Depends on what you're trying to override. You can't simply just bypass the ECM, since the engine won't function without it, but some features can be overridden or bypassed. For example, speed governors... but I won't tell you how for that one. Idle shutdown can be programmed to be overridden a number of ways or not be overridden at all.
First, you have to change the ECM settings.
Adjust the parameters in the engine ECM. This will require the engine ECM software (DDEC for Detroit or Insite for Cummins) and a Diagnostic Link Connector (such as Cummins Inline 6 or NexIQ).
No
Go to a dealership or certified maintenance shop, and have them change the ECM controls.
The engine computer is mounted on the driver side of the engine block.
It's programmed into the ECM. You'd have to take it to a shop which has the software for it. If you have a MaxxForce engine, your only option is an International dealership. If it's a Cummins, any Cummins certified HD shop will have the Insite software. If it's someone else's truck, they'll probably have an ECM password you'll need in order to access the ECM.
The governor is simply line of code programmed into the engine ECM. A truck shop with the appropriate software for the engine (e.g., Insite for Cummins, DT for Caterpillar, etc.) can hook up to it and remove that parameter, provided they have the ECM password.
The engine computer is also the regulator, it is behind the battery. Not on the 1991 Dodge Cummins, the voltage regulator is located on the firewall. On the 1991 gas burner, it is in the ECM.
in the cooling plate for the ecm.
Gear down protection... it's a feature programmed into the ECM to prevent excess RPMs, which, in turn, protects the engine.
No. The higher HP Cummins require a different ECM. The increased HP engine was programed differently and was usually a *Celect Plus* . Also be aware that the ECM plug has a different wiring cofiguration and will not simply plug inton your OEM wiring harness.
