PROcede Ignition Timing control- Fact from Fiction
Ok... so I got a bit tired of this debate regarding CAS offsetting and it's effect (or, as some have claimed, it's lack of effect) on actual timing advance/knock resistance. I thought the concept was pretty straight-forward and un-debateable. But I feel some parties suggested that it was more of a questionable "theory" than the testable and repeatable fact that it really is.
So I took the time to conduct a bunch of timing experiments today. All the while logging Actual and DME (perceived) timing advance in a number of map configurations (ranging from zero PROcede timing conrrection/CAS offset to several degrees of timing correction/CAS offset). And the results speak for themselves. My questions to the forum is: Can I present this info (datalogs), all of which is easily repeatable by others running CANbus PROcedes, without the thread turning into a flame war? It's going to be a good thread just as long as we can stay on topic. Lots of useful tech info. What do you guys say? Cheers, shiv |

In my experience running the standback and the juicebox, once the juicebox tune knocked and adapted to the power level the timing on both tunes was identical, and i was pulling timing with the standback. So without starting a flamewar, based on my experience cas offset works for about 15 seconds if that and then the car runs whatever it wants to run.

Yes, please present and make sure it's not just the data, but clear conclusions drawn by the data so that the layman can make the connection between the two and the brainiacs can see if the agree with the conclusions.

No problem with the data except can you post a 2nd set of logs, with the car fully adapted w/ and w/o CAS offsetting? TIA

When you change boost, no kidding timing is going to be different canbus doesnt having anything to do with timing control. The ecu will run max timing on its own. I was a big non believer of no timing control, but on this car, its usless from the countless testing ive done with various systems/octanes/meth. Hell on meth i added as much as 7 degrees of timing over a matter of 8-9 dyno runs, run one and run 9....guess what, same actual timing. |

Well, I for one would love to see what Shiv has to show us in this regard...so please do.
Anxiously awaiting the update next week and the custom tune documentation...please tell me the in dash boost and ait readings, etc. are coming in this update?!?! For now I guess I am going to be switching some coil packs, as I threw a 29d1 code (misfirings cylider5) today...6426 rpm's, I think a coil went bye bye, but we shall see, I think it is time for Tischer to the rescue! LOL Thanks Shiv, now please post the timing data.

There is always more than one road to get from A to B and I am curious to see how Shiv lead us to B.

i don't see the need to pose the question shiv, regardless of what u say this is a public forum and its going to have people with differing opinions regardless of fact or opinion.

Interesting. I never knew procede did knock control on itself. The only way I would imagine you prove it is using a high octane map and running low octane. Then run a Bavarian tech for CAN interference or even knock on certain cylinders. If there is no knock present it means the procede did its job. Same thing can be done with the timing.

Please present the data as a service to the community. Hopefully, people will choose to be objective to better understand how this all works. There will inevitably be partisans who will attempt to debunk what you present. I recommend the moderators keep a close tab on things with a heavy hand...

I have about 3 MB of logs which show the opposite. I welcome and would like to see opposing data. But none has been presented as of yet.
