JB4 Logging, stacking and Map 6 Discussion

[shovelhd]

Attached is a Map 3 run on a manual stage 2 Golf R running PetroCanada 94. Is there any running room if I made a map 6?

You're pretty close to the edge. Sure, you could probably smooth things out a bit with a conservative map 6, but watch those IAT's. You don't have much room. They're pretty low right now. Summer is coming.

Overall advance is low. I'd try map 2 as a reference before moving on.

Hello everyone heres a log i took today i was wondering if i could get some help on making a map 6 mr.diggs24 helped me out on a awesome map 6 before that one contains a mix of e30. Was wondering if i could get a map 6 with the same power. Without e30 is it possible? https://datazap.me/u/deurohatch/map3-93-oct?log=0&data=1-4

Probably not going to get the same power without the E. It’s getting hotter and the E does a wonderful job of helping keep things cooler. I run my 93 tune on E30. When I don’t have access to E and run 93 I can tell/see the difference.
Just my $.02

At what point is the IAT too high?

 

[TheMechanicDude]

20+ over ambient isn’t good. Down here I get 30+ sitting in traffic. Intercooler with any tune is the consensus.

 

[Chogokin]

When I'm sitting in traffic I'll see +30. Soon as I get on the gas it'll drop to 8 to 10 above amb. Daytime temps have been in the mid 70's to low 80's recently.

Hey guys, new here! I just started logging Map 1 runs and found one of them hit 26PSI, isn't the max boost for map 1 lower than 26.1PSI?

 

[TheMechanicDude]

Car will hit that. Was boost safety set at? Under settings screen

 

[bostongeorge]

I am going to check the setting when I get back to the car, I was just running stock Map 1 settings. My thing is I did not think the stock ECU would ever hit over 20PSI? it was hitting over 22psi with a 4psi target. I also have not been able to repeat it yet.

It is trying to reach torque targets even if it is heatsoked, I never saw 22psi but 20 a few times.

26psi on Map1, doesn't seem possible unless your car is tuned and you're stacking.

Can somebody with more experience than me take a look at the logs and let me know what you think?

I have a 2015 mk7 GTI. The engine modifications are: JB4, 3” catted Downpipe, FMIC intercooler, inlet elbow and tube.
I did 3 logs today with these Map 6 settings (I lowered them by .5 from the cold weather settings I had to avoid issues in the heat):

1500 0
2000 2
2500 3
3000 3
3500 3
4000 3.5
4500 4.5
5000 5.5
5500 6
6000 6
6500 5
7000 5

The weather was in the high 80’s and fairly humid today. Can you please take a look at the logs and let me know if they look good (and safe for track use), and also if you have any recommendations to improve them. I want the tune to be safe for the track, in hot weather.

I am using additive boost as of now. What is the consensus on using target boost? Is it better for weather variation, or worse? Will I benefit from using target boost?

Thanks!

It won't matter can't max for both summer and winter because the gas is different. Can't run as much boost in winter, maybe the deep south doesn't change blends but everywhere else will. I can run almost 2 extra psi in summer on the 1.8.

Yeah that is what I figured, turns out it was jumping on shift. Working with George to correct the issue!
