2019 Raptor Tune ?s

[jake.]

Hello,

Looking for some input on this tune for my 2019 Raptor. Mainly working on WOT adjustments at the moment and showing Driver Demand and Torque Airlimit Source as Turbo FMEM. Also Torque Max Source as Wastegate Airflow Limit. It seems tip/load slightly overshoots or desired tip lowers causing throttle closures. Novice to ecoboost platform, am I going about this wrong and are there any other things I should be looking at?

So far I have:
-Raised LSPI Hi, Nominal Limits
-Raised Comb. stability limit
-Slightly scaled 9739 EWG Base Wastegate control - Added last column for resolution of logged exhaust flow.
-Raised 3630 Turbo Airflow Limit
-Added TQ to 78 and 90% columns in Driver Demand table
-Removed 5% torque from 1.90 and 2.20 rows of torque model/Load/Tip and inverse tables to target higher tip.

My E50 tune is a little older, it will not let me compare to yours. Have your entire last row of driver demand 600 ft lbs. Use LSPI high to limit boost. When you hit that it will show popcorn in the log. Put all LSPI back to stock. I attached a picture of mine that got me 230 KPA across the rpm range, Put this for LSPI high. Yours is way too high. Nominal needs to be stock. This will lower boost if you have knock and bad fuel. Raise your cylinder pressure limit, it will take more timing. You will need to get that FMEM out of the way too.Screenshot 2024-04-05 182838.png

Thanks, not sure where the Turbo FMEM is coming from. Compressor flow is under the limits I have set in the over speed table.

How much timing do you think it will take on 93? I'm haven't done much with ecoboost/DI so just trying to keep it safe for now.

This will reduce boost in the event of impact and poor fuel. Increasing the cylinder pressure limit will necessitate additional timing. Additionally, you must clear that FMEM from the way.

It looks like you're making good progress, but there are a few things to consider. First, ensure that your Turbo FMEM and Wastegate Airflow Limits are properly aligned with your Driver Demand adjustments, as overshooting TIP can cause throttle closures. Additionally, refine your torque/load/TIP tables to smooth out any sudden jumps in airflow that might trigger over-boost conditions. Lastly, monitor related parameters like WGDC and Throttle Angle to ensure your changes are not causing instability or FMEM triggers.

There is nothing wrong with throttle closure, it is the best and fastest way to keep boost under control and keep things safe.

If your just making a pump gas file, you don't really need to touch the torque tables. Leave them be. Leave the wastegate tables alone.

All you need on pump gas is increase cylinder pressure limits and let the ECM figure out the rest with timing, increase airflow limit a little bit, max out the temperature settings in the turbo, bump up LSPI HI and nominal tables up a small percentage, add 25-30% to your DD tables at 78 and up, add the same 25 to 30% to your IPC maximum tables, and set your enrichment settings to come on quicker, bump up trans truncation, and your on your way to a good starting point.
