Don't fucking disconnect your MAF. Limp mode alpha-n is there to get you home, not run 10 sec 1/4 miles.

Ridiculous. Do you want a running car or not? There is no reason for your MAF to "go down", whatever that means.

Hello Everyone.

Theres a friends Mk4 R32 that he wants me to implement Sparkcut on.
I have done this on my own 032TL.

But I cant seem to find the correct conversion (or address) for RPM axis on KFSZT

Other settings:
FTOMN = 0.2
KFTSRL last rpm row stepped and Zero'ed
DNMAXH = 50rpm

Attached is a screenshot of KFSZT, Address and Conversion.
Please help me understand if its the Address or the Conversion that I am not getting.

Thanks gents.

It's possible to implement it with soft limiter about 4k-5k rpms?

I check this version and works fine, maybe this can work with lower rpm (NMAX - 4500? NMAXOG - 6800) limit below some km/s (VNMX)?

KFSZT doesn't exist in MED9. You're looking for KFTSRL

On a Golf 4 2.8L V6 AUE 022906023E 354077, the rev limiter has been set using KFTSRL (cut spark 6800rpm), FTOMN (0), all nmax maps 7100rpm, and dnmaxh 0. The rev limiter works perfectly from 2nd gear onwards but behaves incorrectly in neutral and 1st gear. If revved to the limiter in 1st gear, the engine speed limits to around 6200 rpm; releasing and then fully pressing the accelerator again allows it to reach the limiter and trigger the hardcut. The same issue occurs in neutral gear. This suggests there may be a restriction or offset that needs adjusting, but the specific parameter is elusive. A DAMOS file for the ECU is available for reference, so any insights or solutions would be greatly appreciated.
ORI attached
Thank's in advance
