use command center in procede. BT cable / CAN tool for JB3. Who knows for JB4.

As I don't have access to the command center (no cruise control on my car ), which adaptations are specifically to be reset in the BT tool?

[TurboBimmer]

Just a fiendly bump. I never had to deal with misifires, but last week I got new plugs, coils and front o2 sensors in my car. Now the engine misfires around 6.800 rpm at WOT in third gear So I hope I will be able to solve this by resetting the adaptations, notably the ones related to the o2 sensors.

Can anyone confirm which values need to be reset via the BT tool?

Just do the command center 11 to 4 reset adaptations through the bt cable (just for reference to the right names and finish off with ecu reset

If you car just started misfiring after installing new plugs, coils and front o2 sensors, something was probably installed wrong. Or perhaps your software was updated as well. Either way, the first step is to update your harness. See if that alone fixes the issue. If not, go back to the dealers and have them reset all your adaptations since you don't have the cruise control stalk required to do it via procede. We will have an alternative for you cruise-control-less guys soon though. But the above mentioned steps should solve your issue. If not, the installed a bad plug/coil or forgot to screw a spark plug down all the way

This is probably the answer I have been waiting for. No more misfires at the track!

http://www.e90post.com/forums/showth...pdate+optional this is only for those who have catless dps? or its for those who have old dme soft like 2006/2007 year? if i have 2008 april built car do i need it to update? what about v5 does it comes ready and no need to mess with it?

I reset the adaptations and, if anything, the problem has gotten worse. The misfires (cyl. 5+6) appeared lower in the rpm range (around 4500rpm). As a last resort I will try the harness update and see if that helps.

I highly doubt my shop installed the plugs or coils wrongly. The car is notably faster than prior to the swap. Could the misfires be related in any way to the colder outer temps? This was the first time I drove the car with the procede in temps of -10 °C. Of course the engine was warmed up when I tried the WOT runs. Just trying to find some kind of solution...
