You could easily remove the torque sensor but why would you want to do such an stupied thing like that? Thats there to save your transmision from falling into pieces. ESS Tuning (I think Technik as well) can program your trans. ECU/DME to accept X amount of torque without going into "limp mode". So by removign the torque sensor your really

well fellas, I sold my car about 6 months ago, and I just got word from the guy I sold it to that the tranny went on it. I had 325ci step with the following mods: AA supercharger, technik headers, technik cams, RE DMS exhaust. I personally never had trouble with the tranny, not once did it go into limp mode, but I guess over time the tranny was starting to go. So for everyone in a 325, I guess that is pretty much the limit of the trans. I am not sure how much power that car was putting out, but I guess it was close to that 300 limit. just a heads up

So i was bored as usual and surfing the web and saw that the new GTI has better performance stats on their auto than the manual. Can someone explain this one? I think it was almost .3 seconds difference to 60

The corvette is faster in auto for striaght line too, at least the C5's were. The reason is that the auto is set up differently than on the BMW's, harder shifts, a different torque converter, and the clutch packs are tightened up more. This means that the tranny shifts faster than a manual and holds the power where the tranny in a BMW is set too smoothly and wastes power after a shift to keep it smooth.

My Ride: 2001 Jet Black 330Ci
Quick little update here...I have had the S/C on for a few months - 330Ci with ASA S/C @6.5 PSI, steptronic with 330 crank HP. I have only put on about 5,000 miles with it for various reasons (car in shop, I have a 2nd car, short commute to work, etc.), but its still going. I have attended several autoxes now, and have been driving her very hard...redlining the $hit out of it.

I have had 1 tranny problem so far - occassionally when cruising in 5th gear, the tranny will downshift to 4th all of a sudden and I can't upshift until I get off the gas for a moment and then shift back up. I spoke to a BMW mechanic, who gave my tranny error data to BMW's ZF transmission specialist. He said it is not slipping...nothing wrong with the transmission - that he believes its a software issue. Reverse, and 1st through 4th are no problem. This problem hasn't happened since my shop reset the tranny adaptions recently.

I got myself a video camera finally, and I need to get a video capture card so I can post some videos for you guys.

There is one way which I figured out how to make my/E46 trans. shift harder. Funny to say but it was mistakinly discovered. I have an Apex'i S-AFC 2 on the car and by having that, I was able to adjust the A/F ratios to my needs (running lean) . Also, to the ones which are unaware. The Auto trans. reads off the MAF to select a specific shift point during WOT or econ. driving. How this was done is by rapidly changing the A/F ratio with the S-AFC during idle and setting it back to stock(I was testing to see if the unit was installed correctly). The gear warning icon appeared along the clusters. The trans. ECU/DME thought something was wrong due to low RPM and rapid A/F ratio changes which set off the trans warning light. By all this, the trans. started shifting extremely hard. Even at low RPM's. Also, during shifts the car would leap forward. I didn't know if this was healty/safe for the trans so I reset the trans ECU/DME. To do this you turn off the car and set the key in the second position and place the shifter in nutral. Roll the car forward and back for about 5-4 ft. each way and the trans. warning light will disappear. A lot of trial and error to figure this out but once again. I don't know if this is safe/health for the car. I will do some more research to find out if this "self mod" is efficient.

That's what happened to my 1990 735i right before the tranny blew. This was with 3rd and 4th gear though since it doesn't have 5th. It's also happening to my friends stock 1995 325is and I can tell the tranny is starting to go, even though there is hardly slippage.

Oshin all you did was put the transmission in 'safe mode' this is what the ecu/dme does to prevent further damage to the transmission. Did you try putting it in sport manual? after 1st or 2nd gear it will shift it self back to automatic and it will remain in 3rd gear which is the mid ratio "safest gear" I wouldn't recommend messing with it, that is why you can buy tuned chips for your tranny so it shifts @ higher rpms...

What he is describing is not limp mode. The car goes into limp mode (tranny wise) when the explanation point is on the cluster where it indicates the gear selection.

When it hits that exclamation point, you better be very careful. If it gets any worse, the car will not unlock the gear unless you restart the car. And if it gets any worse, carry an OBD-II reader because the tranny will throw a SES light that locks the tranny. When you get the random downshifting and locking is when you should be careful. Ask me how I know?

Anybody know the limits of an XI with F/I? I figured i'd ask since we seem to be on the general topic.

As you can see in my garage I have reached the limit and now my ZF transmission started slipping in 2/3 and 3/4 shifts thus going into limp mode and turning off the car and restarting it. The answer is to get an upgrade from IPT - you will see several threads here about upgrading and IPT. IPT said to do a complete upgrade of the torque converter, valvebody and transmission drive components (see their website) to withstand what I have in my car. Buckhead Import Performance (does a lot of FI installations) agrees.
Now waiting on back-ordered BMW parts to finish upgrade.
