M44 rev limit
 

Hello guys, came from BF due to a member's recommendation.
I drive Z3 1.9 (M44B19) which has Bosch(?) M5.2 DME. It's European model so OBDI.

I'm trying to raise rev limit to 6900~7,000 rpm for more room on downshifts.

What do you guys use to read the current map?

If aftermarket plug and play modules are available I am also interested in those.

Thank you!
