Turner Conforti chip for m20b25

[CharlieVu]

Ecu?

which ECU? and does this work with Automatic transimissions with sport mode?

[Shu]

Assuming the box is correct for the ECU, this is a chip for a manual transmission with a 525 ECU.

[cheffy30]

being ignorant here, do they make chips for the autos?

[ForcedFirebird]

Auto and manual ECU's are interchangeable. The 525 is the one with a speed limiter and came in the auto.

This chip will work in any Motronic 1.3 (173, 525, 380, etc any with a single circuit board inside).

Can this be used in a 153 ECU or 173 only?

No, the 153 is Motronic 1.1 and came in the early 325i. The 153 variants have 2 circuit boars inside and all those ECU's can interchange chips.

[Misinformed Youth]

This chip worked on 173 ecu on my manual 1990 325is.

Chip is SOLD thanks guys
