just bought the standard excellerator from ppe... just need to know do you really have to pull all the fuses before you plug it in an start programming? also any other important info or suggestions on programming would help me out. thanks
Also any after market stuff like a radio turn them off, unplug or pull fuse. knowing worst than a device sending garage on the data bus during a write.
Yup. I pull the fuses, sit in the truck, turn the headights off, roll windows up, radio off etc and then do your programming. No need to be goofing with anything while its doing its thing, ECMs and Tuners are expensive! :thumb:
