Yeah....take your time....work down that tank of gas and give the 99 ron a try. I have heard that as well about ECUTEK. BMS (JB4) believes the ideal for our cars is low 12's. If you install the...

There is no way to add fuel with JB4. Mechanically you would have to add an upgraded fuel pump. My conversion showed that the rom 103 is 97. Do you have anything lower available? Here in the US...

Is that a special race gas? That is a very high octane rating. Likely the car is calling for more of that fuel to reach its AFR targets. Do you have any standard 93 octane gas available to you? ...

Yes, your trims are maxed more than I would expect. Nothing alarming but it will limit you in adding more boost. Learn to read your logs and keep logging. This may just be an anomaly. Try...

The map 6 didn't look great, but better than that latest map 3 log even though Map 6 was significantly higher boost. Just run that Costco gas down and fill up with best name brand gas you can find...

Oh...yikes...that pull looks bad...stay off of the pedal for now! What if anything did you do differently fuel wise? The ign1 field shows 0 timing advance through most of it. Likely you would have...

Yes, 44 is max trims on our platform...it's OK to see it in your logs as long as your AFR is holding in a normal range. The log you posted is a Map 3 log. Was that intended?

Can you log a fresh pull on Map 5? I see what you are talking about in the AFR, but that was JB4 fuel wires kicking in hard (fuelen field) as values are reading 100. Your trims are low at that...

The logs look fine. Your map 6 is not going to be very effective. You have the plus 9 values low in the RPM band before the turbo is spooled up (so you aren't reaching those targets). Then you are...

Fuel can be inconsistent and varies depending on your region of the country. I would try a different brand. Until then, I would back off and go to maybe map 3. If you do another log in map 3 you...

Timing values (Ign1 field) appear to indicate your car is experiencing pre-ignition and trying to compensate by pulling back spark advance. What fuel are you running (brand and octane rating)?

I really think there is something wrong in your fuel delivery. Since it is on both banks, I would suspect it to be a fuel pump. I would see if you can get both your low pressure and high pressure...

Looks great...looks like Map 5 is doable for you. Wherever you filled up with gas...stick with it. Not all 93 is created equal so I found it is best to stick with the brand that is working for you....

Everything looked good. I would go ahead and post a Map 3 and Map 4 next. These will likely be good as well, but switch back or stay off the throttle until you can confirm through the log data.

Don't worry about the pedal value as long as you are getting 100% throttle when you want it. Logs look very healthy. Trims are maxing so you are getting to the limit on your fuel delivery system...

I suggest you proceed to Map 3 and log again unless your content with...
