The ECU, located under the driver's seat. It's a Bosch unit, part number F00HM00027, Polaris number 4011370.
Nearly nothing is compatible..Jungleman, I'm still here and still working with this Ranger. I had a little medical problem with the family, but I'm now able to devote some time to fixing this little [email protected]
I've just picked up a compression tester, so I'll get on compression/leakdown tests ASAP. In the meantime...in case the ECU is the culprit, what other models of Polaris products used a similar or compatible ECU? I was hoping to simply swap ECUs with another 2006 Ranger, but alas, they are no other Rangers of that year in my area. I think simply swapping in a known good ECU would solve a lot of trouble shooting, wouldn't it?
