I have to say that the G70 Launch Control is not very consistent.
Try manually shifting at 5,500 or 6,000rpm.

I’ll try that. Most seems to be on the start. 60ft time is 2.27 330 ft is 5.86 1/8 mile is 8.80 @83.49.

Is there a way we can get more boost in 1st & 2nd?

Map6. Try 5psi across-the-board so there is no taper at the top end or go 5.5psi for the lower rpm or something similar to that!

Well with Dragy my 0-60 time on map 2 is 5.31. On map 0 stock 5.73
Temp 105 humidity 35%
Managed a 1/4 mile run at 13.46 @ 105.36
Having lived in the Portland area for so many years and having cooler temps I’m guessing these high temps are killing my times.

Seems like there is so much lag out of the hole even with launch control

Is this the 2.0T or 3.3T?

3.3

3.3

Interesting. As a point of reference, Road&Track ran 0-60 in 4.9, 1/4 mile in 13.4@104.8 stock in 100+ heat. I would think Map 2 would improve on that significantly..

Feels like something is wrong?

You can cut down your 60ft time significantly with an ECU brake signal cut. This tricks the ECU into allowing the turbos to build boost while powerbraking.

I don't recommend it, though. A couple Stinger owners report having some transmission issues after powerbraking for too long (~5+ seconds). Not worth the risk, IMO.

Perhaps try to compare your 0-60 between Map 0 and Map 2.

Look around the Stinger forums and you'll find plenty of guys between 5-6 secs even with LC.
You have to find the perfect way to launch it and then it becomes more consistent!

It's a 4.4-4.7 second car stock. In extreme heat, 4.8-5.... 4 flat with Map 2. The stinger is close but a bit heavier.. I could see a worst case of 5.2 I guess... Getting 5.3 with Map 2 just doesn't add up.

How do you launch in different ways with LC?

That would be the educated guess but that's not the case. All the stars have to align to get a proper launch.
Let your wheels slip a little.
On my 2.0T it took me forever to get to 6.0 from almost 7 secs and once I figured it out, I could consistently get 6.1secs.
It takes a lot of practice. Try on a wet day. That always works out for me.

I’ll try a few different ways to launch in the morning when it’s cooler (if you call 82-84° cooler).

....he said wet day here in Phoenix. You’re funny.

I'm AWD.. No traction issues here.

Logged a few runs. Map 2 seems like it's okay, I think I was seeing some artifacts in my previous logs. Right after, switched to Map 1, drove around for a bit, then logged more runs in the same way.

Map 2, 3rd gear pull to redline (1)...


Map 2, 3rd gear pull to redline (2)...


Map 2, run from standstill....



Above runs felt just fine.

Thoughts: ign1 looks fine, I haven't had a chance to really comb through the spreadsheets just yet, but so far what I'm seeing is just fine. You can see the difference between the target boost on map 1 vs map 2, also the actual boost does get a little higher on map 2 primarily around 4000 rpm. But it's maybe 1psi.

What you can't see on these maps are the partial throttle boost. Again, I really think the biggest difference between Map 1 and Map 2, in terms of seat of the pants feel, is due to the turbos reaching max boost at like 50% throttle when in map 2..

I am beginning to think the reason why Map 2 might be just fine on 91-92 octane is because it's really not putting out much more boost than Map 1, most likely due to restrictions in the stock intake and exhaust design. If I'm right, then my statement implies that after installing certain mods you may need to also increase octane on Map 2....just a guess, though. It may very well run just fine on the same octane.

I will probably just do a custom boost map after installing bolt-ons.

Is that with roll out? I’ve read that can be up to .3 sec

^ I will say this again...and I know what I’m talking about...tinkered for over 5 months.

Map 2 needs good 93 octane. You can run with less...but don’t complain.

Map 3 needs 96...99 is optimal. I run 99.

Map 5 loves 103-106 octane.

Beefer, how much does boost or timing increase on average using 93 octane on Map 2? Do you have some graphs you can post?

No idea. I have various Logs posted on the N54Tech board.

All I know is that Map 3 on 93 sucked. Hesitation...knocking, etc. Once the octane was increased...Terry said everything looked perfect...and the car became a missle.

Map 2 was always run on 93 by me. I have spoken to several Stinger folks...especially to a head engineer in a VA Beach tuner shop that deals with this engine.

what do we think about Map 3 on 94 octane. 3rd gear pull

Too short for any issues to show up. You're not flooring it the whole way. Try a 20-80 run pedal to the floor.
