Title: MED9.5 - Numbing stock fuel cut limiter throttle and timing
Post by: drbluetongue on September 29, 2022, 10:53:48 PM
Hi there,

I'm wanting to try replicate 90s Nissan style bouncing fuel cut rev limiter on my 1.6 FSI. I'm not interested in ignition cut flamethrower stuff.

So far, I've read the FR and am a little confused.

CWNMXMD :
Bit 2 = 1 Initialize the I component with a value greater than or equal to miistoar_w.
2 = 0 Initialize the I component with miistoar
Bit 1 = 1 air path intervention only with external maximum setpoint speed specification (B_nmaxred = true, suppression and
ignition angle intervention possible)
1 = 0 Air path intervention is enabled.
Bit 0 = 1 ignition angle intervention only with external maximum setpoint speed specification (B_nmxred or B_mdkg equals true)
0 = 0 Enable ignition angle intervention depending on the control difference (dnsi_w < DNSOZW)

My CWNMXMD is set from factory to 0.

If I set
DNSOZW = 0
DNSIAB =0

Is this enough?

Set bits 0 and 1 of CWNMXMD, and it should be enough.
You'll get a rough sequential fuel cut limiter.

this is interesting i will be testing it later as well but for the annoying pop and bang reason lol.
