I recently purchased a EFILive from Dirty Diesel Customs and was wondering if anyone knows which fuses to pull to flash. There is no TBC battery or TBC ignition or info fuses. I don't want to screw up the ECU considering it's my service truck. Thanks

I'd contact dirty diesel customs to see if they have the exact info you need.

Unfortunately they don't deal with topkick vehicles. Different fuse boxes. I've already talked to them.

Has anyone else flashed a c5500? I'm sure the RV guys has. All I need is which fuses to pull for the flash.

It would be time consuming but you could pull every fuse but the ones for the ECM and give that try?

Why do you think you have to pull any fuses? The only time I would do that is if there was no communication when you try to flash.

Ok thanks, it says in the instructions to remove. I'll just hook up a battery charger and send it.

Well, that primarily applies to the pickups.. the Info fuse I believe is related to rear seat entertainment and maybe a few other non essential systems that could interfere with the flash process... That being said, the very first time I flashed anything on my LLY, when it was still a LLY, I pulled fuses because I was paranoid... Future flashing with EFILive, I didn't pull squat and never had an issue.... YMMV.....
