About 1/3 the way down on the page here: Kia Hyundai JB4 - N54Tech.com - International Turbo Racing Discussion

Currently at "JB4_KIA_9.hex" This is the first sticky page on the Kia JB4 thread.

THANK YOU!
Elevation does play a role on turbo longevity so you'll want to stay more conservative on the mapping. But this map2 log although short looks OK to me.

Default JB4 Installed - 05-30-2019, 07:49 AM

Installed JB4 last weekend with fuel wires. Currently running Map1 but planning on sticking at Map2. Only 4K miles on the car so I am pretty skittish about doing too much too fast. I have a 2019 GT2. The only drivetrain mod I have besides the JB4 is the Agency Power intake.

I have attached my log from this morning. Please let me know if you see any concerns.

Thanks in advance,

Chad

I have been running map 2 since 4000 miles and now have 15k on the car and haven't had any issues.

How do these look Terry? Just installed the JB4 tonight! (didn't do the fuel wires yet though)

2L with a Spectre cone on the stock intake tube. Felt GREAT, but just want to make sure nothing looks funny.

Thanks!

Looks good to me! Update the firmware though so we get cyl 2-4 timing next log.

The first 5 differential braces we shipped had the holes in the wrong spot on one of the machined pieces, thanks to a screw up at the machine shop. Finally got the replacements back from powder coating and shipped today. So if you've been waiting for one you should be emailed a tracking number. If not let me now so I can ensure it went out!

Here are three more with the fuel wire installed. All map1... can't do map2 yet because I still need to gap the plugs.

The last two runs, I think I had the dreaded misfire.. the throttle gave out in the middle of gear 4 even though I still had the pedal to the floor...

I have the HKS plugs now, but just waiting to see my brother-in-law (a mechanic) to help gap and swap them in.

The good news though.. the last run.. 0-60 was 5.775! I read somewhere stock 0-60 on the 2L RWD is 6.6, and I've got AWD.

I think I will just ride around on map0 until I get the plugs swapped out, and remind myself of how sweet the JB4 really is once I can graduate to map2, and hopefully map3.

I had a similar issue to yours where I was loosing power in the higher range. It is mostly cured now but Terry recommended Map6 with +1psi across the board and log. If the Throttle doesn't dip when WOT, then go up to +2psi and log.
Ironically +1psi across the board gave me 5.6secs on my 2.0T AWD Prestige. Best stock I could get was 6.0secs.

Terry, maybe take a look whenever u get time? Did I miss something in the settings for WMI? I'm also running about e30 on map 8 for the first time, and it didn't seem as powerful as my map 2 runs on pump gas. My imagination? Traction issues?

Yes let's get the plugs done and revisit map2!

Boost and timing are higher on map8 so maybe your imagination. Dragy is good for comparing trap speeds to confirm power is as the log looks it should be.

What fuel pressure(FP H) values should we be seeing on 3.3T's?

I heard it is a 150 bar system. And I assume it is using MPa. I only see 10-11 on the FP H column? The numbers remain steady, but the math doesn't checkout....

Yes it's in MPa. Pressure goes as high as 2500psi but normally lower at full throttle. Runs around 10-11. When it gets below around 7-8 you'll start having issues.

Reading through all the posts, I think I'm still a bit confused on what I can adjust for the Future Use D "bit" settings 0-7 knowing I only run Map 1 or 2 with fuel wires. I have V9 Firmware installed.

I've read about pedal mapping and being linear, but is that no longer an option to change? If it can be changed, what setting provides better throttle response?

Is there a way to add more boost in gears 1st, 2nd, and 3rd (I'm AWD)?

With fuel wires installed and to get appropriate data logging, what "bit" should be on?


FutureUseD BIT settings as of v7 firmware:

bit0 - Turn on to disable JB4 fuel control, also required for accurate AFR logging if fuel wires are NOT installed
bit1 - Turn on to enable fuel control adjustment by RPM, default values of 80 across will match internal mapping. With default setting JB4 uses internal settings for fuel control.
bit2 - Turn on to disable JB4 hot/cold water & oil temperature protection
bit3 - Turn on enable IAT/timing spoofing, requires wire added to JB4 harness and 6cyl setting for spoofing level
bit4 - Unassigned
bit5 - Unassigned
bit6 - Turn on if vehicle has an aftermarket flash map loaded to the ECU
bit7 - Unassigned

v8
3) Added option for a more linear pedal input to boost profile mapping. The default pedal mapping is FutureUseD bit7 OFF, while setting FutureUseD bit7 ON enables the more linear input mapping.

v7
3) Adjusted JB4 interface such that fuel bias values no longer need to be entered for fuel control to be active. They can all be set to 0, or left at previous settings, because they will be ignored unless you enable "manual" AFR tuning under FutureUseD bit1. NOTE if not using fuel control wires no changes are needed but logging of AFR will not be accurate unless setting FutureUseD bit 0 on.

Fuel Control Wires:
These add on wires attach to the JB4 harness and your vehicles sensors to give the JB4 the ability to directly change the air/fuel ratio. The factory tuning runs in the 10:1 range and leaning that out to 11:1 has proven to be worth significant power at higher engine speed. Note these are preinstalled on the JB4 harness now so only need to be attached to the o2 sensor signal wire to enable.

No setting changes are needed to enable the fuel control wires.

The by gear settings are used to subtract boost by gear, generally for improved traction. They are not used to add boost by gear.

No setting changes are needed for fuel wires. The tuning presumes they are installed.

The linear mapping option would provide "worse" throttle response as there would be a lower boost target at every throttle position other than at full throttle. If you want more than the JB4 alone can offer checkout our pedal tuner.

Hi Terry

When confirming my fuel wires are working what should I look for in the logs so I don't have to hassle you every time the car gets a service after I reinstall the wires.

See attached log from this morning

Thanks

Do a run long enough to see fuel enrichment moving in the log, and then confirm fuel trims bank1 and bank2 are relatively close together and not over 40 after fuel enrichment has been above 80 for a second or two.
