Hello everyone :)
I'm a new member to this site/forum, and I must say I pretty much like it :bow:
I currently own two E30s, a 2.0L and a 2.5L. The 2.5L has just been purchased, in order to replace the 2.0L because I had major problems after the engine swap I did ( it was originally a 316 and I put the 2.0L engine in it ) and I'm in the process of bringing every last piece of the car to my liking... as the car's general shape and condition was spectacular, not to mention the price I paid for it. ( damn cheap ).
I wanted to ask something about the ECUs. On the 2.0L one, I have a 172 Motronic 1.3 ECU, with the stock chip and the rev limit up to 6500 rpm. ( i also have another chip that raises the rev limit to 6900 rpm ).
Today, I felt like placing the stock chip of the 2.0L ECU to the 2.5L ECU. ( Currently, on the -to be sold ASAP- 2.0L car I have the chip that goes up to 6900 ). But when I saw the 325's ECU number I hesitated for a while. It wasn't a 172 or 173 ( I thought those were the only ones... ) and I thought that the chip wouldn't work. And all that fuss because my 325's rev limit is 6100 rpm :(
The 325's ECU code is 261200380. I don't know any further information about it as I haven't checked the ECU with the appropriate device that does all the scanning for the Motronic version and the car's problems and all that.
I wanted to ask if I could just swap the ECUs right away ( if such an action is something I should do in order to take advantage of the better ECU between the two ) because I am taking everything that's worth from the 2.0L E30 and putting it to the 325 and then selling the 320. Which one is better and for which car?
Would there be any problem with gas ignition, fueling and all that? Are the ECUs differently programmed for the 320 and the 325? ( I suppose they are, right? )
I wouldn't want to do something like that without knowing 10000% if it's right or not, hence I'm asking if someone knew anything.
Thanks in advance for any help :)
P.S. Awesome place for our E30s and for bimmers in general, great work :up:

is that you should NOT do the ECU swap.
