2018 M3 LR+AB feels faster then 2020 M3 LR+AB

980 motors have a different rotor and different inverter that has about 80A higher load capacity

Sure.

That doesn't address my question at all though.

The performance of the car is software limited, so an 80A higher load capacity if the SW isn't using it gets you 0 performance difference.

That extra capability is why you can use the ghost module (which tells your LR AWD it's a P, not an LR AWD with boost) but doesn't speak to a boost car with a 980 vs a boost car with a 990- which was the actual question (and literally the thread title).

AB is advertised, both by Tesla and Ingenext (via the boost 50) to offer exactly the same performance on 980 or 990 motor cars. scarpiamod3 claimed there's a measurable difference and I asked them to prove it.

Even if you don't have a software limit, You can't get the same performance between 990 and 980 regardless Ingenex or ghost. The inverter is different. The AB for LR WD itself is the removal of software limit.

A Model 3 LR AWD with AB and 980 motor would still perform differently from M3P because the inverter is different.

You seem to keep conflating boost/ingenex/ghost. They're different things.

One (boost-either the AB from Tesla or the Boost50 module from Ingenex- and the actual topic of this thread) does not care which motor you have and performance will be the same with both.

Ghost from Ingenex (or a P from the factory which is effectively the same thing) does care, because the 990 can't take that software at all.

The inverter is different.

That doesn't mean anything unless you're exceeding the limits of the lesser inverter.

Which you're not with boost.

Otherwise AB wouldn't work at all on the 990 and there'd be some other, lesser, version.

The AB for LR WD itself is the removal of software limit.

No, it's not.

It's simply a higher software limit.

One both 980 and 990 are capable of. Again, Inginext doesn't even ask which you have when ordering the boost unit. It's the same unit for both, the same software and the same limit for both.

Identical.


They only ask if you have the 980 if you want the Ghost-- because that further increase the software limit (and even the P/Ghost is software limited it's simply a higher limit) and surpasses the hardware limit of the 990. Boost does not.

A Model 3 LR AWD with AB and 980 motor would still perform differently from M3P because the inverter is different.

UH what?

A LR AWD with a 980 motor has the same inverter and motor as the M3P....which also has the 980.

Only software would make them different so obviously they're be different due to THAT... but swap AB for ghost on the LR AWD and they're identical in performance because they're identical in hardware.


But again that is not even what we are discussing

We are discussing LR AWD with boost and a 990 vs LR AWD with boost and a 980.

Which should be identical in performance because neither needs to exceed the capabilities of either motor.

The better inverter on the 980 only matters if you're going to command performance exceeding what boost offers-- which is only possible with either the Ghost module or the factory P software (which you can also flash onto a 980 LR AWD if you have Tesla-level access, which obviously most do not).

I see your avatar is very apt today

But yeah clearly he has no source for his info. At best I can see the 980 with boost maybe not heating up as quickly. But outside of a potential heat soak scenario, I can’t imagine they’d perform any different if both are commanded to use the same current at the same voltage.
