Like Jon said - at that point it's the car that's turning the engine, so there's zip the ECU can do (unless it could electronically disengage the clutch, that is - or prevent you ever selecting the wrong cogs in the first place, like the SMT on the Roadster) - even if you switched the engine off, it'd still be turning at x0,000rpm..
Would then mapper need to run it richer in those cylinders that get hotter then? Or am I way off base?
You'd need some very trick engine management to do that - I don't know if even the top-of-the-line MoTeC stuff can run individual fuel maps for each injector (though I very much doubt it). You could run a weird-ass fuelling setup, with an RRFPR on each injector, I suppose and then up the fuel pressure (or rising ratio) a little on the lean-tending cylinders.. that might work.
Better off sorting the root cause, though, than covering it with fuelling - redesign the intake if that's the weak spot, or the fuel rail (say, twin outer feed to center return) if that's the weak spot..
(That's all based on my knowledge of other cars, naturally, but it should hold true on the 3S-GTE as well)
