Sharing the same hardware than the e46, the m48 has been developped for high-speed naturally inducted engines up to 8 cylinders.

 

The RPM and load sites have been adapted as well as the auxiliary functions. The m48 is perfect for installation on motorcycle engines or on engine that runs over 9000 rpm.

 

Using the same test and manufacturing standards than the e46, this ECU is sold in complete kit and is delivered in an aluminium machined housing.

 

Public price (french VAT 19.6% not included):

- ECU alone: 585 € 

- Kit including ECU, half-finished wiring-loom, water and air temperature sensors, computer cable, CD with software and handbooks: 668 €
