Can a DDEC IV ECM be used on a gk60?
If you have an ECM failure and get a replacement from Freightliner or Detroit they will set you up with a DDEC IV with a special program calibrated specifically for older GK60 Series 60 sensors, injectors and camshafts.
Are there any problems with the series 60 engine?
We’ve briefly discussed some of these problems in our Series 60 spotlight, but we’ll dive into them a bit more fully here. It Still Runs also mentions a few of these issues. Cold starts, aptly named for starting your engine in cold temperatures, have given Series 60 engines trouble. They can lose their prime and not start properly.
Are there any problems with the Detroit Series 60?
This issue did not affect all pre-2002 Series 60 engines, but it was a problem that occurred and could cause catastrophic engine failure. As with most engines, it’s a good idea to keep an eye on your cooling system. Overheating is the cause of many major issues with diesel engines, so maintaining this system can help with many preventable issues.
What happens when a DDEC ECM is replaced?
A very common oversight occurs when DDEC ECMs are replaced and inexperienced or otherwise unaware DDEC programmers configure or uprate that DDEC incorrectly. When Detroit programs are copied from one truck to another sensor correction factors are also copied from one truck to another. This sensor-program mismatch can lead to all sorts of issues.
What should the coolant temp be on a DDEC IV?
After a while you might think something is wrong with your engine or your coolant system. The reality is when your DDEC IV reads the signal from your old DDEC III coolant temp sensor it reads 200 degrees but if your old DDEC III was reading that same signal it would read 224 degrees.
What causes engine to overheat when running DDEC?
One big problem involves the coolant temperature and the engine fan. Running a DDEC with the wrong temperature sensor calibration can cause the engine fan clutch to engage before the engine is fully warmed up causing a loss of performance and fuel mileage or fail to engage when temperatures go too high causing the engine to overheat.
