Is it possible to adjust idle RPM w/o Femto and SW?

[Strat-Supra]

Basically as the title states, I have a 2024 MT and I'd like/need to raise the RPM at idle to offset the resonance induced by swapping the engine and transmission mounts. I wasn't planning on adding a tune or anything as the car has plenty of power for the street, so I'd rather not go through the whole process and funds just to raise the RPMs at idle.

I suspect it's the only way but I'm hoping maybe someone knows a trick.

No.

As others have said, not possible without an unlock and tune.

supposedly possible via protool/ista, but i haven't figured it out yet

you have tested the ista idle adjustment service function?

That is a service function and not a permanent solution. When you exit the service function, the vehicle will revert to default settings.

is that new for g series vehicles? on f series ista specifically states "permanent adjustment (programming) and end test module" within this service function

I don’t think it’s new behavior. It’s never been a permanent adjustment. I’m not sure why it says that.

Is it possible with MHD?

Yes. Possible via custom tuning with MHD, Ecutek, BM3, MGFlasher.

That's crazy, you can't adjust the idle on your car anymore, that's a serviceable function. Allow adjustments within a bound range to ensure the car still meets regulations and legal what nots.

I was able to do this with protool, permanent idle adjustment, sticky with ignition cycles etc

Please create a DIY guide for this. Thanks
