Map 2 for the high torque map and map 3 for more linear power delivery if you running 98ron. Worth trying both and seeing which you prefer.

You can use it but it will taper boost at high rpm unnecessarily.

Thanks man. It can now be unlinked without having to attach it to the car. Follow this link: https://www.n54tech.com/forums/showthread.php?t=67481

I have been running our MK8R UK Spec mostly with 95 Ron fuel. Based on the car we tested in the US which also ran 95 the gains where 50hp so there is no long term negative. When fuel has ethanol in it there is typically a advantage when it comes to knock prevention as the ethanol produces less combustion heat. The E10 is actually better fuel than normal 95 with a lower ethanol content.

We have released the JB4 for the Golf Mk8 R and models with the high power Gen4 motor. Had some dyno issues but averaged decent gains in third gear. We will run again once sorted and publish some final number but typically we get customer numbers quickly. The car is a easy 370hp car on 95Ron and 390hp can be expected on 98ron or higher. The JB4 unit is unique to this model due to the turbine speed sensor that showed various benefits when intercepted allowing us freedom with boost targeting. Released maps are capped at 390ft lbs for DSG but I have personally been running far higher torque values to test long term durability through the summer months here in South Africa with our UK Spec R.

Yes, map 2 is recommended for 98ron. In cooler climate its fine to run map 2 though but once temps go over 20C or so switch back to map 1.

The JB4 works by sending lower feedback to the ECU in terms of boost and in turn the ECU targets stock boost and hits it. Fuel is compensated in the same level so fuel trims remain within the limit the ECU allows. Turbine speed sensor is taken car of as well. There has been no change in terms of detection of the years with the Simos ECU hence you not seeing multiple cases of cars having issues online.

Havent seen one like that during my time. If the black wire goes to the bluetooth module then its the ground.

Correct.

Generally when the ECU's are cracked you see tunes come out a few weeks later. The period prior is not R&D as they cannot access the ECU to test changes. This is the general norm with most tuning companies.

Hi Dan, The OBD cable is still needed as it feeds the JB4 with engine data for mapping purposes. The bluetooth module does not replace this function. Is should not have crimp connectors. Can you post a picture of what you have?

The next owner can. It will give a Kit not owned alert when he logs on and he needs to follow those instructions.

We are 6 months into giving our 8 R a good beat down and so far so good. We could have released a product the following day but that's not how we roll. Typically we want to see winter and summer. Our UK spec car is in South Africa and we seeing 34C or so these days. Turbine speed sensor is taken car of

We have the hardware ready for the Macan Turbo we just waiting to get a car in so wont be long. Connect to the JB4 go to Setting then Jb4 Tuning then Connection Settings and click Clear Saved Bluetooth Device.

The bluetooth module is connected to the app on your phone. Connect to it and go to settings then JB4 Tuning then Connection Settings then click Clear Saved Bluetooth devices.
