7) v31.4: Revised spool up logic to be more aggressive. It's possible this new logic may result in boost over shoot in some situations so keep an eye on it.
8) v31.4: Added FUD=95 setting for larger than OEM turbo duty bias tuning.

I can attest to 31.4 being worth installing.

What does FUD=95 do on a technical level?

E series n54 only for the moment. But can add to other cars as needed just email if you have a specific issue tuning in larger turbos on the n55.

Terry, out of curiousity, what chnages were made for the decrease in spool time? Will DWP, etc. alter the effectiveness of this?

Basically I made the spool up mode PWM logic more aggressive. Now it holds PWM to 100% until boost is within 3psi of target. Previously it had a dynamic formula for this. The new logic is simpler and better. But needs to be evaluated across a wide range of cars and conditions to ensure it's working as it should be. The old dynamic code was getting long in the tooth as they say.

Very cool stuff!

So far so good on the new firmware. Car runs like a top.

Only thing I'd like to note, my WG rattle seems to have gotten a bit worse since the last firmware I had Ver. 31. Still much better than pre-31, but it did get louder.

Does anyone still have a standard exhaust and use JB4 CanFlap function.

When its set to ON (always open) - Menu 4/5 the flap still closes.

If i build up the trottle slowly it will hit 3K and shut all gears i believe.

I dont know if this was caused by a new update or i just havent noticed before anyone else notice this? Should it always be open regardless?

Same experience here, boost transitions feel quicker/smoother with 31.4, but audible rattle is back now when I build boost at light throttle, maps 10 and 12 are set at default.

May have missed it, any suggestions for settings to get less rattle on 31.4?

There are no changes to the rattle logic within 31.4 so I don't know what the difference might be.

No problem, at the end of the day it's not really something to be simply masked with software as you've stated before.

I'll tinker around with different values in the rattle fix menus and see what I come up with.

Default Hazard Lights on Dash Stay On - 09-06-2015, 05:53 PM

I have a new issue that just popped up a month ago where the hazard indicators on the dash stay on when I start the car. I have to stop the engine, pull the key out, then restart to get them to go off. Outside hazards work normally throughout this time, so it is just the dash hazards that do this. Also, if I turn the JB4 completely off by going to 0/0, it does not do this.
I tried reflashing with the same firmware I had been using (G4_082112.HEX) to no avail. I have no codes.
I'm not sure what version JB4 I have, but I bought it in March of 2012.
Is there anything I can do to fix this? I've searched these forums, and others, and can't find anything like this.

Thx,
Pete

1) Upgrade to a new G5 board for $150 on our site.
2) Raise the menu3 in dash shift light to 6000rpm.
