Vanos Rebuild Start Hesitation

Only because of the Y axis scale, the actual values are the same.

Not the same: expected should be 12 degrees for some time but actually only get to 3 degrees

Not sure I understand what you mean. I was just saying that the exhaust actual and expected deviation is the same both cold and warm start.

Do you mean the exhaust cam expected should hold 12 degrees for longer than it does?

Is it possible to cross reference these values with a table from the MSS54 XDF?

I've tried checking the partial I pulled from my DME using TunerPro and the 1301 XDF, though a lot of the data is just jumbled so assumed there is something up with the 1301 XDF

On the graph you posted I see the cold start ex cam issue as I posted earlier: expected 15 degrees but actual is only 3, for a short duration but enough to be different than warm starting.

Both cold and warm start seem to be around the same, if you look at the Google Sheets spreadsheet of the values from that graph pretty sure line 8467 is where the engine is turned off with actual being set to 0 but expected being set to -10. Then line 9268 is warm start where actual is now -4.2 and expected is 9.5. Cold start has an actual of -1 and an expected of 12, you can see from my other cold start logs further up that I've also has -5 actual, 11 expected.

The numbers feel weird but can't tell if its normal or not. I figured there would have been a VANOS tables somewhere in the DME.
