Supercharger Load Limit?

[mrshanab]

I'm getting the Torque source as "Supercharger Load Limit"

First time to encounter that and can't find the relevant table within the tune.

Any idea?

It's a 2019 F150 5.0 V8

What supercharger kit and where did the tune come from?

Interested to know myself. My 2020 twin turbo GT does the same thing. Doesn't seem to hurt anything though

Think it has to do with speed density. Given the ?map? sensor is seeing positive pressure instead of vacuum it normally would so the ecu infers it to be under boost.

Check table 44181. Looks like both the stock car and truck have supercharger engine protection limiter switched “on”.

Its a completely stock truck

Is it actually limiting anything? Is the spark source torque modulation? Is the throttle wide open?

It does not seem to limit anything. The spark source is Borderline. The throttle stays wide open.

It's just something that I've never seen before and was wondering about

Same.

I'm just wondering where the rest of that information is.

I see the supercharger limit in 44181 so when it sees that, where is the actual table that shows the limit it is adhering to?

It might not be defined due to lack of need. You can download a gt500 cal and see all the parameters under airflow->supercharger.

2020 GT500? I don't see one in the repository. Can you send by chance? Would love to dig around
