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.

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.

You are new to this and just learning the app and how to read the logs. I was in the same place a year or so ago. Hell I even asked what settings would give me the best gas mileage on here. Users at the time politely told me that I was in the wrong place if that was my concern!

I email myself the logs and open in Excel. Once in Excel, I just shift around the columns in the order I want them in, hide or delete rows/columns I don't care about, and add some conditional formatting for the coloring. I feel like the coloring really makes it easy on the eyes and it also helps illustrate any sudden spikes or dips.

I would be happy to format any logs if anyone ever wants them done, just reach out, either on here, or the Q50 forums!

Map 2 log - Timing looks great to me. Concern is that fuel trim is maxed for much of the pull. In 3rd gear AFR looked a little lean. Later in the pull, AFR richened to what is normal to see without fuel wires.

Map 3 log - Timing looks good. Trims are not maxed as much as the map 2. The AFR is still a little lean in 3rd gear but it catches up to "normal" faster than the map 2 pull.

2nd Map 3 pull - looks great except for another timing anomaly at timestamp 638.75. Ign1 value dropped from 15 all the way down to 5.5. Usually a big sudden drop like that would indicate a knock event. The 15 seemed high to me though and 5.5 is not necessarily a bad number to see in the middle of a pull. Its just the sudden change in the value that is throwing me. The timing recovered quickly to 9.5 and looked normal to me the rest of the pull. Trims were high again but maxed less and AFR looks improved further.

I don't know what to recommend to you at this point. My novice advice would be to back down the E content slightly to help with the trims/AFR. Hope someone from BMS looks at this and can tell you if you should be concerned about the couple of timing anomalies.

Thanks for your thoughts on this. I really appreciate the insights you offered. I am going to do another round of pulls next week when it's time to fill up go with more of an E30 mix. The E85 at my place is at 85% so I will get a better gauge of what I'm really running. Then when I do the pulls I'll make sure the ETC is off. I seem to remember Terry commenting that this makes a difference as it affects the ECU map. I might be wrong but lets see what they look like when the pulls are done properly.

Thanks for the feedback. I love my Q60! Coming from the FRS/BRZ/86 platform it is BRILLIANT to get that pushed into your seat feeling.

Someone from BMS able to review this one? Curious if you have any feedback on the low/flat timing.

Thanks,

Got a small issue.

The Q recently threw a P2098 which is driver-side ruining lean after doing some custom exhaust work to the Y-Pipe. Checked the welds and don't see any leaks yet but I'm hoping it's an issue with the O2 sensor/exhaust work.

Ran some logs on Map 2 (on 92 Octane) below and I'm seeing small AFR spikes for a second or two after WOT. Is the AFR spike normal for a small exhaust leak or is there a bigger issue I should worry about? Never had the spikes before the CEL.

Mods are LDP, HE, exhaust. Logs below

What do you want answered kinda? As long as your car isnít pulling timing and your afrs look good based off the other logs you have sent. Map 6 is for you to add values if your adding values around what you used before itís not going to suddenly change much

Darren Lewis was posting here because we could not figure out if the timing values on his pull were OK. The curve was strangely flat throughout the pull. At high RPM I am used to seeing the value get back to double digits. On times when it doesn't, usually you see knock events in the mid RPM values - I don't see that in his log. This pull it starts at about 8 then goes to 4 and up to only 7 at high RPM. I wasn't sure what to make of it.

Originally he posted this on the Q forum but no one else commented on whether it was OK or not. Was looking for feedback from BMS - maybe its perfectly fine, but was unusual from what I have seen in other logs. I just hang out on here to give new users basic knowledge of how to read their log and try to help them boost safely as they gain their own knowledge. Silent Q has done the same since he joined the JB4 club!

Darren, do you have any other pulls to see if the timing is always flat like that?

Joshhooper, you might want to post this problem on the Q-Forum. Lots of knowledge and discussion over there about exhaust setups and the cars themselves. If you haven't joined yet I highly recommend!

Thanks for chiming in here. Yes, I have many others I have logged and they all do the same thing. They drop to about a 4, then very slowly creep up, never reaching double digits.

Even my map 0 log does the same thing. Dips to 4.5, and never gets higher than a 9.

The dip to low single digits always coincides with the increase in boost, so that does not appear to be knock, but like JCB said, it just never really climbs back up as high as we see on other logs.

If you have placed the JB4 box in the brake compartment. There is a series of ground wires on the front, lower side of this box. Make sure that the wires and box are not in contact with these grounds. These grounds caused a stutter at WoT for me. After Mounting the box on the fire wall all problems stopped. I deleted the logs sadly but they did look similar. Just a idea and what worked for me.

Thanks for the feedback, I will take a closer look when I get home tonight. Do you mind posting a pic of how you mounted yours?

Awesome - figure 20% loss from crank HP to Wheel HP and you are driving a 430HP rated car now!

From what I can see, it looks like you did these pulls in auto. You need to do them in 3rd or 4th in manual. I would recommend 3rd but you pulled timing blow 4 on ign 1 on your map 6. I suspect you didn’t quite have your E mix right, Fuel trim should be around 44-50 being maxed out on your Lpfp and your Hpfp.

I would make a pull and repost, let’s have a look at it after. 2k to red line should give you a good idea of where you are standing. I have a feeling they will look a lot better then.

Yeah, you are pulling timing below 5 all the way down to 3.0. Check your E mix make sure your checking it at the pump. I would try map 5 which is BMSís 7 psi map. It should work better. What are your settings for map 6? I ran 9 psi over on map 6 on E30. Well with in the stillen report I might add and made 430whp.
