First of all this is for my uncle who has no internet. He's got a ddec 2 and he's been told there's an aftermarket map sensor that will lie to the ecm, and trick it into giving it more fuel, but can't seem to find one. Does anyone have any idea about this? Or anything else to boost HP/TQ. I don't think he's real worried about economy.. Thanks for your help!

 

I had a post on the series 60 in this area ,ddec 2 is an old series engine small injectors so it will not make a whole lot of power but they are great on fuel I have a ddec 2 and a ddec3 and the 2 beats the 3 in fuel mileage but the 3 has alot more power tried it yesterday with a large load of rock (little overweight 100,000lbs on a tandem trailer )

 

 

not much you can do to a ddec2 due to them only have crusie control, no ambiant air temp sensor, coolant sensor, oil temp and pressure and engine shut down features
