Experienced Haltech but New to UpRev

last summer when I only had my modded exhaust and stock intake system.
I was tuned to 75
but few month ago I decided to do a test and my timing was the same with 70-71
so I lowered it
thats give me about 29-30 BTDC from 7000-7500 RPM
again , that depend on what the AFR is reading,
a drop or higher than .2 AFR will give a different timing value during a run.
its like to be in a sweet spot , if you get out , the bonus in timing is ruined by the wrong AFR

I did do some tracing on the timing map but I never think about what you seem to have found out in your previous post.
in the future I will look at it.
because I always tuned by the way the knock sensor feel, if its pull timing , I do some modification in the map to make the knock sensor happy.


I thought about that but I didn't want to screw up something.


I just did an average from B1 to B2 and modified the whole B2
cylinder 1 is higher but I should set it to the 3 or 5 because they are the one receiving more air than the front one.

before any change , B2 was richer
after the change B1 was just a tiny bit leaner , this is why I only gave 1 cylinder to be richer
I'm trying to have both bank having the same fuel/air doing a data log with the MAF V. and WB


to answer your last question ,
yes I do get in the 22 ,, my max was 22.7
I would guess to be touching the 23 once I install back my modded Throttle Body.
