6-pot ecu's

[magpie]

is it possible to use a motronic 1.3 320i ecu with a 325i super chip and use this in a 325i ?

[Brianmoooore]

Short answer - yes.

Short answer - yes.

thought so

Is they any downsides to this set up, from using a 325 ecu

[tha881]

This is a 380 (325i) and 172 (320i) ecu, although not sure which is which if you know what I mean

[Brianmoooore]

Only downside is that it might confuse some future mechanic when he finds the wrong ECU fitted.

All later six-pot Motronic 1.3 ECUs (172/173/179/380/381) are all essentially the same, aside from the program on the EPROM chip and the label.

Only significant difference is the later 380/381 has extra diodes for the idle control circuit (which are prone to blowing).
