I went cruising around tonight and i hoped on the expressway around my place and hit it. Ususally if i know i'm gonna wail on the gas pedal i switch it to Sport mode but i left it in Econ and my acceleration past 150k wasn't like it usually is when in sport i can usually glide upto 180 and have little trobule breaking 200 (did it on an onramp today ).

Will Econ mode limit my top end or am i just seeing things, or did my car break?

[slarti]

I dont think the econ limits top end, I think all it does is move the shift points to a higher RPM.

[Gregg]

ECON mode shifts at lower RPM than SPORT mode. But it should have no effect on top end speed. WOT (i.e. kickdown engaged) is the same no matter which mode you're in (once you get going of course)

[bobcat]

being in sport mode will allow more rpms which could give you more boost when shifting into top gear and thus more power.

mines like that, allow the boost to build slowly and it will get to around 16, kickdown hard and you can get 18psi.

Good catch Kevin, no Turbo!

well, i meant that that "bobcat" is boostin 18, and has an 18T...

I run in sport mode all the time because I like the shifting better. Also, I manual shift my auto all the time because I don't like it pulling at stops, and I like the engine braking like in manuals. The braking is no where near like a manual, but better than just leaving it in drive. Also, at lower speeds, L has strange shifting in econ mode.

I haven't fooled around with the drive gears other than D, but i plan to, although i took off holding the shifter and accidentally pressed the button along with some acceleration and dropped it to 3, i did notice that the lights on my Sport/Econ selecter went out.. i wonder if the 94 still has the mode distinction in gears other than D.

I'll have to beat on the car on the way home tonight to make sure she's still all good!

No, the lights go out in all years for the 850. Don't know about the S70. The reason is you are manually shifting, although the shift points stay the same, it just won't shift above the gear you have selected.
If you shift into L from a stop, the car will remain in 1st in either mode. If you are rolling in sport and shift into L, it goes into 2nd. If you come to a stop and don't shift out, it stays in second. In Econ, if you shift into L at around 20 mph, it goes into second. If you slow down, it will shift into 1st and will surprise you if you aren't ready for it. This last one is the main reason I don't like econ. If it just left it in drive, it wouldn't matter.

well i can actually get and hold 19 psi over 5000rpm, but this is again with a hard kickdown and shifting under full boost that causes a jump up to 19psi which holds untill i let off.

As im running a 15g map the ecu will limit boost to 17psi under normal driving, but it gets it under control at 19psi when i build boost fast. even tho im running a 15g map i have been told by my rica dealer that the fueling is good for 18/19psi (short duration). I have also tweaked the wastegate to give near similar spool up to my 15g.

once i have all my other mods done i will get a proper remap with some dyno time.

So lemme get this straight - you bolted on a 19T on a 15G map and Rica told you it would be OK? You can't be serious.

no i have an 18t, which as we know is much easier to control than the 19t's.

the only danger with the 18t is running to much boost as in std form they spool slower than the 15g. I was told that I have the fueling for 18psi so as long as i dont exceed that i will be ok.

the car also has good stage zero (new o2,sparks,cap and rotor + upgraded cooling systems) which will reduce the chance of any missing etc.

That's cool. Nice score on the turbo - 18Ts are pretty hard to find from what I've seen.

[bobcat]

Just to add,

here in the uk a guy running a 19t with a 15g map has just had his engine let go! he was running 13.x 1/4 miles which may have been down un controlled boost etc.

so yes slater, its always better to have turbo and map the same.
