Could they tell if ford can plug into the comp to see what speed and rpm the engine was running at if it blew up??

If you change the whole comp in the truck, can anyone tell that its not the org comp,,

thanks

 

well its kind of hard to read codes after you disconnect the battery then re-connect it

no you can't tell if its the org pcm, as long as it is programmed for your key pats and year code

 

so if you change the whole comp they shouldnt know and what about if you left the comp and changed the chip,,,

what does what

like chip vs comp

 

don't know what you are trying to ask sorry

 

They will always be able to tell you had a chip if you do not substitute the ECU.

If you even want to substitute the ECU you need a friend that will re-PATS your new ECU for your key-id otherwise the new computer will be rejected.

soft codes can be erased by disconnecting battery

Hard codes can't!

 

Our computers do not black box run data like GM and others are doing for tattle tales now. I expect it soon in the future.

 

You could always buy an extra ECU that isnt programmed for your PATS and chip that.....then if you blow it up just switch the original ECU back in before service and noone would ever know

Except for your karma.

Shirking responsiblity, its as American as Apple Pie!

 

Ok but how can they tell that you had a diff chip in the comp if you put the stock one back in and make it look legit,,
