when im driving around town i leave my car in sport auto with asc on...the other day i was cruising at about 25mph the transmission was in second gear(auto) and the engine was at about 3k...i went WOT just having some fun...the car down shifted to first the rpm's climbed but it missed the shift back to second...the car hit fuel cut,did that jerking thing it does and then slammed into second...i can get it to happen every time under the above circumstances

is it just my car that is doing this or is it normal??? any help would be great!!
thanks

 

at 25mph mine won't let me put it in first gear when in manual mode, sport, normal, asc on or off. Never tried it in auto though.

 

if i knew how to post videos i would...but yeah the car auto downshifts to first and misses the shift back...

 

I've had this happen at WOT in first/sport/auto twice... just slammed into the rev limiter so I let off the throttle entirely and put it in manual mode... I rarely use the sport mode auto anymore because of that, lol.

 

think this has something to do with the ecu learning curve, im not sure how often you go wot, but whenever I reflash I notice I have to ease it in a bit for a while to prevent the exact the same thing. Also, b/c your in canada, maybe the cold weather has slowed shift speeds? So maybe the ecu needs time to adapt to the colder temps with regards to timing of shifts...

but then again, I probably dont know what the hell im talking about!

 

Ok, I'll bite on the ECU adapting to driving style. This happened in the first couple months I had the car and I haven't had it since, but then again like I said I try to avoid that situation now... hermm.

However I don't really know why colder temperatures would affect shift timing (to the extent of allowing the engine to redline without shifting in automatic mode). Maybe someone could elaborate?

 

i think it has to do with auto throttle blip downshift control if you leave it in sport mode it will refuses to go down below 3000 rpm...
