VANOS Adaptation Values

[Cubieman]

Checking and adjusting the offset in the ecu will take 5 minutes. You said the vanos was fine prior the CSL ECU so your physical timing will not have changed just by switching the ECU.

I know the timing wouldn't have changed, its just Kassel is so adamant they have US spec. offsets in their tunes I am starting to second guess myself.
I did make a point of pulling codes before the swap, it wasn't the day of the swap but about 5 days beforehand.
I was pulling codes weekly up until the swap because I had an EGT sensor error so I was monitoring that. I am not %100 certain it happened after the DME swap but I am very confident that is indeed the case.

I see. So that means that it is important to get your timing as precise as possible, regardless of the DME's ability to set adaptations. Interesting.

I read it the other way. You could actually be a bit sloppy in your physical timing, and the ECU can adjust +/- 8.

I sure hope I don't have to reset timing. Planning on doing valve adj. and Vanos lockdown so I'll be in there anyway but not ready to do that just yet as I am not confident enough in my understanding of the procedures.
I am also not confident in my local indy shop's ability to perform such procedures. They won't rebuild vanos anyway, thats fine, just means I get to learn more and spend less...so long as I don't bend valves/ruin my pistons! Sure hope this all SW related, then I can stop dicking around til' 1am every night reading/worring.

The Vanos adaptation values are simply to allow for mechanical error when timing the cams and to 'sync' the camshaft timing values with the ECU zero points. They won't actually correct for any mechanical error.

I see. So that means that it is important to get your timing as precise as possible, regardless of the DME's ability to set adaptations. Interesting.

Yup!

TunerPro > File > Open Bin > Select your tune.
TunerPro > XDF > Select XDF > Select the CSL XDF you downloaded.
TunerPro > Ctrl + F and search for K_EVAN1_OFFSET, double click the result to open the parameter, then repeat for K_AVAN1_OFFSET. Edit each value as per my screenshot, press save on each and then save out your bin with 'Save Bin as...'.

So I just copy/paste that into notepad and then it's used in tuner pro? I am getting off topic here, sorry.
You will likely see a new thread regarding this in the coding section if I can't figure it out.

Thanks, I'm not quite sure how to grab the CSL/ 401 XDF and load it into tuner pro. I'll get tuner pro later today and start reading up on how to do what you have described.
Thank you Martyn!

You have error code 94, which is a fault relating to inlet vanos adaptation. Because the cam isnt adapting your value is 0.

Grab the CSL / 401 XDF, load it into tuner pro along with your tune and search for K_EVAN1_OFFSET and K_AVAN1_OFFSET in the parameter finder window.

Set them to match the below:

[Cubieman]

Correct the offset and you'll be fine. The value of 0 does indeed mean it's not adapting.

Could you briefly explain how the error code with the vanos inlet presents itself when the vanos inlet isn't adapting at all?
One member PM'd and suggested that if it is a timing issue with my error and my current adaptation values he thinks my intake camshaft may not be moving at all via vanos, therefore the 0.00 value.
I sent a partial to someone that is going to check the offsets, I am very grateful for that.

[Martyn]

I may have to do the same with my US cams, but further testing needs to be done before I point my finger 100% at the tuning.

After resetting adaptations my inlet vanos error (94) came back once again.
One thing that confuses me is the fact that I have an inlet vanos adaptation value of 0 yet the error is occurring. From what I understood a value of 0 meant that the Vanos isn't compensating at all for things such as faulty timing etc.
I thought the margin was 8°? Does the number displayed on this psuedo-screen shot of mine indicate that the inlet vanos is adapting 0°?
I don't fully understand what is going on here, a vanos test would be great. But until I figure a way to load DIS it's running this way.
Also, I am risking damage running the car this way?

Correct the offset and you'll be fine. The value of 0 does indeed mean it's not adapting.

Hey Paul. Good to see you’re on the new forum.
I’ll chime in to recommend Paul for anyone having issues with their CSL tunes, cams, offsets, whatever. I couldn’t get the CSL tune I bought running right with my 288/280’s relating to the offset issues being discussed here; the tuner said it was incorrect timing, and basically said there was nothing more that he could do. I got in contact with Paul after reading some of his posts about this issue on the old forum. He pretty much had me running properly right away with adjustments he made to my tune. Turns out I didn’t need to re-time it 10 times over. I ended up cutting my losses with my original tune and went with a tune from Paul.

Glad to be here, and thanks for the comment Derek 👍
