You know the reason. I'm done provoking him for the moment.
There was no hostility meant in my last post. Sorry if it came across that way.
I was just pointing out that I know a thing or two about CAN, I had to learn myself, and it cost me money, and I didn't need to argue or justify my posts where I did mention the technology and was challanged.
Cheers,
Hymee.

If not, I can just go look it up myself and share it here. Its not like that information won't get presented on the forum one way or another.
I was just giving you an opportunity to share your conceptual knowledge.

I'll take a look tonight and see if I can find the source of that info, but I sure as HELL didn't sign anything or pay anyone for it. I spend my money on fuel and the occasional mod.
CAN is a 'multimaster system' with line topology and real-time capability.
Unique 'identifiers' contain information not directly related to the address of a participant, but to the contents of a message (such as temperature, rotational speed or linear speed).
All participants check out the identifier being transmitted and decide if the type of message is relevant to themselves.
In this way, all messages can be received from many or all of the participants simultaneously.
The unique identifier also determines the priority of the message relating to bus access.
Should a number of participants try to access the bus simultaneously, the higher priority message is guaranteed to gain bus access.
Standard format (11bit identifier) and extended format (29bit identifier) are two different message formats that can exist on the same physical CANbus.

Technical enough for a conceptual understanding, not technical enough to recreate or interface with a can bus.

Keep in mind I'm not a tuner and I really don't have any evidence. It's just a thought.
I have the stock box with the Racing Beat ram. I was running lean at the top in every gear. Even 1st which negates the ram air giving any bump to the AFR's.
Running a new flash now. I'll post when my car's had time to get acclimated to the new flash.

"CAN features an automatic 'arbitration free' transmission. A CAN message that is transmitted with highest priority will 'win' the arbitration, and the node transmitting the lower priority message will sense this and back off and wait."

Yep. My LTFT was running at 1 and my STFT was at 0 to -1 when I did the flashed 2nd gear pull. I had been running that flash for 3-4 days with many trips.
My stock run was the day before I received the AP and I don't know what my trims were. It was the stock tune. I hadn't reset the car, ie removed/disconnect the battery, for over 6 months.
Yes, I'm running the 1b.3a right now. I've had it on for about 10 miles. Just from looking at the RT display and only going about 40-50% throttle to about 5k RPM's my AFR's look pretty much the same. They might be a bit lower, but without logging it's almost impossible to tell.

Ideally, you want it to always be just under 12.5 on the Level I calibration.
Most drop after 5500.
The lean cars behave totally differently.
BTW - lets move this discussion over the the AccessPORT thread. This is the worng place for this.

Looking at them and knowingly publishing their contents publicly are two different things.
Whether or not that graph is part of one of my calibrations, you believe it is, so you are admitting to knowingly violating copyright law.
