I left the default which is 0 I believe....

No. Didn't he say the the default for 26.6 is FUD = 20 here:

Seems to be a little at odds with the first page post, but I think moral of the story in either case is that the default throttle logic for 26.6 is the iso25 logic.

1) Changed settings such that "ISO25" style throttle behavior, that enabled by setting FutureUseD to 20 in ISO 26.5, is now the default. And to enable "ISO26" style throttle behavior, which may reduce rattle and smooth out low throttle tuning at the expense of throttle response, you set FutureUseD to 20. Confusing, I know. Another way to put it is with ISO26.6 if you still have low throttle rattle even after raising up menu 12 then setting FutureUseD = 20 is something else to try.

I managed to eliminate my wastegate rattle by pushing up Base Duty (Menu 12) up to max however accompanying this higher duty cycle with the backend flash makes an extremely aggressive throttle pedal paired with the DCT.

Guys I have been overseas for 3 years and need a bit of help. How do I get the IATs to display on the dash? I tried search and could only find references but no explanations.

See the dash commands sheet in the first post.

2 - 3 for IAT on fuel.

Since upgrading to g5 iso, and backend flash I've had a problem with sudden throttle increases. If I just floor it in 2nd or 3rd, sometimes it will stutter first then after a second goes as normal. It will even do it sometimes when I shift 2nd to 3rd quickly.

Anyone know what might be causing this?

Has to be a torque limiting issue. I've had the same.

Nick, sorry for a very late response. The shift from 4th to 5th is very jerky. All other shifts with acceleration are smooth, very smooth actually. From 4th to 5th shift it does not want to shift quickly, it gets stuck around 45-48 mph area and then when it shifts it jerks. I don't know why it happens, its just in that 1 shift.

Yes I am on stock trans flash. I only know of Alpina flash, but I have not had that flash done. I was wondering are there any other ones?

wait so unless i insert a value of 20 in FUD then I dont have ISO 25 throttle logic??? when I upgraded to ISO26.6 in the notes for all the Future use there was nothing about what a value of 20 would do.

:
Low throttle upshifts lurk forward sometimes. I don't belive it's
Jb4 running related tho. I had it on stock and now alpina tcu flash even tho it got a lot better with alpina flash The cure is to stay more on the gas during upshifts. At least that's how I deal with mine regardless the map or software.It not a big deal and most likely trans hardware related.
Stock trans flash was 30-50% slower shifting overall. So Alpina TCU will help providing you don't always drive in D mode cause if you do you will hate it. It's only for S and MT perf oriented driving crowd

my tranny is stock and my mods are g5iso and dci and once and a wile I get a hard 1-2 shift that feels like a hit at a very certain thottle.

I asked this before amd dident get an answer if the jb4 does anything to the tranny programing.

im going to load up the 27.1 and see how the car feels im on the 25hex now

If there's not a write-up for any new firmware it means Terry is beta testing it and looking for feedback from anyone who is currently running it (after releasing it privately or in a post. see 27.1). Once he feels it's a solid firmware without any bugs he will post the firmware file on the first page of this post with the accompanying notes.

27.1 is new. There is discussion about it in another thread. I suspect 8/10 people will prefer it to 26.6. I know I do. But as always, I encourage everyone to run whatever works best for their needs. Some guys still prefer ISO19, some refuse to run ISO at all, and maybe once per month I hear from a customer who prefers their JB3 to a JB4. Live and let live.
