SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

[ColonelAdama]

@ColonelAdama

Tried them out and recorded 4 pulls. The first has a pretty low IAT.
Just me looking at them noticed timing looks off on the second pull? Also is it normal for the throttle to break up that much? It also looks like my FF and WGDC are inverse to what I have seen on some others logs?

Let me know what you think!
This was with e30 on the dot

Logs look great. One pull with a single cylinder 3 degree correction is nothing, and honestly that's where you want to be. It means you are just at the right amount of boost for your octane. It was the highest IAT pull in your log too.

FF and WGDC look nearly perfect as well. I would just drop FF by 2 or 3 until throttle mostly clears up (ignore throttle cut during spool - only fixed with MT firmware, and doesn't matter that much)

and regarding the FF and WGDC curve, ideally WGDC is just slightly above FF at all times. that indicates boost is as close to target without too much throttle closure. They behave a little differently on additive compared to absolute.

Added some info for getting started tuning MT cars, and linked to the MT firmware in the original post.

Installed JB4 and Fuel It sensor. I’m on e25 and on Map 1. Only got about 15 mins to test drive.

Spent 15 mins on map 3 on fwy and street but I was told map 3 is sus so I’ll stay on map 1 until I get some logs in.

updated JB4 firmware thanks to @ColonelAdama

Not sure if I did this right. Had a friend do the data log for me while I drove.

MT: Went from 3rd get to 6500rpms, but unfortunately it was 95+ degrees out. I was on Map 1 with E25.

Mods: HKS Intake with CF air box, CG Catted Downpipe and HKS Exhaust.

The only thing I would be cognizant of is if you get the burger meth kit, You will also want a charge pipe with multiple bungs. I used the one from Burger as well. It integrates and tunes rather nicely!
I have been rather happy with the setup but if you take it a step further and go away from JB4 you will likely want the snow/aem kit. (long term plan for the car?)

The one downfall of the Burger kit is the housing for the meth won't fit under the hood like the AEM/Titan kit.

Edit: Car made 466whp. Assuming would have been a bit more if catless. Made over 100whp from stock to custom tuned/meth.

I have the same same kit only with a catless down pipe.

Try Map 1 again but you need to have the pedal to the floor during the pull. 3rd gear from 2500 to 6500

Most likely the car will need a good bit of wgdc changes buy want to see how it looks first.

Hey Adam,
Here's a log on map 4 (this is a 2021 m440i but should be the same thing). https://datazap.me/u/sa90h/m440i-ma...25-26-27-28-29-35&trim=23&tmin=2.80&tmax=4.00
There is a map 1 and map 0 pull in here, but that was with poor fuel, and the map 4 log was E30. I know the map 1 pull sucked because of fuel, so just ignore that one. Does it look good? Car has a catless downpipe btw. Thanks.

Got 3 runs in. Next on my list is a phone mount.

Also,
Here's a map 6 0-60 pull using the previous owner's custom map by Jesse. Previous owner had the exact same setup so we thought we'd give it a go. https://datazap.me/u/sa90h/map-6-0-60-225psi?log=0&data=1-4-11-25-26-27-28-29-36

Here's another run when we increased boost a bit. https://datazap.me/u/sa90h/map-6-23-psi?log=0&data=1-4-11-25-26-27-28-29

Use this one, it is actually working quite well for your car already. Trims sitting around 45, timing perfect.

Try these duty bias settings out to start:

duty_15	duty_20	duty_25	duty_30	duty_35	duty_40	duty_45	duty_50	duty_55	duty_60	duty_65	duty_70
41	41	41	41	41	41	44	47	50	50	50	50

Sweet. Thanks for the advice as always!

Was only able to get 2 runs in. But it felt smooth.

Still on E25.

Less boost that stock and throttle is closing 50%.
