Thanks Payam. Will the fuel wires help with preventing the issue on map 2 or 3 or am I at the limit due to octane 91?

You're at the limits of octane right now.

Curious how the Red Sport (high-output) is able to use 91 octane and get better performance than the low-output motor. What is different about it that allows it to do so?

Looks okay from what I can tell. You have the fuel wires installed?

No, i dont. i was considering doing that next but was not sure at what point it was needed since e85 mix should lean out the mix a bit anyway right? and when looking at trims from the JB4 isnt 50 maxed out? meaning its trying to add all the fuel it can?

I'm ready to stop modding this car soon and just make it look good until the lease runs out. I got new tires and now my 0-60 is much worse even though I am dead hooking. My logs don't appear to even capture correctly. Nothing sounds wrong, no idea where to troubleshoot or of I even need to at this point. Met up with an Ecutek Red Sport and he obliterated me like I was stock. Not sure if any of these logs will help but they are attached regardless if anyone can look.

Logs are too short to see much. Have logs combine in to one log and do a longer full throttle run to evaluate it.

My exact point, at least 1 of those logs should be at least 20 mins of data with multiple WOT data through multiple gears. Can't even get logs to properly capture, much less the car to move quickly.. I quit for now

Are you relying on the WOT to turn on the logging? Why not manually start the log before you go wot and see if it catches your issue?

I'm manually turning logging on and it doesn't capture properly.. literally nothing is going right lol

I don't think I got a proper log ever since a few months back when i selected the option to combine logs from the same day.. now I disabled that option on the latest app update and still no good data. I just hope the car is running alright.

That almost sounds like a bad OBD2 connection. Can you monitor all your parameters in real time?

They all say runs(1) indicating each one just captured a single run. I do see one longer WOT run in the last log I missed last night.

Yea, was having an issue with that but resolved it by reinstalling every connection point

Thanks, Terry. I'm going to attempt another log today, I may uninstall and reinstall the app before that just to ensure it's not something I did in a setting at some time.

With the JB4, once you set a map it will stay on that map even if you unplug the odb2 connector correct?
Obviously wouldn't be able to see gauges & do other stuff with the app but wanted to confirm how it operates if the odb2 is unplugged.

Hi All, new to the forum and recently got the JB4 hooked up and recorded some logs. I am 100 pages through this thread and hope to get all caught up by the end of the week.

@Terry could you take a look at these and see if you notice anything I should be worried about. I noticed some lean AFRs at some points but not sure if that was the lean boost spool I saw mentioned. Also, I do not know what exactly I am supposed to be looking for in the ignition timing and trim numbers.

I have map0, map2, and map5 logs (last # in file name)

Thanks

Map 2 looks better than 5, what fuel are you using? You will need more octane for map 5 from what it looks like. Other than that, everything looks normal.

What specifically makes you say that? I'm actually on 93 octane (bad gas maybe?) Figured that would be adequate for map5. I have e85 locally, could give that a try sometime this week.

Slight timing pull and lowered timing overall in map 5.

Splash some e85 in there and get another log so we can compare.

Added ~4.5 gallons of e85 to make it a full tank with 93. Attached logs for map5, looks like the first one has some timing pull around 4700rpm. Do the second two logs look ok?

Default log check - 03-25-2020, 09:53 PM

Hi,

Can you please check my log.

I feel like there's something wrong with power delivery. Albeit, this was one of the better pulls.

Acceleration is inconsistent and feels like it's being held back(restricted and is more noticeable and frequent when trying to accelerate while already moving) and often delayed (maybe turbos, ecu, something ignition related?). Conversely, when the power is full on, it feels like something is slipping (almost like a clutch slipping feeling). Also, when i have the jb4 open/connected while driving, after accelerating hard and letting off, the AFR maxes out at like 24-25, is this normal/ok?

I just had a 2016 Q50 RS AWD for 3 years, and never experienced any of these issues. The issues with the current car were there before and after mods/jb4.

For reference, I'm in NYC, weather was around 40-50's sunny, low humidity. I've had the car for 3 months now, broken in (easy driving) for first 800 miles. Have about 3,500+ miles now. Happens in all driving modes, even after trying to drive "aggressively" with the throttle to have the tranny/engine also be more aggressive, but still so inconsistent and issues with power delivery. Running 93 pump.

Thanks in advance.

No throttle = no fuel.. the AFR is normal.. I can't read logs so I will let others chime in

The only issue I see is timing advance is really low as if it's on really bad fuel. Sure it's not filled with 87 octane?
