I can see the issue. Your max boost 1st is set to 19 and with the new firmware its trying to cut 19psi from total on that gear. The way it works now is the value you punch in is the boost that will be cut. For stock first set it to 4 so you can cut 4psi in 1st.

We havent had much demand for something like this so havent really thought of what it would do based on boost. Assuming its something we would work on what psi add would you set per E10 of detected quantity?
i.e. If E20 is present add 1. If E30 is present add 1.5 etc.

I was thinking more along the lines of the JB4 looking for a E value which we can set to trigger Map 6. When the value is not met, default to another map (including 0).

I'll bet if you worked that out, you could sell Fuel-IT / JB4 bundles. The JB4 really shines on the VAG platform when ethanol is introduced.

Also, any idea if I would have an problems installing the Fuel-IT 5v kit on my 1.8 liter?

What are people's thoughts on how much we can push an is38? Right now I'm at +8.5 at peak which is producing 24psi, and tapering down to 20psi at redline, the thing moves out, however in the UK out temperature has dropped massively and I'm debating pushing a little more to take advantage!

Or am I at the limit for stock **?

The fuel-it/jb4 combo with auto-adjustable map settings based on ethanol content would give the jb4 a new edge on other off-the-shelf options. There's nothing out there that compensates for fuel on the fly.

Maybe a silly question but since the first post just says
2014 VW Golf 7 R
2014 VW Golf GTI

Is this the right firmware for the 2019 GTI Mk7.5?

Also what do these codes mean?
3AE7
431A

Thanks!

Oh those are the cars in my signature that I own.

Same firmeware is used for 7.5
The first fault we dont have a translation. If you do read it with another diagnostic tool let us know what it means.
Second one we see on most cars. Its a message that there is something stored on another module on the car. If all works fine then not a concern.

Oh, lol, gotcha!
Firmware updated without error. Man does map 1 pull so much harder than stock, thanks!

Torque doesn't show anything. I bet those were the two codes that are thrown after pulling the battery (traction and something else right?)

Thanks again!

Hi there.

Just recently I got done with the first round of modifications on my 2015 A3 which consisted of southward pipe without feline element, hybrid IS38 and JB4.

Since then I've been doing some logging to eyeball how things are going and I'm just not sure if what I'm seeing is . . . right?

Here are two logs. One on map 3 and another on map 6 with flat boost set at 26 PSI and safety at 28.

https://***********/u/usermcuserface...log=0&data=1-4

https://***********/u/usermcuserface...log=2&data=1-4

What I'm seeing consistently, no matter at which boost level or which map, is smooth-ish boost buildup, choppy "hump" starts at 3800-ish, hits the target at peak, drops (relatively) sharply at 5200-ish, then another choppy "hump" till 6500.

I suspect I might not be looking at what's important or might not have proper knowledge to interpret it, so here I am hoping to get some educated opinions.

Best to email the logs through to george@burgertuning.com and I can have a look at what its doing. We dont use data zap so please send the csv files.

Quick one, feel bad bothering George all the time! What's the highest I can raise the FOL to? I'm having bad lean issues that I'm at a total loss at now tried everything, tonight I set FOL to 65, thinking 60 was the max we could go, and finally got a reaction from the fuel trim, first time it's changed in the last 4 weeks! So, is this ok, can I jump to 70?

Thats what I am here for It can go up to 100 but you will start seeing fuel rail pressure faults (3AD2).

You really are a legend, never known such support from anywhere, just always feel guilty taking your knowledge and advice for free!

So I think I've definitely sorted this now, my trims were flat lining at 36 every pull which resulted in my AFR's leaning out when under peak boost at 23psi! I had my FOL at 55, changing this about didn't seem to change the trims at all, always pegged at 36!

Changed to 70 and every 4th gear pull since has been spot on, trim line follows the added boost line and afr's stay in the 13.5ish range as opposed to the 15-16 range! Yay!

Just to make sure what I'm thinking is correct, the 3ad2 code doesn't hurt anything? It only very occasionally brings the EML on and it doesn't bother me it sitting there, so I can continue like that?

Once again, thanks very much!

The 3AD2 fault is caused from the JB4 over fooling the ECU into thinking the rail pressure is lower than it should be so it can hold more pressure. It doesn't mean that the pressure is actually low but the ECU perceives it as this. Its not something that can cause a issue though when triggering the light.
