Could you try touching the intercoolers with and without cover after driving?
I found out today that the intercoolers get warm without the engine cover even if the temp outside is 17F. This is also the first time I saw my water temp goes up to 210 F , normally 196 is the highest I get.

The other day, the temp was 53F and I had the engine cover on. When I removed the cover after driving it hard, the intercoolers were cold.

That engine bay is a riddle wrapped in a mystery. I'll keep that mess covered up.

I think I’m going back to full 93 octane (Shell V-Power Nitro) ) - No Ethanol mix. Then add only 15% of E85. I like the cleaner (additives on the V-power) vs Mobile (10% ethanol)
This probably will prevent carbon buildup within the EGR valve route.

Hey all. Can some folks post some of their JB4 settings for a RS? I have tried a few but can’t seem to find one ai like. Getting hesitation around 1.5 to 2k then kicks in too hard

Out of my own curiosity I did as you suggested. At the end of two different "errand" runs, one w/cover and one w/o cover, approx 25 min, 20 mi, street/fwy combo, and no WOT, the intercoolers were barely warm to the touch, perhaps even less warm than my own hand. Keep in mind I drive a non-RS Q60. I also had the air intake deflector off (see earlier pic), but even with it on there's an opening near the hood latch that allows air to flow over the engine compartment. So it would seem the i-coolers stay pretty cool under "normal" driving conditions, but of course your results may vary.

Hope that helps.

I leave the engine cover off normally for practical reasons... I'm always under the hook poking around. But I don't believe it has any performance benefit.

Hey Terry! Iíve been lurking for sometime on this thread. I had a 335 N55 with full bolt ons e85 and jb4. So much fun!

When I purchased the 2018 q50RS I really was thinking just to daily it and not mess around but I heard you had released a JB4 I just had to.

Mind taking a look at my log? Iím running 30% E85 and Map 2.

Timing seems fine and boost pretty consistent. Itís just my AFR that seem to fluctuate. Think Iím running too much E?

Looks normal overall to me. AFR will wobble about at higher power levels at higher RPM, but I think it's due to the smaller turbo and increased back pressure, and not a tuning issue that needs to be solved. Combustion looks healthy so I'd roll with it.

Awesome. *** and cutouts should be in this week. Hopefully the AFRs smooth out. If all goes well Iíll add another pound of boost. Iím really loving the smoothness of the jb4. Feels just like stock just faster. .

Anyone reading this thread thatís hesitant, go ahead and jump on the jb4. Install was like 15 min and itís a great mod for the price. LOVE the Bluetooth control and logging.

Now if someone could just manufacture an upgraded compressor wheel so we donít fall on our face after 5k rpm

Honestly It probably wonít do much on our platform. The stock turbos are already pretty tapped at efficiency. If they werenít the most efficient turbos maybe you could upgrade the wheel to a billet/Cnc wheel with steeper angle blades or slightly larger to provide a little more airflow. But from what I read these turbos are already maxed out in efficiency. You would probably need to upgrade the entire compressor housing which seems pretty expensive right now or just swap out the turbos for something bigger. Which might not be feasible for A long time.

Idk much about the platform yet though so I could be talking out of my ass

So true.. We're working with PURE Turbo who is looking in to upgrade options it.

I also ran across a user on FB who is supposedly replacing the stock turbos for a drop-in replacement that'll be here next month. He wouldn't release any more details.

Hi Terry, could you take a look at this data log?
I rolled on 1st gear (did not mash the pedal) then went full throttle after.
I’m not liking the AFR (Is it just delayed?) I prefer AFR between high 11 andlow 12 on WOT!

Fuel is Mobile 93 and approx. 25% ethanol (E85)

I have a Luxe AWD map 6.
Thank you sir!

https://drive.google.com/open?id=1AO...eEKUAymX6Zy9qa

I would like to go back to pure Shell V-power 93 and 20% E85 mixture.
The E85 looks like it’s leaning my AFR...

I read somewhere that the wheels are already billeted (and probably efficient).

I know that anything is up gradable, it's just that it can be costly. BUT, these are luxury (or semi-luxury cars) and i remember when the G sedans can out, a good SC kit wasn't cheap... so i'm sure there would be some early adopters who would just on the bandwagon to get a reliable 500hp, etc

This sounds very exciting. I would drop in the new turbos. This platform would be perfect with another 50-100 hp up top. It feels like a diesel truck right now. Pulls like a beast from idle to 4500 after that it loses its pep.

How much boost is map 2? 5 psi?

The E85 looks like it’s leaning my AFR...
Mine was doing the same thing. Maxing out the trims with +7 and +6 resulting in low to mid 13s AFR. It's not the E85 either as it was doing the same thing with straight 100 octane unleaded fuel. It seems that either the ECM just doesn't have the flexibility to account for the extra airflow and add fuel accordingly or there's an issue with fuel delivery in general. I was still seeing good timing though but I'm very uneasy seeing those ratios. Have you tested the E85 you use yet? Bad E85 could be lowering your octane. In the mean time try +5 instead and post some logs.

On tip in it's going to take a second or 2 for AFR reading at the sensor to catch up, plus the ECU runs a lean spool mode to get in to boost faster, so looks pretty normal to me here on tip in. Timing is holding steady.

You could try lowering boost by speed a bit. Ensure you have the latest firmware and interface, as I don't see MPH in the log.
