So I ran all the new settings this evening, massive amount of burble, pops and bangs but again only from around 4Krpm and down. its so so strange. im really at a loss as all the settings seems good but somthing somwhere is not activating that decel map or a setting isnt activating untill 4krpm :( i gave it my best.


I'm silently crossreading all the MS4x sections here, to find differences in the ecus and I discovered, that I have exactly the same issue on MS43 and M54B30 engine.

Everything works fine, until I get above 4k rpm, then it starts rev hanging instead of injecting and then normal deceleration.

What does your "Detection - Fast Decreasing TPS - Min. Load" look like? :)

so if i therefore make the load around 75 then everything above that will be "fast decreasing" ?

So you're on MS41.0 ID41 then. ID41 has been made to be very 'mellow' and not sporty. But it can all be changed, even in ID41.

Doesn't hurt to try that setting.
I've been experimenting with this map lately, in understanding how each setting affects behavior.

And don't forget "Detection - Fast Decreasing TPS - Min. RPM". I set mine to 0. Yours is 4096rpm probably.

Exactly this, i will change this and see if it makes any difference, have you messed with "throttle gradient" and "RPM Gradient" ?
I am also setting "Fuel Enleanment" to 0 throughout to see if that makes a difference aswell

This is a vid running the setting i was discussing with buster on page 13-14 , still no pops or bangs when moving until i get down to roughly 4krpm, I have added fuel in the lowest load table in base fuel from 7k to 3800rpm as the lowest load is where it sits on decel and here are the results, why can i get the decel tabels to do more?

EDIT>>>VIDEO WILL NOT WORK, RR WILL NOT ALLOW ME TO ATTACHED MOV FILE DIRECTLY EITHER, SORRY GUYS :(

So i was speaking with Jim today who basically created the shark injector.
He says there are two tables that allow you to basically fully manipulate fueling on decel, therefor would solve my issue,they are as follow.....
==============================================================================
Index: 48
48: Drehzahlschwelle SA
KF_NMIN_SA[U/min] = f(TKW[°C])
==============================================================================
(00011D66H) BYTE "kf_nmin_sa__tkw"
TYPE:"ROM"
DIMENSIONS:[6,"sstm_tkw_1_6"]
CONVERSION: LINEAR [0.000000,00000000H] [8160.000000,000000FFH]
ATTRIBUTE: F="%5.0f"
EF="4ASPManH"
T="NMIN_SA"
I="00000001H,0000000AH"
D="00000064H"
G="00000064H"

NMIN_SA [Hex]
TKW [Hex]
@011C44 18H @011D66 32H
@011C45 33H @011D67 2AH
@011C46 4DH @011D68 24H

@011C48 90H @011D6A 20H
@011C49 B8H @011D6B 20H



==============================================================================
Index: 49
49: Drehzahlschwelle SA und RL_KK ein
KF_NMIN_SA_KK[U/min] = f(TKW[°C])
==============================================================================

CONVERSION: LINEAR [0.000000,00000000H] [8160.000000,000000FFH]

T="NMIN_SA_KK"
I="00000001H,0000000AH"
D="00000064H"
G="00000064H"

NMIN_SA_KK [Hex]
TKW [Hex]
@011C44 18H @011D5E 32H

@011C48 90H @011D62 21H
@011C49 B8H @011D63 21H

Im a little lost when it gets to this point but someone may be able to shed more light.

Yes those are defined and as I said previously that if you want bangs and pops set those past the rev limiter. So nothing new :D
