Bimmer Challenge Round 1 Prep Cont.


Downpipes are installed and we are ready for more data logging and revising of the tune. I decided to replace the spark plugs with NGK SILZKBR8D8S (97506) and change the oil with Ravenol 0w40 thanks to Motorsport Fluids.

(15.5k miles on the original plugs)









BM3 Flash Cont.


This time, we datalogged (granted street logs) for about 3 days straight. Tuner requested traction off 3rd gear 2500rpm WOT to 6500rpm, click 4th, repeat, and click 5th. 3rd gear was almost unusable, immediate wheel spin all the way to 4th. It was a game of keeping the car straight and not eating a curb. 4th would spin a bit, but begin to hook mid RPM range. We smoothened that out and the car felt great. Power was great, traction was manageable. I thought for sure we were golden this time.
