Here you go! I will update the main post with "FP upgrade" stuff once I am more confident about best settings/etc. I will say that I am finding FOL (FP adjustment) really shouldn't exceed 90ish for most cars. dme will start to be weird with boost targets since it thinks fuel pressure is lower...

100% It will always be worth more than the Z4 counterpart later on because of this. MT or AT. The appearance and name provoke 99% of the engagement I get with the car.

map6_15 map6_20 map6_25 map6_30 map6_35 map6_40 map6_45 map6_50 map6_55 map6_60 map6_65 map6_70 1 1.5 2 3 3.5 4 4 5 6 5.5 4 3 Looks good, just gonna take a little boost off the top to help timing.

looks pretty good, add some boost up top now that you have octane map6_15 map6_20 map6_25 map6_30 map6_35 map6_40 map6_45 map6_50 map6_55 map6_60 map6_65 map6_70 1 1.5 2 3 3.5 4 4 5 6 6 5 4

Looks alright. You can update to V24 firmware or newer to clean up that throttle a bit, and may need to move FF up a little. No point in map 6 with that fuel, it is already having some corrections on Map 1 (that are OK)

I am pretty sure the JB4 disables when OBD is unplugged, so not really sure how log MG flasher. I guess theoretically you could try with a JB+ or other piggyback.

Hm, so you checked Load limit adjustment rates on each ROM?

I promise something is configured differently. Even Manual S58s have the same issue.

This is just supplementing my hypothesis. The issue is rare above 5500.

Yall... I think I finally found the cause of MT issues.... Yes, I have talked about the solutions, but I spent a while researching today and one theory lines up with every MT log I've ever seen. Behold: Injection Monitoring - A new feature for B58s, not in prior N55s/S55s. Injection monitoring...

Just take logs across the year and send em for review. Usually the car adapts on its own if you are using additive maps. 3rd gear, and do one Map 0 and Map 1.

It's possible that the JB4 just reverted to Map 0 if any safety was tripped. Whether it be fueling, boost, knock related. I can see if it was in a log. Next time you're on an empty highway ramp, just punch it in 3rd for a log. No need to wait for a track day and can still avoid speeding too much.

brother I have not even made a week's worth of my day-job pay doing this for a year ? I have no skin in the game so there's really no need to go on the offensive. I'm literally doing it for fun just like you have your tune thread. Because its the right platform for me and many others at this...

Yep, well, they've done it with N54s for almost 20 years without issue. I'm not concerned. Whatever table I shared not being the main one isn't really the point. Its just that variable base timing is not compatible with absolute boost targeting. Spoofing freezes all IAT-based timing tables...

Yep, just with the purpose of setting base timing. dme boost targets and timing jumping all over the place with IATs just doesn't work that well on JB4 absolute imo.. Like, you will lose power throughout the pull as dme targets climb and JB4 absolute targets don't. (and timing just drops) I...

If the car is great at 80 degrees out, try IAT spoofing at 100. 6cyltiming=100 (apparently the new app just has it listed as IAT spoofing)

Yeah absolute maps don't adapt super well with temps, so I have been recommending IAT spoofing when using them lately.

Yeah seeing typical MT stuttering. Let me know if you want to test this MT mode firmware and see if it helps at all. I am doing MT tuning/testing via PM since this thread would be a mess. Just message me there if you wanna give it a shot.

It probably was just MT stutter nonsense. I am starting to thinking MTs have a calc_tq limit of 47. You can see it in most logs. That's what this MT mode is supposed to do is limit the dme observed torque. Nope. This upgrade is not a flex-tune. You still have to target a specific E blend for...

For anyone on the fence about the FP upgrade, here's a 91/E40 car running trims at 25-35. It has similar boost and timing to a MHD/BM3 OTS E40 map, so I would expect similar power though it runs leaner on JB4. https://datazap.me/u/coloneladama/log-1734845093?log=0&data=1-2-3-4-11-14-15 So...
