Did you set decel fuel enable to redline?

I did but was very minimal burble and as I say from wot is was almost nothing, seemed like to much fuel maybe? I also only get this retard setting it in he lowest load table in base ignition.

Just keep messing around. No one is hiding any secrets from you as you say.

Buster can I send you my bin and see what you think? I have just been out for a drive, literally nothing until drops to around 3400rpm and then it starts burbling, you can even here a change in exhaust tone, somthing shot set right and just can't put finger on it, so frustrating

"Engine decel - ignition retard" I set to more negative so that during decel, ignition would be around 0-5*
"Decel fuel restore" was set to a higher rpm to keep injectors on.
Then the ignition retard hysteresis was set so that "decel" mode would enable almost instantly on throttle lift

Pretty much mimic this except make the RPM 7k for fuel restore

This is all great info Buster and i get it but im running MS41 Still and i dont have these tables available?

Pretty sure all decel stuff is there for 41.1. If the table names have been renamed, just click them all to match them up to the screen shot I posted.

Yes,Decel tables are there but as you say seems like renamed.
there is a little difficulty determine what "Ignition Retard-Change Limitation B" Is as i dont have that table, could it be step size?
Also "Ignition Retard-Negative throttle" is missing, Could this be "Ignition Retard-Decreasing TPS".

I think if these things are ironed out then might be onto a winner,its deciphering the difference in tables with the two versions.

Just match them up. Get a stock ms41.2 bin and compare the table sizes and unchanged values to what is in the screen shot.

Ok, now even more confused, Downloaded Ms41.2 Bin from the conversions thread but loads up exactly the same, all table names are the same as my MS41 .

Sorry. I explained it as simple as I could. I suggest you reread what I posted.

Ok, so yes your right, Took a step back , looked at decel tables in a ms41.2 bin and compared values and look of table to see what matched up and i have sussed it and yes i was kind of right in terms of what they are named in the MS41.1 tables so i do as you say have access to all of these tables. I will amend tomorow and see how it goes. For now i am off to bed as i have been spending most of the day stressing about this, Very helpfull Buster and i will experiment further tomorow.

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.

Do logs verify that fuel injectors are on above 4K?
