The ultimate trawler

I read a report about converting a Detroit 4-53 to electronic controll. They used the injectors and ECM from a 4-71 DDEC. At the end of it they hadnt found a way to raise the rpm limit in the ECM. The 4-53 does well at 2800 rpm, the 4-71 ECM was limited to 2100.

If the 4-71 ECM isnt programmable you will just have to build your own ECM. Will take some knowledge of digital electronics and a scematic of the ECM. Its doable but is it worth the effort? Do you have a schematic of the ECM?

and when they do it is due to fuel issues which will disable your wing/second engine as well. .

As Ronald Reagan said, "here we go again."

Ok, go read the post "my cummins just stopped".

Wiring harness got wet. It could prevent my non ECM engine from starting as well, or any other non ECM diesel with an electric starter. There is no choice, any new diesel is going to be "electronic." For many years now TIER XYZ pretty well mandates electronic engines.

A lot of people wouldn't use radial tieres when they came out either.
