- Says it kills power mid-slide if you hit the limiter, resulting in an unexpected directional change and/or looping the car due to the short
wheelbase.
- ECU will not allow a brake stand style burnout.
- ECU pulls power when trying to shift quickly (without flat-foot shift mode turned on) in an attempt to save the clutch.
- Hitting the limiter cuts power significantly as opposed to modern ECU's that lets you bounce off of it.
- ECU won't allow the engine to rev up quickly in neutral when stopped.
Some of this is not ideal but you get what you pay for as this is why it's cheaper than the Supra. |
You seem to have missed his note about being extremely hard on the Z and it never overheating. What it can handle on the track waits to be seen.
The issues noted mostly sound like the typical conservative Japanese safeguards/nannies. I imagine tuners will figure out how to fix those issues as these will be drift machines for many.
As late model BMW 6MT owner (M235), I can attest to the fact that BMW is far from perfect and has gone to great lengths to deaden the manual driving experience and save the 6MT from damage.
For example, BMW has using clutch delay valves in their 6MTs for well over a decade now to reduce driveline shock on hard shifts. The delay valve results in very inconsistent feel and many of us have replaced the stock slave cylinder with an E series slave that has no delay valve.
Also, many M2 6MT owners report severe power delays on hard 1-2 and 2-3 shifts even with all nannies off and on stock and modified cars. I've felt this with my M235 on occasion, but only with certain tunes.
Lastly, only M cars are really designed for hard track use, more specifically, they have upgraded oiling systems and baffled oil pans to handle sustained high G loads as well as upgraded cooling systems. You definitely would not want to take you're non-M BMW on a track with sticky tires without addressing the oiling system or else you run the risk of a spun rod bearing.
I also watched a 2010 911S at an HPDE event last week blow it's motor (likely a head gasket).
No car is perfect.
