What DME/ECU Works?

[caliGreen]

I have a 87 325i.
i belive they come with a 153 dme

i normally see chips for sale but for a 173 dme

any "i" dme will fit? any benefit from diffrent dme?

[foofopps]

best bet is to actually take a look, you have to remove the panel in your glove box

Seriously no one wants to hear about all of the stuff you don't know or the HIDs your selling.

I lol'd. Sorry OP, have no clue. Keep searching and hope someone can answer your question.

I'm pretty sure it switched from motronic 1.1 to 1.3 (or something like that) after '87 so I'm not sure if the later DME will work. Since only one year (yours) of the m20b25 was made with earlier motronic it would make sense the 173 is for motronic 1.3 and you'd need to convert. However, this is all theory in my mind and may be (likely is) completely wrong.

Yeah you can swap dme`s. Search it. Lots on this forum about it

[jasonsnoddy]

ive had 3 different number dme's in my car, they have all been fine

[MR 325]

173 is said to be the best. You can swap one in with no problems. They go for about $50 shipped on the forum usually.

I have two 173's for sale for $50 shipped
PM me

Good to know. My bad. Never had an m20b25, and the b27 isn't worth two shits thinking about.

[unrlmth]

I have a spare 173 with a stock chip and also an e34 chip which im not sure what it will work in. let me know if you are interested.

[caliGreen]

cool now its eaiser to get a chip now. thanks guys . Great info

The 153, 173 and 525 ending ECU's are all swappable. However, the 153 ECU can't run a 173 chip. The 173, 381 and 525 ECU's all can run off of a 173 chip. Or you can use the WAR Chip and put it in ANY pre 1996 ecu:p
