whats the odds pcm programming

If say you send your pcm in for a tune or security removal which is popular. How easy would it be for them to accidently fry it?

Very tough. Its possible to get a bad download but frying it requires hooking something up wrong and when you've done over 1000 of them with the same cable I would say its impossible to fry one.

+2 on reds comment !!!!

On vehicle it's easy with low battery voltage, etc. but pro tuners rarely have trouble I'm sure. They don't usually have to worry about slow TIS connections or crappy vehicle content when they're tuning on the bench.

Why do you ask?

Sounds like a loaded question....LOL

It is.


I just need a little group agreement that while its not likely, its is possible something can be accidently done wrong during the tuning process, either frying the pcm or rendering it temporarily useless. Then Ill explain. :)

There is a higher likelyhood for it to get fried during installation than during programming. Plugging and unplugging voltage, miswiring, dead batteries, short circuits,...

So your saying there is a chance...however small...something could go haywire during programming, be it human error vs physical connection?

I dont disagree with you.

If I were a gambling man I would not take that bet.

There's always a chance for failure but I agree with Greg it's slim. What's on your mind?

I'm not sure if we tuned your pcm, but I'll answer anyway.
To actually fry a pcm, is very unlikely. Most tuners have a harness that is setup and stays that way. I guess you'd have to physically swap the neg and pos cable and apply power.
But, the power supply we use, doesn't allow that. It will not keep power on if it detects even the slightest short.
As far as accidents, that's always possible, but I've personally seen pcms unplugged during programming, power dropped, shorted out, low battery, you name it, and they always work in the end.
I have seen a calibration not take 100%, but there's no way to know if it did or didn't, because you can't plug in and test every function of a pcm before it ships.
When doing so many, all you can do is rely on the software, and like all companies, most applications have bugs.

To answer your question specifically, something like vats, it's unlikely.

hope this helps.
