Thats the one buddy!!! That is so amazing I once tried to clean my daughter with that once after changing a poopy diaper, I used that and micro fiber cloth instead of baby wipes.....The wife almost killed me. I used that to clean the whole interior and the engine bay of the car. I wish I could post pictures if it was not winter time and snowing. This summer I will make a video on cleaning the car.

An APC (all purpose cleaner) diluted 5 to 1 in a spray bottle a brush or microfiber towel will do the trick. Also DO NOT use armor all on the plastics.

Took a few runs last night in the chilly 45f temps we have around here lately.

Mods: JB4, BMS Intake, BMS Prototype Intercooler, 93 octane, stock rims/tires, stock exhaust system, no WMI, full weight, etc. JB4 set to spoof intake air temp up around 30 degrees.

I'm really pleased with the trap! Had boost set to -4psi in 1st which helped off the line but with 1WD on stock tires traction is always the enemy.

What does spoofing the air temp do? Is that with the IAT wire?

 

[Terry@BMS]

Helps higher HP cars in really cold weather, done using the IAT wire which is 1/2 of a fuel wire kit.

 

[brancky3]

Man that IAT line is flat. Do you have a comparable log in similar weather to see what the stock FMIC did to IATs?

Edit: lol didn't see you spoofed IAT. nevermind.
