Hey last niteit was cold I was on 80 heading west when a 750il want's to play, Anyway I drop it into 3rd and take off with full throttle and and I notice my car is bucking like hell. I let off easy on the gas and it stop and @ the time I think I spike at 14 lbs of boost can it be my fuel cut is reached it's limit? Or is it my 3k hesise? Or my ingition breaking up? Also I ahve alot extra grounds, I never get on the car whenever it's like that cold, At this time of the year we usually get like snow already, so I never drove it in this type of weather before so I am not to sure what it is? Also I was already cruising at 80 mph when I drop it into 3rd and take off. khris

 

3rd gear 80 MPH is like 5500rpm i think.......i'd say fuel cut....

 

since it's cold, you may be boost spiking. What ECU are you running?

 

Yeah,



I had a funny bucking type thing happen in every gear as I accelerated the other night. Down at the drags.



T'was the boost cut- damm factory computer (soon to be replaced).

 

Well I am running M2 stage 3. I am thinking of buying a power fc is it worth getting the power fc? Khris

 

It's always worth getting the PowerFC! I have the PMS piggyback, and it has a built in boost controller that pretends to work.. I realized I never removed the wastegate line pill, maybe that's the source of the overboosting problem for you and I..

 

I did yank the pill, I had always had the mbc it work fine until the extreme cold weather kick's in.
