Good log. Clearly shows your Ignition Timing is retarding fast enough.

Now work on the Fuel Notice, ECU reduces Injector Pulsewidth from 12.5ms to 1.8ms within 200ms.

Remember there are Fuel Enleanment tables defined as well. Stock maybe removing too much fuel too quickly. So reduce the amount of fuel that is removed. There are 4 Fuel Enleanment tables defined.

Stock MS41.2 ECU removes almost 50% fuel above 4000RPM and 500mg/stroke Load. Then the other 3 maps define how quickly/slowly this ramps/decays. Read the table descriptions in the latest version of RR to help you tune.

Or post your 24KB and I can modify it so you can understand what I'm talking about.

Appreciate your reply.
Yes enleanment tables are somthing i should look into,Descriptions seem clear enough and yes i see the percentage removed is pretty full on as you say. if you have for example a stock 24kb with these tabels only modified as an example that would be more than appreciated.

Just post your 24KB so I can see the scope of all your current Decel tables and how my suggestions will play into it.

Here you go

Here I reduced Fuel Enleanment - Decreasing TPS.

Increased Fuel Cut - Hysteresis (both tables) by 4000RPM to keep fuel on at high rpm.

I also reverted the main Fuel and Timing table to that from ID60 since it matches your 2.8L engine.

Post logs from this and we can tune it further.

This is excellent, Appreciated.
I will run it this weekend when the Snow clears and post feedback.

This setting made my fuel stay on all the time when coasting (Iam on MS41.0). What were your results rossi?

Yes, that was the purpose of making that modification...

Ok thanks for the clarification. I am trying to create just a very short burble at high rpm. For me it would be annoying to have it on all the time.

Ah ok. I would also prefer to have a short lived burble at high RPM. More of a 'snort' for a short time between shifts, lol.

Feel free to post your 24KB and I can make some modifications for it so you can test.

I am yet to run it as im waiting for snow to clear

This is the current bin, feel free to comment what you think should be altered.

I reduced "Fuel Cut - RPM Hysteresis (Minimum)" by ~4000RPM to 256RPM.
I kept "Fuel Cut - RPM Hysteresis (Maximum)" at its current value of 4928RPM.

A delta between the Maximum and Minimum 'Fuel Cut - RPM Hysteresis' tables should mean the ECU will use the 'Maximum' table at first and after the 'Fuel Cut - Hysteresis Delay Counter' has elapsed, it will switch to the 'Fuel Cut - RPM Hysteresis (Minimum)' table.

I also increased the 'Fuel Cut - Hysteresis Delay Counter' by ~200 cycles to 240 which is stock for MS41.2.

Please post datalogs of this version. If I'm correct, this should result in the injectors staying on for a brief amount of time after fast throttle lift before shutting off. Once we confirm the Fuel Injectors are behaving as intended, we can work on the Ignition Timing.

Thank you for your time!
Attached are the logs with the suggested settings. What do you think?

When coasting after normal driving the fuel cut was a bit erratic, sometimes it would not engage at all sometimes it would immeadiately. Maybe depending on how quickly the tps changed?

Yes, how quickly the TPS is decreased does affect which tables get used. This can be tuned as needed.

Can you describe which log file had the different erratic behaviors you mentioned? So I can understand the correlation between how the numbers look to what is felt when driving.

143838_WOT = describe behavior, etc.
144020_low_RPM = describe behavior, etc.
144051_shifting_2nd_to_3rd = describe behavior, etc.
