possible to implement in ME7?

Is it worth?
Can you search for more tech data of its logic?
Say
If ped >95% and b_kuppl =1 and nmot > 4000 and pvdksd > xxx mbar then
 <dk = 100%
 B_austget (forget how it's named,  cutoff condition)  = true
eof

Ya?

I think its actually maybe more something along the lines of, instead of opening the dvs and closing throttle, cutting fuel when off ped, don't open the dv, go WOT, cut off fuel.

Maybe even eliminate the DV entirely, and go WOT+fuelcut in all DV actions? Or is that insane?

Note that you will lose all engine braking off throttle which might make for a weird (and possibly unsafe) track experience.

Probaly need to close throttle (and maybe open dv) on brake application for safety reasons.

Brings diesel to mind.

Disagree with this

"Note that you will lose all engine braking off throttle which might make for a weird (and possibly unsafe) track experience."

If the engine stops making power, you'll slow down, not to mention the cylinders will still be working against compression,

When you don't have fuel or spark in cilinders. The engine breaking is about same with closed or full open throotle.
I know that beacuse on old engine drive by cable, somethimes I shut ignition off but leave throotle full open.
The only change i noticed is engine noise, maybe maybe little less engine braking with full open throtle, but I am not shure becuse is hard to notice diference.
 

Wonder how they're dealing with catalysts not melting down during that scenario...

Also, yeah, the whole engine braking thing is BS (imho), if anything the engine braking effect will be greater because the motor will be compressing air in the cylinders rather than drawing a vacuum. Same reason diesel motors shut off the air supply when turning off for a smooth shutdown.

I'd agree with Nyet's comment that this might be more to do with avoiding a recirc/dv opening, you get the additional mass flow through the exhaust that would otherwise be diverted or released, so compressor shafts don't slow down as fast, thus it can be branded as a mild form of "antilag" and that pleases the Porsche marketing department as they can put a spin on it and make it sound super fandangled.

Nyet, If you use the same scenario, but not to cut the ignition but the fuel or is it not possible?

Interesting... I *think* a simple routine to open the throttle during overrun would be most (if not all) of what's needed?

How could we retain vacuum assisted brakes in this situation? Repurposed N249 reservoir?

I doubt that the brakes will disappear, the system with an ejection pump allows you to get a vacuum with boost and check valves hold it. Or not?

I don't think I have a suction jet pump any more, servo assistance hangs off the inlet mani via a check valve ???

One way to find out I suppose, I've planned out the ASM patch - I just have to write and then test. Will report back later this week.

Interesting! Let us know what you find out.

BTW i agree about the engine braking comments; I dont see how you'd lose any considering engine compression doesn't come primarily from manifold vacuum.

You guys are mega optimistic about this stuff.

Go on try.

Monitoring will tell you to FUCK OFF if you try to do anything with throttle with closed pedal.
It will tell you to FUCK OFF on every single level.

As it should, because if you make any bug in this code, or something goes wrong you have the potential to kill yourself, as the car can floor itself when you lift or when you start it even.
Think REALLY hard about WTF you are doing.

>95% throttle is just noliftshift, that's fine - fuel cut, ignition cut, however you want to do it. We're not talking about that here.
0% throttle and antilag with a revlimiter is fine too to keep turbo spooled, it still has a rev limiter.

Flooring throttle, cutting fuel as the only source of torque reduction, you better have REALLY good code for that.
Like code that takes into account EVERY scenario, such as a failing clutch or brake light switch and so on. Worst case you're gonna drive yourself into a wall.
And you better NOT just turn off the entire monitoring.

Understood about dangers. I should probably have prefaced my post with your warnings, they are all valid.

;D yes prj, all duly noted.

You're right, writing into wdks did sweet fuck all - it was fun trying though!

I love PRJ. He should be our prime minister.
