Before I started having the cold weather ECU issue, the ECU was working fine (had the jeep over a year). As I said, the number of the ECU in this Wrangler is 56028828 which I was told was for an automatic 4Cyl 95 Wrangler. According to the Parts Store, the one listed for a 95 4Cyl Manual one is actually supposed to be 56028828.
In a number of postings and searches I read that the 92 to 95 Wrangler ECUs are interchangeable (i.e. http://www.jeepforum.com/forum/f12/someone-school-me-ecu-ecm-pcms-real-quick-331965/
)....as long as I stick with the 4 Cyl Manual version (despite the fact that my Manual Jeep was using an Automatic version of the ECU).
With other web searches I found this list of ECU numbers...
However, it doesn't break the list down by Number of Cyl or Automatic/Manual. Oddly enough, neither my current, nor the one the parts store said I should be using is in that list.
So, what I'm trying to do is create a comprehensive list that I, and others after me, can refer to for situations where the ECU needs to be replaced....making it easier to get one on eBay or such.
