Map 2 questions

[Mo-mo]

Hiya,

got the jb with all the trimming installed yesterday. I was at 3/4 tank of 91 and put in some octane booster. However my ignition timing gets as high a 43, afr is high 14s low 15s. Is there a link for these kinds of questions? I did a skim over the forums and did not find anything.

Thank you

Ign1 (absolute timing advance) or Ign2-5 (relative timing retard vs. cyl 1)? And is this at WOT or when you let off and are cruising? Both timing advance and AFR can get pretty high off-throttle in a modern GDI engine...I think I've seen 17+ AFR. But when you're doing a WOT pull you should expect more like 12:1.

Here's a quick writeup I did a while back on reading logs. It also has the link to BMS' explanation of each parameter.

Wondering if anyone could let me know if I am running at a safe level I have no idea. What my air fuel ratio should be. Please help someone.

I’ve had my JB4 for a while now just installing it what a difference it makes I’m only a little concerned that I am not really able to read the logs do you know if I am running in a safe range love how fast it is but I really don’t want to hurt my car

You really need to post a log (csv) for anyone to guess what's going on.
