its something to do with the fuel level in the tank as you are cornering. iirc. fuel pump , fuel pressure, etc
there are other posts on here about this issue. your have to do a thorough search

Carburettor car converted to injection? The tank may well not have the swirl-pot that the pick up pump sits in.

I don't think so. It's an 87 325i just had a brand new in line pump put in. I've had the injectors cleaned and the rail off. Would the fuel pressure regulator affect it?

Does filling the tank more than half full cure the problem?

No tanks full still does it. Its like something blocks the fuel because I have no power for about 2 seconds

A lot of cases like this turn out to be a split in the convoluted air hose between the AFM and the throttle body opening up as the engine moves on its mounts.

I had a very similar situation last year but in my e46, but the same "could" apply to you.
The exact same simptons were there and I thought my auto box had gone and then in the end had the abs ring on the drive shaft replaced with the sensor and all was well.
Things were confusing the "systems" and threw soooooo many red herrings that it took me a few weeks to sort it out .
Worth a thought.

I'm afraid you're on a bit of a red herring here! Nothing that clever in E30 electronics - the engine ECU is the engine ECU and the ABS ECU is the ABS ECU. There's absolutely no communication between them whatsoever.
That all changed with the introduction of a CANBUS, when designers started interacting different parts of the car together, for not much apparent reason other than they could.
Got involved with diagnosing a problem on a Merc. a few years ago, that had very poor response to the throttle pedal. Turned out to be some problem with the brake light in one rear cluster, leading the engine ECU to think that the brakes were on all the time.
