TSC sport mode different injection tables ???

[Harvey]

Hi, I've come accross a forum thread where a guy asserts that VSC sport mode (VSC, not AT) changes the ECU program and uses a more agressive injection/advance parameter table... he claims to have worked on this himself (don't know in what context). Others in the same thread confirm this and claim the torque dip is less noticable in VSC sport mode than in normal mode.


Any echo to this around here?

No

If it does its very minute feeling. I sense a change between full tank and empty tank. If vsc does something to speed its negligible compared to how much the tank has in it

That guy, like me after BBQ Thursdays, is full of shit.

It probably feels faster, because the aids aren't cutting in as much.

This post (14th of the page), sorry in French, but google should transate OK:


Je persiste et signe.. Il y a deux tables de réglages de l'avance (ça c'est sur j'ai participé aux paramétrages), deux tables sur les ouvertures injecteurs et angles de cames (Kevin m'en a parlè). Les deux tables de réglages d'avances sont différentes. Une plus agressive que l'autre. Mais, si ma mémoire est bonne, il n'y a pas grand chose. Sur ma titine, j'ai de meilleurs résultats en mode sport qu'en mode normal. C'est pas moi qui le dis, c'est torque pro.. C'est du au fait que nous avons optimisé les réglages...
Voir Kévin pour de plus amples renseignements...

Think bout it, when you fully turn off the TC & VSC, does Sports Mode stay on?

Yeah~~~ wouldn't make sense for Toyota/Subaru to make Sports Mode better than normal mode, but when TC & VSC is off, Sports Mode won't turn on.

"I persist and sign .. There are two tables of settings in advance (this is on I participated in settings), two tables on the injectors opening and cam angles (Kevin told me about it). The two tables are different settings advances. A more aggressive than the other. But, if my memory is correct, there is not much. My titin I better results than in normal mode sport mode. This is not me saying torque is pro .. This is due to the fact that we have optimized the settings ..."

Limited understanding here, but I have yet to see anyone in our Software Tuning forums mention anything about differing timings for VSC. Yelling "PPPPPPPOOOOOWOWWWWWWWEERRRRRRRRR" in your Clarkson voice probably gives you more power.

Thanks for posting the translation, it's pretty understandable... about "torque pro" (wharever that is) he says "it's not me who says it's different, it's torque pro" (I assume he claims that he has some measures with "torque pro" that confirm his sayings).


Anyhow, I also doubt about this, although I've never used VSC Sport Mode or TRC Off myself... I find the back kicks around enough in standard mode!

@Harvey thanks for the link! Interesting forum you have there :-)

Torque Pro is an Android app which connects to an OBDII Bluetooth dongle.
Very useful for a lot of things, proving unicorns exists is not one of them.

I would doubt a dyno-chart as proof of this claim until there was a second independent dyno chart posted.

Salut Harvey, j'ai posé la même question par ici: http://www.ft86club.com/forums/showthread.php?t=24911

Still no definite answer, it seems.

Hum.... the last post is pretty assertive:

There are different drive by wire throttle maps for normal and sport mode. And yes, the throttle/engine mapping is different between the two from the factory.

Obviously being the last post doesn't mean it's true.
