Agility Mode TCU tune - Shift delays left in shatters!
Agility (A) mode
- Much much much faster shifts, definitely a lot more forceful. I didn't reset the adaptations so the obvious bump on gear change might improve over time. It isn't uncomfortable at all, just my head was slammed into the head rest (in a good way) at redline shifts a few times. Lots of grinning.
- It is more likely to shift to lower gears when you *partially* plant your foot than the old S mode. I found that the stock TCU frequently wouldn't drop gears unless the pedal switch was activated.
- I still had the occasional scenario when it didn't drop into the lowest gear possible (used 3rd at 2900rpm instead of 2nd at the highway onramp) but I didn't activate the pedal switch ie 98% depressed pedal rather than 100%. Still heaps better than stock overall.
- When you use the paddles in A mode it actually does what you want. I found at regular cruising the stock TCU would wait sometimes 5-10 seconds before going into 4th gear, now it will do it straight away (as long as rpm high enough of course). The stock TCU seemed to love to ignore your upshift requests. Hugely better than stock, it is worth the money for this behaviour alone.
- I did a burnout all the way up a hill, smashed into 2nd and kept going with no traction.

The TCU makes the car a completely different animal. Before I never had an issue hooking in 3rd. I also had a bog at the 2-3 shift that was awful. No way to tune it out but the TCU cleared it completely.
I got so used to the bog that I found myself rolling in early to beat it. Now it just spins. I have gotten used to it but first couple times it made for interesting looks as the tires spun!

Not trying to throw shade at anyone, just trying to understand things better.

Now for Troy's TCU, as compared to stock, it is a big performance upgrade as so many people here have commented. It resolves all the little annoying issues that negatively impact daily use and high performance function, it greatly shortens shift times, does not miss shifts, does not reduce enigne output at shift points, and it too has the Agility mode which does all the stock features, but also much, much quicker (noticeably sharper),and can be paddle shifted. A mode with Troy's TCU is the high performace transmission package MB should have provided in our cars.

A mode was never on the stock tcu...
Also note,every car will react to different on a this tcu on year,and what mods you have with it.

Not sure the traction control is fully gone as you can feel it come on still at times.
