So a friend of mine has asked if I can mod something for him, I'm not sure if it's easy, hard or impossible. He has a jet engine for a model jet, and it has a 12F629 on the rotation sensor, and a 18F26-something on the controller, I'll check these and update when I get it home and open it. The modification he needs is small, on starting it kicks up to a high speed of around 110k rpm, he had customized his jet engine (very skilled in machines, not in electronics) and needs the controller to only start-boost to 50k rpm. I have a Microchip ICD 2, and an Easy Pic Fusion v7 which has their version of the ICD built in. The boards both have a RJ12 which appears to be wired to program the chips. They don't seem to be read protected. I've never pulled code from a chip, I know this will need to be disassembled, and a little online research shows that I will probably need to replace the precompiler settings. I wouldn't be surprised if this is one of those tasks that seems small and is actually huge and not worth the effort, but I thought I'd seek advice here before saying I can't do it.
