im running a cast iron big block...
The bin and xdf files seem match, OS 12208322 i can open the bin file and look at it, make mods but i haven't written it onto my pcm . I posted the files below if you can have a look and let me know...
Hi Guys, I'm changing to a cooler (160F) thermostat and would like to know what temperature range to set my cooling fans to? I figured that a good range would be 170F on and 155F off, with about 45...
