Semi auto euro is faster. ;) (experimenting)

Not upset at all ... sorry if I offended.

thanks

i have a tiptronic fto and euro luxury auto

my fto readlines 8200rpm i time it to be 7.5 - flat 8 sec

my euro readlining it at 6800-7000 gets me about 9 seconds or low 9's

because both cars are auto you cant launch it like you would in a manual so get a slower time

The gearing makes a bigger difference in the 6mt

I don't have one, but apparently the auto will also "learn" from the way you drive it. Wheels had one as a staff car and were giving little reports on it at the back last year. They started driving it hard in the car park and after about a week or so they shaved over a second (I think from memory) off the sort of times it was running...

That is the ECU - and is the same with the manual.

So, theoretically, if all Euro drivers drive like maniancs, all day, every day, our cars will eventually do 5 second 0-100 k runs? thatd be the day

Ahh no.

There is a variance but hard to say how much and where the actual low or peak points are. My car dynoed 3rd gear at 120kw (probably peak). On same dyno 5 minutes previously - another Euro 6mt got 101kw (probably low point).

That gives you an idea of how the ECU can halt proceedings if it wants. From my crude understanding of the Euro ECU it is very advanced and complex. It is always making fine adjustments to air/fuel ratio, etc. I heard the RX8 is similar - put it on a dyno and "only" gets 125kw because the ECU is confused by the rollers.

I (now) think dynos of the Euro are worthless - you can never get an accurate base to compare it to. Try 5 runs and you can get vastly different results.

dyno numbers varies from car to car, engine to engine.. and if the dyno machine is a roller based, then the size of the tires, how much grip the tyres can manage to grab on the rollers, etc, etc.. quite a few factors, sufficient to change the dyno numbers significantly.

I second that! But will still dyno after each mod cos I'm a silly fool who must like wasting $75 :D

Yeah but it is more than just car to car differences - the ECU is also making adjustments.

When Euro77 had his VAFC installed they did quite a few base runs. Even with the base runs there was lots of variance.

Euro77 - correct me if I am wrong - but your base runs in 4th ranged from 103 to 109 - or thereabouts. No adjustments to anything.

That is a fairly big variance - so how do you know on any particular run whether there is a gain if just stock you can get such a range?

Anyway - we are getting a bit off topic here.

Do the dyno peeps think its weird having all the little euros on their machines after all the brutes in the clone after clone gen 3 flacodore? :)

Id like to dyno mine after I do all the mods.
