Have a 18 Q50 silversport (non redsport) used for everyday driving/commuting. I am interested in adding the jb4 for when I want the extra fun.
What is a safe everyday map. I have 93 octane in my area. Obviously I would post logs after buying, but wondering what people use as a safe everyday map for commuting. Only have a axleback done so far.

Awesome, thanks!

Map 2 is a good combo of power and cautiousness but all of the maps are safe per se. The JB4 won't push the car far beyond what it can handle for extended amounts of time. But as you stated, logging is key.

Map2 is really mild for the SS and a great daily option.

[Jman45]

So how safe would we say map 2 (+5PSI) is? I plan on data logging and i have a SS as well. Just a bit paranoid......

[Silversport22]

If map 2 at 5psi is safe would it be worthwhile to just get a jb1 and set to 5psi (always running 93)? As I mentioned I'm not a drag racer, just want a little more for a daily. A jb1 would also be easy to remove for any dealer visits. I understand there would be no log/ fuel wire/ etc capabilities. As a daily not sure if I would need the fuel wire for Maxing out the motor.

Nothing against the JB1 - I ran my SS with it until the JB4 was available. The JB1 does its job for sure. The JB4 is a noticeable upgrade though. The power comes on smoother IMHO. I run an E30 fuel blend on Map 7 as my daily setting - runs great! Map 5 on straight 93 is my “out of town” standard map. If you need to make adjustments to map settings due to fuel availably then be sure to look at the Bluetooth option - works great! The JB4’s Map 6 boost add by RPM tweaking & rich logging is worth the added $’s for most enthusiasts.

Anyone wii has just LDP’s . Is there any difference in noise inside the cabin ? I’m mostly concerned about annoying drone .

Any performance increase ?
Has the CEL Ever come on ?

I have the AMS LDP and have had zero CEL issues. The WOT engine sound is slightly more pronounced (however I also have the BMS CAI w/ inlets and the turbo spool sound was already there (very happy.)) As for performance - the guys at Jotech in NTX did the work but we failed to do a before and after dyno. If you haven’t already - do the HE upgrade - makes a huge difference in back to back runs (especially in hot NTX!!)

Nice thanks . Does the car sound better to the public , like more muscular/beefier if you know what I mean . As no one can hear the stock sound

Compared to a CBE or ABE - LDP is more subtle sound wise and more about improving performance.

No e30, 93 octane and hot south florida weather. Im new to this, what made you assume i was on e30?

I ran e30 before but was getting alot of fuel cuts.

Other than that car runs great!

Sounds like the same thing that happened with my car, came away from E30 after having the same fuel cuts and the car runs lean, which is what I am assuming he sees on your log based on those comments. I plan to get a lpfp to help with the issue

[Terry @ BMS]

If you have a fuel cut look at fuel pressure in the log to see if it's actually fuel cutting out.

Took the opportunity to do some some spirited runs since I left my keys at Coldstone Creamery last night, hopefully this doesn't cause you to go crosseyed, I changed maps and did a punch of 4th gear pulls for comparative logging.

Opened the map7 and map5 log and they seem OK on fuel pressure. Next time it cuts out try to catch that in a log so we can see what the cause is!

Thanks for looking. The only time I experienced a sputter/jerk was my first pull, which was Map 6. Re-attached. It was around the first time I gave more than 50% throttle.

No obvious indication of the issue in the log. Maybe turn on FUD.7 so target is scaled to pedal input for addl testing?

Will do. Appreciate it.

Just to be clear, do I change the value in the type field to 7, or enable bit7?

[Terry @ BMS]

Click bits, select bit7 on, save.

[Manvj002]

Hello! I’ve heard that running the fuel wires on 91 is not recommended due to a higher likelihood of detonation.. I have them, but have not installed them - does anyone have experience with them on 91? Also, what maps do you guys feel comfortable with on an SS?

I tried searching, but couldn’t find any real answer.

Thx. Done. Logging this PM

[oscars2212]

I have a basic question, so apologies if this has been asked and answered elsewhere in this thread (I really did look).

I have a 2018 Q50 RS, and want to use a BMS tuner without any other mods to the engine, and running with 93 octane. I don't intend to max out performance on an otherwise stock car (this is a lease and is still in warranty period), I just want a modest boost to power.

My question is whether, in my case, there is ANY benefit to using the JB4 vs the JB1?

thanks!

[Terry @ BMS]

Yes JB4 is a better tune, I think it's worth the extra $100. But Stage1 would be much better than stock for you. Just comes down to your needs.
