If you're using a MAC BMS does not support that. There is a 3rd party app posted that people use but you'd have to contact them for support on it.

Hey Terry can you DM me I have a question about firmware for Map 6 adjustments

Hi Terry, so I put back 94 octane gas and it’s definitely better. Could you take a look at my logs? Map 6 is based on Stillen tuning on turbo efficiency. Which map should I run long term for turbo longevity or doesn’t matter? Which one you think give the best performance? Thanks!!

Would fuel open loop have any impact on our trims?

This motor is full time closed loop with wideband O2 correction. Yes it would affect trims but it doesn't happen unless there is a failure.

Hey Terry can you take a look at this new log? Installed LDP's yesterday and did this 4th gear pull. Let me know if you think I should make any changes.

No it's not relevant to this platform as we're not intercepting the fuel pressure signal.

Seems fine to me!

Hello, changed my map 6 and it's somewhat aggressive, can someone check this log to make sure its ok?

[g0ldm4g3]

Hey guys, long time lurker and finally pulled the trigger on a jb4.
Below are my logs for a 0-60 and 4th gear pull with my Map6.
Something that I noticed is that my launch isn't that good, it bogs then goes as opposed to just... Going? Lol I'm a 2017 Q60RS AWD. Lmk if it's safe to increase my boost or just let it be and add bolt ons to allow more boost
My boost profile is tapered, starting from 1 psi to 5 psi at 4.5K RPM, then after 5K it's down to 0psi at 7K

Map 8 is for water meth injection only, did you install a kit?

Doesn't look bad, make sure you turn on both channels of boost, AFR,and trims so you can make sure both banks are behaving properly. I'd leave boost alone and add some Bolton's and relog. As far as launch, with the stock tune it's tough to hit a good launch because of some of the throttle nannies. Anything above like 2-2.5k will trigger a boost/throttle cut.

I am not sure if this information is also relevant to the silversport as well. What do you mean by turn on both channels of boost, AFR and trims?

If you are bogging off the line more boost may help. Might be better off with our map2 here.

Just enabled both banks of AFR, boost, and trims and they're both similar like the graph Terry just posted.

So what's the point of both boost bank parameters if ECU PSI is the actual PSI the car is outputitng?

Ecu psi is the boost the car THINKS it's outputting,before the JB4 adder. And you want to see both banks because it'll tell you if 1 bank is having turbo issues or a boost leak, etc.

There are logged parameters for the left and right banks of the motor for AFR, boost,and fuel trims. It's important to read both channels to see if either side has a boost or fuel problem.

Lol np. Your timing looks ok. Do you have fuel wires turned on? Your trims are maxxed big time and it looks like the AFR leans out in the lower range of each gear.

Yep fuel wires are on and enabled, I seem to always have maxed out fuel... I wonder if they are not functioning properly

Try a run on lower boost. If they don't flatline the AFR then they're not active or making a good connection. If they are then you're really leaning out down low and should drop the boost down there....or time to consider a meth kit

AFR is fine for the fuel but the target is rather high. Might be better off with a lower target. Use dragy to figure out what offers the best performance for the particular situation.

Anything new in the works for this platform???
