Ben Elwell Posted February 20, 2010 Share Posted February 20, 2010 Hello everyone, I was on here a couple years ago, but I have since lost my account information. So my uncle, and my boss, has a 1997ish Mack CH612, with a 9spd RoadRanger. After idling for an amount of time, the computer shuts down the engine, he is looking for a way to remove this shutdown "feature" and he is also looking to find out if there is a way to allow the injector pump to pump more fuel. He says he thinks that it will have to be done in the trucks computer but any advice on it would be appreciated. Thanks, Ben Quote Link to comment https://www.bigmacktrucks.com/topic/12727-more-power-for-ch612-and-other-computer-questions/ Share on other sites More sharing options...

Thanks, BenA dealer needs to hook up to it and disable the idle shutdown and make sure a parameters are set correctly in computer (tire size, gear ratio, governer setting to MIN/MAX, ect ect). If this was a fleet truck it might have a password for computer entry so the dealer might have to redownload ECM/computer, its very common. I would do this first before messing with the HP, turbo, injectors, ect.
