Default Boost cut or fuel cut on Map 2? - 10-07-2020, 02:00 AM

Tried a launch in my 2017 Seat Cupra 300 DSG with the JB4 set to Map 2. Straight from the launch I had what felt like boost cut or fuel cut and the revs dropped to about 2K before picking up and then pulling normally through the gears.

I didn't have my laptop connected to log the issue but wondered if this is common and if others have seen it? Car is running 99RON fuel so thought Map 2 would be OK?

Cheers,
Rich

If its a 7 speed DSG select map 4 and see if it persists.

Might be a traction event. Try map 4 and see if it persists.
If so then use the boost cut value and lower boost in 1st gear. In user adjustments you will find a parameter called boost cut 1st. The value you put in is how many psi it will cut in that specific gear. Start with 3 and work it higher or lower relative to what it does.

Thanks for the replies George. Not sure it is purely traction as today I also felt the same cut when it downshifted into 2nd under hard acceleration.

Best bet would be to email me at george@burgertuning.com with some logs of the event and I can possibly pin point the cause.
