it is my understanding, from what i have read online at various DSM sites, that cars with automatic trannies have both an ECU and a TCU. whereas, manuals have only an ECU.
it is also my understanding that the ECU and TCU do not communicate with each other.
therefore, would there be any problem with using an ECU from an 89 galant SOHC manual for my 89 galant SOHC automatic?
reason i'm asking is because i recently found one in a junk yard for $60, and i thought i'd give it a try. i have yet to completely hook it up, since i need to get a new battery, too, but i thought i would ask the experts before attempting it.
if it doesn't work, my next step is to try to replace the capacitors on my existing ECU. and, if all else fails, i guess i'll be looking for a nice ole' beater car, lol.
the main thing i'm worried about it my car blowing up on me, lol. otherwise, as long as i can get it running for another few months, i'll be a happy man. any suggestions/comments are welcome and greatly appreciated.
