AFR Safety settings

[core-rider]

Trying to setup my AFR Safety settings and this is what I have so far... wanted to get the collective brain trust to look and see if this is a good starting point, or if something looks off.

Also used VE Analyze for the first time to look over my 8.02 pass log that was lean and I like the numbers I'm seeing it added so testing on that and we shall see what happens. Just wanted the safeties in place this time to make sure everything stays where it should!

I do 1.0 above 100 load% - I’m commanding 11.5 there, and depending on conditions it isn’t unusual for it to hop to 12 and back to 11.5. For my tune and setup 0.5 would be too tight. But that’s just my tune.

AFR safety has saved me when I had fuel pump issues.

I figure it's better to start too safe vs the consequences, but this is what I ended up with mine. Now I was shooting for a lot more boost so keep that in mind Also be ready if it kicks in, it can feel like a light switch when full on safety hits, there's also an AFR warn that you'll see in the logs as you approach it. Be sure to turn on logging for "AFR warn" and AFR "shutdown" if you're logging to the SD card or setting up MLVHD.

unrelated to pimpxs but last night i melted a piston in my car because i didn't have the AFR safety configured well enough and had a fuel pump relay on a dual fuel pump system fail. So definitely do this.

Bummer, sorry to hear that Travis. I should dig up some of my old carnage pictures to commiserate over.

I've got carnage pictures from a brand new motor that wasn't even started some where too...

I've seen those, it was like a Discovery episode where they pull up treasures from the deep (we can laugh now, right?)

Hahaha...yeah we can now. Although I can still hear the engine builder when he said "was this motor under water?". And my reply was " WTF are you talking about ! "

Not a great feeling hurting your new motors!

How did you get to the AFR warn/shutdown fields? I looked in TS and MLV couldn't find the dialog.

Datalogging ---> SD Card Datalogging

Datalogging ---> SD Card Datalogging

That was me overlooking the obvious, my logging profile has:

status: AFR Warn
status: AFR Shutdown

Your version groups stuff logically while mine puts things in random subcategories to make it interesting.
