Log read

Can someone read my log please. New to this and don’t understand at all. I have the burger tuning 450 kit installed on 2019 gt1, 93 octane. Had ChatGPT read it and it said something about high WGDC

I keep seeing these double-spaced logs, and wonder if that's a setting or the new normal for the JB4 app. Definitely makes longer logs harder to read (especially on mobile). Yours is nice and brief though -- looks like WOT from 43-80mph in 2nd & 3rd gear, Map 2.

Do you have "fuel wires" (O2 sensors) or WGDC connectors? Your AFRs are in the 12s down low & 11s up high which is fine, but the O2 intercepts let the JB4 lean you out a bit in higher revs for a little more power. WGDC connectors let it manipulate the wastegate duty cycle, but ChatGPT probably thinks those are absolute values (50 = 50% duty cycle), when in reality it's the scaling the JB4 is trying to do (50 = no adjustment I believe).

You have good base timing advance through the rev range (ign1) and no real cylinder-level corrections (0.8s in ign2-6; less than 3 is fine). IATs rock solid at 71 degrees and you hit a peak boost of 17psi, so I'd say that's a very healthy log.

Thanks man and I cannot remember. Is it this? Also I would like to go up to map3. Is it really as simple as mixing 93 with 3-4 gallons of e85 or is there more to it. Not a “car guy” at all but want to make sure it’s right. Thanks

Is it this?

Yes the big hex bolt in the metal cup is your O2 sensor (in the exhaust), and the red things are posi-taps intercepting their signals. BMS calls them "fuel wires" because they're used to adjust air:fuel ratio.

The general guideline for the maps is that 1 is for 91 (California/Canada premium), 2 is for 93 octane (everyone else), and from 3 onward you'll want some kind of octane booster. The maps are conservative so your particular car might handle map 3 on just 93, or it might knock on a hot day.

Do you have E85 around? If so, try 4 gallons in a tank (and you can just add a gallon per quarter tank for partial fillups after, no need to run down to empty). Depending on how the logs look, it might be fine or you might need 5gal.

Yep I do. Thanks for the help.

So if IAT get higher, is one of the only ways to make them lower a CAI or intercooler?
