Not sure what the throttle dip was about on that pull. When your throttle comes back about 3k RPM the rest of the pull looks healthy. You probably don't need to start your pull quite that low in...

Sorry, missed the "BP". Might try a different brand. You should not be getting knock on 93 Octane. EWG wires are independent of the other stuff. I would go ahead and install them and keep dialing...

Looks like the car is fighting knock in that log. I would suggest using stock maps and go to map 2, log, and move your way up the stock maps from there until you find the ideal target. What brand...

Yes, too rich is too much fuel. But too much fuel at +6PSI Map 4 could easily turn into not enough fuel for +9 psi. Also, don't want to speak for BMS on this, but I think they just meant its on the...

The JB4 has NO effect on daily fuel economy. You can see in a log that the total boost at light throttle is not effected at all by JB4. It is only when you go WOT that the extra boost kicks in (its...

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.

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.
