What's the deal with the TCU on these cars?

I know this is a bit off topic however Are any of you guys with turbo upgrades running a lightweight wheel / rotor setup? Based on the subpar improvements ive seen with the turbo upgrades I bet a lightweight set of wheels and rotors will make almost as much as a difference .

I just was just trying to say I think it makes quite a bit of difference and its something that gets overlooked alot more than I realized. I made this mistake myself. A good real world example of this is comparing the new MustangGt350 and the 350R same motor/tranny/suspension but the GT350R has Carbon fiber wheels and runs 0-60 .3 faster

If it's the exact same failure then maybe we could learn something to prevent it happening to someone else. Anyway Inshaallah I will find a way to get ahold of him myself.

His engine failed at 5000 miles and so did mine. So there's no reason for him to find it weird that I'm interested in talking to him.

Lighter rotors will make a very minor difference in acceleration and braking. They will substantially improve suspension compliance. The further the unsprung weight reduction is from the center of rotation, the more it will improve braking and acceleration. Lighter tires and wheels with very light barrels will make a significant difference in acceleration and braking.

Numbers obtained by vbox not on a track. Could be going downhill. Could be that he has figured out how to do his w.3 to actually work. An actual track time would be much more convincing - there's no potential for other variables.
In any case if you rely on weistec calibration you will not get those times. Why else would Fairbird have to recalibrate on his own??
2 weistec e63s, 1 shop car and another customer car, both lost to renntech intermediate tune + down pipes e64 at shift sector 1/2 mile roll event. Renntech e63 did not have the full exhaust like weistec e63, renntech car had severely restrictive factory turboback pipes+ rado downpipe and pump gas tune. Weistec cars has ice tank, intake full Boltons. Weistec exhaust replaces the restrictive Factory turbo back pipes with much bigger pipes that don't even fit with the factory motor mounts requiring their own low profile motor mount
Now somebody explain that to me

AWD loses to RWD if the engines are producing the same power. Which goes back to my original remark and warning that the W3 turbo performs similar to stock Turbo.

Doesn't matter awd or rwd, car with the most power wins assuming driver doesn't completely suck. Awd can win with less power from stop if it's hard to launch rwd well. Rwd will win up top assuming similar power levels

I have read a few posts about rwd vs awd and sometimes I want to kill a kitten with some of the opinions posted around the forum.

Up top with similar or less power AWD will always lose to RWD.
The question is how much extra power in this case would AWD need to outrun a RWD from a roll.
Ive always wondered how much higher the drivetrain loss is with the 4matic 33/67 they use vs RWD.

i agree but it's one of those things that's hard to gauge.

one of the problems with all-wheel drive and the staggered setup is a difference in rolling circumference which will add to the drivetrain loss by introducing a second element of drag where all four wheels want to turn at the same speed but are forced to turn at different speeds because of different rolling circumference. I don't know how much this adds to the drag whether it's negligible or significant. You can put identical wheels up front and behind or you can use pilot supersports 295 30 19 rear and 255 35 19 front. This is the only combination I'm aware of that has identical rolling circumference for front and rear. 295 will not fit on the factory 9.5" wide rear wheels, Michelin recommend minimum 10" width wheel

about the AWD vs RWD race with the e63 va cls63.
From this video you posted, which I did as well it doesn't look to be a huge difference in drivetrain losses.
Im not sure how much more the staggered tires add but it seems like only a 5-6% difference.
In in this video however it looks like the drivetrain loss is MUCH higher but I don't believe it's accurate. Something seems off because the cls creams the E despite the E having equal weight and extra 20 hp. Let's not forget than in the 1/4 mile there's only a 1-2mph advantage for RWD e63 vs AWD e63 if not anything.
