2007 335i  [5.24]
Lightbulb Tried, tested, and true

It hit the 240 km/h marker. I tested this evening at the US 10th Mountain Division NY closed circuit training ground. Their CO were not happy when someone with the HSPD-12 secret clearance going hog wild on their training facilities specially when they found out I am a US citizen with an Ontario license plate. Too bad, their radar gun wasn't calibrated properly so I couldn't get an accurate reading. Well, no more mods on the bimmer until further notice. I am broke after nieces and nephews Christmas spending and the ECU flash; December expenditures are away out of control.

You said that before the mod you were regularily getting 10 km/Litre right?
YES
Was that on Sunoco 94?NO

Question, did you do the dyno run on Sunoco 94??NO

The European 325i doesn't make much more peak torque than the Canadian 323i... only some. I expected the European software to really make a bigger difference above 4,000 rpm which sounds like it is the case here?
YES
Another Question: How is the throttle response and engine driveability with the software?Life begins above 4000 rpm threshold

I think the only way to drastically improve the lower end of the rpm range on the 2.5 litre motor would be to get Supersprint Headers or to delete the catalytic converters (or get higher flow ones) in the exhaust manifold.

Going with headers would surely throw Check Engine Lights unless there is software to compensate or if O2 simms are installed.

Getting higher flow exhaust manifold (that is to say, higher flow cats in there) would help low end grunt also and you wouldn't have to worry about Check Engine Lights, I wouldn't think. Turner Motorsports sells higher flow exhaust manifolds for the US 325i and I would imagine that those would fit a 323i.

So over all you like your "325i" then?
Shipping ECU to the US: $190
Flashing ECU: $769
Shipping back ECU to Canada: $120
Removing ECU and installing them back: tears and sweats
Hassle with the US Customs: tears and sweats
Upgrading Canadian 323i to Euro/Mexican/Asian 325i: PRICELESS
For everything else, there is a mastercard, GST, and PST
