No there are not sufficient flash tools for the N55 platform yet to allow this sort of more advanced stuff.

You can write anything you want as a jb4 backend, before it writes however the app patches the binary to max out at wgdc of 40%, which isn't an issue because you have a jb4 doing boost.

Terry, your xdfs appear to be defined in Celcius whereas the MHD xdfs and Fahrenheit .
I've attached the relevant table values and breakpoints based on the MHD xdfs.

Can you confirm?

Seems OK other than the RPM break points which I'll be using later to rebuild the normal IAT timing decay. Next time I'll post them using the hub XDFs.

Donnie and I are working on a few things for i8a0s which has some extra codes we need to disable, table changes, etc, for it to work fully problem free. But he was able to get a taste of it last night. I'll let him post his log.

So needless to say, this is an AWESOME feature!

Built up lots of boost really quick while just lightly holding the brake. I used to have to hold the brake pedal all the way to the floor and would only build a fraction of the boost in the same amount of time. Car spun really bad in 3rd even with 555Rs so I short shifted in this log, but it should get the idea across.

Have a few minor things to work out, but this is going to help A LOT. Especially you single turbo users.

My GoPro was dead last night while I was testing, but it's charged up today so I'll get a video later.

Yep. I was only on the brake pedal about 30-50%.

Nice to see some results. My buddy just finished making me this anti-lag device and I'll be installing it later tonight to test

Went out and did some more testing to show some friends this anti-lag setup. Video for those interested.



Logs attached. Forgot to start the second one before going WOT though.

Good question. When I have tried brake boosting in the past the DCT did not like it and and I ended up throwing some throttle valve codes. Would be cool if this works though.

That video of this in action makes me drool! lol.

We found a little bug we need to work around. Note here at the end of the run IAT is at 140 degrees. When you tap the brake the circuit kicks on and drops temp to 90, and it triggers a 2F09 fault. It's another plausibility fault like 2F0C. But unlike 2F0C this one triggers a 3100 fault we can't seem to disable.

When the JB4 is running the system more intelligently it should be easy to work around. Until then Donnie and I are going to test some circuit modifications to work around it physically. I'll also start working on revised 23k22 firmware that deletes CPS and replaces it with two programmable PWM outputs that we can use to trigger this setup.
