Question about M274 engine differences
Hello mates, how are you? I hope you are all fine.
I was wondering if someone knows the actual hardware differences of the M274 engine in the 135kw compared to the 155kw versions... or is it all a software thing?
About the transmission, is it me? Or the transmission seems to have a dual clutch and not a torque converter... when accelerating in 2nd gear and low revs, it just feels as if a clutch was engaging.
Thank you all!
Joaquín

I too have read power is ecu/mapping but can't be 100% on that. if I keep mine it's getting a remap.
gearbox is old school slushbox (both 7g and 9g) with a lockup clutch (hence you hear lots of people moan like me about jerky engagement).
