Is map 1 safe with 89 octane on 2014 1.8T?

Yes, no concerns on the 1.8T.

Today I went to change back to a summer tune and all my old saved tunes are gone. Someone have a good starting point for map 6 with E30 in a stock 2018 A4.

Also had a thought after paying $5.06 for gas today about the possibility of running a 87 and E85 mix and what octane that would result in and any side effects towards tuning.

If you do 4gal E85 and the rest 87 you can run the 93 maps up to map 3.

Hi all.

Long time owner of a JB4 and had it previously on a Seat Leon Cupra ST 290 2016(dsg 6 speed) and now on a Seat Leon Cupra ST 4Drive 300 2019(dsg 7 speed). Really happy with how it works and the maps available.

Running on 95 Ron fuel in Ireland with a custom Map 6 for a while and decided to try out Map 4 with 98 Ron fuel while in Wales (We can't get 98 Ron here in Ireland, Republic). Nice difference between the 2. Tomorrow going to compare how my car feels vs a custom mapped Stage 2 Cupra 2016 Fwd(dsg 6 speed).

Thanks for making such a versatile product guy

Does the auto shift boost redux work for the 1.8T 09G automatic transmission? Seeing some post shift corrections on 3 to 4 shift when logging, tried 50 but didn't seem to change boost at shift.

Yes, it is active. Try increase for a auto since the shift time is far longer than DSG.

Thank you for the quick reply, George. I bumped up auto shift boost redux to 100 and it gave an EPC for misfire and cylinder deactivation my first WOT pull in 3rd to 4th shift. I lowered it to 70, but I'm still seeing the called for 19ish PSI for boost at shift to 4th and still seeing post shift corrections.

Do I need to turn on a bit or do anything else? I'll give 80 and 90 a try just in case. I'm on the latest firmware.

I can post logs of redux 0, 50, 70 and 30 if needed. Car is a 2017 Golf Sportwagen FWD.

Email me the logs to george@burgertuning.com and I can have a look and see what its doing. Send the ones at 50.

B9 A4 tank is ~15 gals, so that's 4 gal e85 and 11 gal 87- I assume this creates somewhere around 93 octane?

I heard that high ethanol content deteriorates rubber inside the car- can I lower the ethanol content by mixing e85 with 91 instead? If so how much should I mix to run map 3?

Thanks

To be safe in terms of octane us 3 gal and map 3 will be fine.
There are no long term concerns with such low ethanol use. We look at markets where they have E30 at the pump and the cars do not have different components int hat market as use to be the norm in the past.

Hey guys! I just got my JB4 installed in my '18 Golf R. I'm currently running map 1, making my way to map 4. I'm in the Northeast so I have steady access to 93 octane everywhere (although I suspect not all brands are the same).

I currently only have a catback but I plan on doing maybe an intake and dp - all tbd for now. Do you guys have any recommendations on what I should do? Should I make moves to try to get some help w/ Map 6 or should I just run the default maps for now till I'm more finalized on mods before getting a custom map 6 done? Or is it not really that complicated that I can change it all the time?

Thanks!

Run up to map 3 and then shoot over some logs to george@burgertuning.com and we can work it up further.

Question - does anyone know for map 6, the boost settings are we supposed to enter target "total" boost or is that the boost amount to add on top of stock?

Im asking because I see settings from some users in the single digit (0-5)~ but in the screenshots in post 1, it's like double digit which seems like a lot to add on top of stock?

I am using the bluetooth app if that matters

There are two ways to do it.
If the value at 1500rpm is below 10 its additive which means it will add over the ECU request. If its over 10 it will target that as absolute boost pressure.

Ok, thanks!

Is there some way to see what settings the preset maps are?

They are hidden maps. You can see the values by viewing the target value in logs.

Below are the settings we start with when going higher than map 3.

1500 0
2000 2
2500 3
3000 3
3500 3.5
4000 4.5
4500 5.5
5000 6.5
5500 7
6000 7
6500 6
7000 6

If its a 7Speed DSG on a R or a S3 these are the starting settings we use for map 6 which is a step up from map 4.


1500 0
2000 2
2500 3
3000 3.5
3500 4
4000 5
4500 6
5000 7
5500 7
6000 5
6500 4
7000 3

Ok thanks! I'm going to start off with these. Is there a target AFR range I should be looking to stay within?

In map 3, on a gear 4 WOT pull (4000-5500 rpmish) my AFR is around 14.6~ average. I saw some other members trying to hit closer to 12 while under boost?

Sorry if I'm asking stupid questions lol this is my first tune (of any kind)

On spool up and peak boost the car will run leaner and then enrich. It does this as its in max spool mode to get the boost up as quick as possible.
When looking at AFR you dont want to to run lean above 15, when this occurs the AFR runs away and the JB4 map switches or you will get a lean code from the ECU.
The AFR is also load based so the higher the gear the richer it will run. The ECU also uses the exhaust gas temp as a calculator for cylinder temps. If those get hot it will automatically enrich till it deems these temps are safe.

It shouldnt go over 15 when above 4500rpm. IF in doubt email me the logs.

Default 2020 mk7.5 running rich - 04-23-2022, 01:32 PM

I have posted on Facebook already asking about my problems with the gti .I have a inlet pipe /CTS intake hose /afe pro dry filter / CTS ******** /91 octane
The firmware when I updated it the settings came with the fol at 60 and I was hovering around 9 Afr on the pulls and I dropped it to 40 and noticed it pulled harder but I'm still around 11 Afr in 3rd and 4th/5th gear it hovers around low 10 Afr .also when I let off the gas it always reads full rich at 3.8 or whatever I thought it was supposed to go full lean .
Can I drop the fol under even 40 to get it to lean out more ? I'm at approx 2500 feet elevation and maybe that's the issue ?

That log was a map 6 and I had it at 6.5 + I think I can go even more tbh

For this model leave the FOL value at 45.
You can lean out the AFR by lowering the fuel bias. Try make the values 20 from 4000 to 7000 and it will lean it out.
