Do you have any other brands you can try? Fuel quality can be very regional, so nothing against Shell generally, but you might have better results with another brand. You could also try mixing a...

These to me look more normal, but fighting poor fuel. From the logs it looks like the car is trying to adjust timing but then pulling back because of knock. What fuel are you using - brand/octane.

Assuming pulls were at full throttle log looks fine (Pedal position is showing like 75, but throttle is showing 100).
That is a very conservative map for a non RS model. I would just use the...

I'm sure you noticed that both these logs look normal! Try Map 3 to see if the zero Ign1 anomaly comes back. Hopefully it was just a fluke.

Pull looks good. On a non-RS, I would just use the stock maps BMS provides. They are dialed in well for the car. Looks like you are at a Map3 level with what you just ran so maybe start there. ...

Weird that your pedal position is between 80 and 90 instead of just at 100%. Throttle is 100% so I assume you had it floored. Timing looks fine except for one tic where it went to zero at time...

Yes start from scratch if you can. What year and model car do you have? Are you doing fuel wires and EWG wires or just basic JB4 unit?

Not very good logs to review - way too long and just normal driving. Ideally log 3rd gear in manual mode from low RPM all the way to redline before shifting.

I open the csv file in excel so the entire log is easy to review. You switched to Map 5 at time stamp 198.25.

Timing looks good on all the pulls. On the map 5 pulls your trims are maxed for much of the pull and AFR is slightly on the lean side. Maybe back down to map 4 and see if trims/AFR looks better.

Little concerning that your fuel trims max out at about 3500 RPM and stay there for a bit and your AFR is a bit lean through 4500RPM. Timing and other factors look OK.

Regarding use of Map 6 -...

As much as I like seeing zero to sixty logs, its not ideal for evaluating the boost level you are running. Use manual mode in 3rd gear from low RPM - say 2500 all the way to redline...ideally you...

Yep, no doubt the E content is upping your trims. Just want to make sure that you don't run out of fuel delivery capacity and run too lean on AFR. AFR still looked OK on the logs, but if you go...

Looks decent, but probably the boost limit on that fuel as your timing drops a bit below 5 through the mid RPM range. Guessing you are running 91 octane?

Have you done any hard zero to sixty runs while logging? It will only register it if you are running a full zero to sixty under full throttle (or close to full throttle).
