Need help doing vanos test with INPA

[Bry5on]

So I had a question about the Vanos test.

One of my cars is starting to have the marbles in a can sound at low RPM with a load on the engine. Sounds like pinging but it's a fresh rebuild. It's the same sign you're hearing cars when you run low octane fuel when you get the marbles in the canned sound.

Doing some searching I came across several instances where they mentioned timing being off.

I have never heard the pinging before until recently, so my guess is maybe it would probably go away if I reset Vanos adaptations and then probably come back

So if I want to run the Vanos test, should I run it now and it's current state or should I run it after I reset adaptations?

And would a successful vanos test mean that the engine is properly timed

I also had these Shadow codes. I never saw a check engine light but I decided to check codes today and saw these Shadow codes. Inlet Vanos retard valve errors

This sounds like the CSL tune on stock cams if your marbles are below 2800rpm or so at medium/high throttle. Cam offsets will not solve this. I believe the only way to eliminate it is to remap several of the fields in the CSL file itself beyond a simple tune. As Heinz mentioned, I have created maps that solve this and bring back stock drivability. I call them the mullet tune. If you’re interested, shoot me a PM.

Thanks sir for looking. I really need to learn how to decipher these values my self

It's very simple, not rocket science.

The first job performed is STEUERN_EVANOS1_FRUEHANSCHLAG -> Command inlet VANOS advance until endstop.
When it completes you get back the SOLLWERT, German for setpoint, and the ISTWERT, which is the actual value.
The setpoint gets always set to -10, the value it expects to see is 0.
I would say +-1 would be deemed good, +-2 would be acceptable, anything beyond that and your engine just isn't in time properly.

After that it goes to STEUERN_EVANOS1_SPAETANSCHLAG -> Command inlet VANOS retard until endstop.
The setpoint here is 75, while it expects to see 60. Again here +-1 would be good +-2 would be acceptable, etc.

Next up is STEUERN_EVANOS1_VERSTELLZEIT -> Command inlet VANOS adjustment time
It returns EVAN_VERSTELLZEIT_FRUEH which is the time it took to fully retard the intake cam, and EVAN_VERSTELLZEIT_SPAET which represents the time it took to fully advance the intake cam.
We consider under 250ms-ish good here, DIS allows up to 500ms before it fails you.

The rest of the test is the same thing but for the AVANOS which is just the exhaust side.
The only difference being the intake ranges from 0-60, while the exhaust ranges from 0-48, same tolerances apply, exhaust is usally a bit faster on the adjustment due to less range.

pinging sounds more like cumbustion is not OK. Would check fuel trims and knock adaption too.

+1

Grab yourself a Bryson mullet tune

[nextelbuddy]

Maybe some bad fuel?

Possibly, I and to some octane booster and see if there's any change

[nextelbuddy]

Looks good, intake is 1 degree off but I wouldn't change it. So far nothing strange I could observe with these values.

I want to go can a few pages and compare the test results from my s54 turbo car and thus S54 wagon and see how they compare.

This is what my adaptations currently are using ecuworx




This is my first and 2nd vanos test run back to back oil temp was normal and i just came back from daycare drop off driving for 45 min with some spirited driving in between after dropping kids off of course.

[Tomba]

pinging sounds more like cumbustion is not OK. Would check fuel trims and knock adaption too.

[nextelbuddy]

Doesn't matter




Yes

Was the engine rebuild with different than OEM components?

The engine was built with all BMW parts from FCP Euro. The reason I question anything is because I used a non-bmw timing, bridge and pins when I did the timing.

The engine has been running great with no other issues other than this weird pinging sound that just started coming out of nowhere

I'm on the CSL tune with the non CSL Vanos offsets that I found on these forums.

If the Vanos test comes back clean then I'm going to try using a stock CSL too without modified Vanos offsets and see if that changes anything.

[Tomba]

So if I want to run the Vanos test, should I run it now and it's current state or should I run it after I reset adaptations?

Doesn't matter

And would a successful vanos test mean that the engine is properly timed

[BMWfanz]

Guys, anyone have 288/280 12.5 lift cams and who has done vanos test?

[Tomba]

Very cool!

Any chance you could whip up something for VANOS adaptions reset in INPA? It's a bit a chore to have to fire up DIS for every Vanos rebuild.

I'm busy integrating VANOS test in INPA and some more functionalities. Sure to add that one as well.

[Slideways]

Doesn't resetting all engine adaptations on INPA include the VANOS?
