97 7.3 pcm/reflash

[dean148802]

Hey all I am a new member today. I purchased a 97 f-250 about a month ago and i love it. I took it to a local mechanic to run the codes to see if anything was popping up. It gave me a 605 code which is a pcm. He tried to reflash it but it wouldn't which he was saying was because it was bad it wouldn't reflash. I currently have a alarm system in it that I think prevents it from running the reflash/ tests correctly. Even with the keys in the ignition it will make you pull them out, press the unlock button and continue on from there. Should I have him disconnect the alarm and have him check again before i buy a new pcm? Also if I end up buying a pcm are there any aftermarket or would it be better to get a reburned one?

prolly nothing wrong with the pcm it more than likely has a performance tune installed causing the p0605 (aftermarket equipment) code. remove the 3 13mm nuts from the ebrake pedal assm. and this will allow you to see the back of the pcm inwhich it may have a chip plugged into it. if you decide to remove it make sure the keys are out of the ignition. if no chip is present then it must have reflash tune installed.

It had a banks ottomind chip in it. We removed it so it could be reflashed but it would not reflash. I decided to leave it out after learning that i need to get a pcm. I would love to get a new chip like the 8 point you recommended but if my pcm is actually bad would it ruin the chip?
