Any Thoughts on Renntech ECU-Upgraded SL 65 ?

I will give one thing to mercedes.

While their cars are not good in snow and ice, they are still far better than BMW's cars (atleast their RWD cars).

While their cars are not good in snow and ice, they are still far better than BMW's cars (atleast their RWD cars).

Heating and ventilation is better, the E39 windows seemed to mist fast when cold in comparison to an E class. That BMW E39 was very fun to drive in the winter, even with traction control. It had no DSC but only enginecut, I think it was fine as that! Certainly DSC and ESP prevents accidents in the winter, statistics says that. I'm pretty sure my friend who once had a E39 wasn't driving very good. He crashed the back of the car 3 times and the whole side once. It is fun to slide but he don't seem to realise that the rear of the car can go too far making it impossible to save. DSC prevents that.

I also read about something I've never even knew about: both Mercedes and BMW have a differential that when making the rear spin fast, the wheel with traction helps even if the other wheel has no traction. I noticed this clearly some time ago! This was a C class from 97 but I read about it in a comparison test.

That's strange, because in the 90's, BMW heavily advertised their pride in how their car's handled under snowy and slippery conditions, and still do. But then BMW's system I believe activates only the front breaks, while Mercedes-Benz's system "ESP", involves all four.

MB has always been very heavy on safety, it's always been one of their primary selling points, so that explains the greater development of their system. But I equip snow tires to my 740 in the winter and with Dynamic Stability Control, and near 50/50 weight distribution, I think it feels fine.

a BMW can be driven safely in poor conditions, I haven't gotten stuck once, but you have to be good. 50:50 is nice, so is the electric nanny, the suspension is not terribly giving, like any sports car, so it puts more impact pressure on the tires, which simply can't grip. I put deep all seasons on my bimmer in winter, it seems to work ok, but RWD volvos, mercedes, and even lincolns and fords were far better. In the category of worse, RWD Jaguars, ford mustangs, camaros, and the like. It's very tricky though. You have to be all over it at all times, it will slip out from you on the littlest things. It's just not forgiving in snow.
