I don't see any obvious issues but go ahead and update to the latest v10 firmware so we can rule out the older firmware.

Map 1 - 91 Octane

According to the graph, boost was fluctuating a bit.

Also, what should we look for on Trims?

Thanks

Log looks fairly normal to me. There isn't any adjustment I can suggest for it.

Fuel trims should be level and and drop as fuel enrichment increases.

I have no idea as far as that's concerned. My knowledge of how turbos work and how the JB4 or any other sort of tune works is limited.

Did a few passes earlier this week. Car feels great. Launch control with the diff bracket on Map 2, even with all that torque still rips with very little wheel spin (RWD Stinger here).

I'm not sure what the ignition timing is supposed to be @ WOT but everything else seems ok I think?

I think it's a 'global setting'. As for the Map 6 details, they are exactly that, just for Map 6. I think they just lumped all the user adjustable stuff in one location in the app for convenience.

Thanks Terry.
Unless you are trying to diagnose some specific issue any non-WOT log isn't going to be useful for providing you tuning advice.

No we won't be able to. Poor idle is usually a vacuum leak. If a plug was bad you'd get misfire codes.

Yes that should be ok. Not likely to damage anything but when it comes to tuning more boost more risk all else being equal.

it's only for one or two 1/4 mile races ... I made a bet with a friend and he does not believe that a Genesis G70 can roll down 12 seconds and I miss him almost nothing with a time of 12.04 in map # 3 ... after having my little piece of paper I return to map # 2 which is very satisfactory!

I just got my JB4 with fuel wires installed on my AWD GT, only mods are a DIY CAI and Denso plugs at .022 gap. I'm limited to 91 octane fuel.

Same section of road and IAT was 96 deg and 75 deg ambient at the start of each pull to try to minimize variables.

I need to figure out how to view these logs in graphical form on my laptop but haven't researched it yet.

Attached are two logs, Map 0 and Map 1 0-100 mph with launch control. It didn't feel like as big of a gain as I was expecting after reading everyone's reviews so I'm hoping you can look over the logs and see if everything looks correct.

What I'm curious about is:
-Is it required to engine off/engine on after changing maps to get the change to "take"?
-Whether 10-12 psi is normal for stock/map 0?
-Whether it looks like I'm getting the right amount of added boost with map 1? Seems a little low to me (13-13.5 psi average?).
Whether it looks like I can try map 2? To me it doesn't look like it's detecting knock currently but I could be wrong.

Thanks for your time.

-No. You can change maps while driving.
-Yes. Factory tuning is limited to 12psi peak.
-Yes. I believe each map adds approximately 2 psi.
-Yes. 91 octane is fine for map 2 and could work for 3 possibly.

Thanks. Mine doesn't seem to take the map change until a power cycle. I put it in valet mode to verify and it stayed there until I turned it off and back on. Searched around and found no mention of needing to do this, hence the question.

Hoping Terry will look at my logs.

I would wait for terry to give the ok for your map 1 then try out map 2 on 91. I would never even try to run map 3 on 91 without a good octane booster or adding e85.

Is there a way to log time in seconds with the ECU's real-time clock so datalogs can be used to precisely extract 0-60 or 0-100 times?

Here are two 0-100 pulls on map 2 with 91 octane, let me know what you see. Thanks.
