Could a Super Chips kill my PCM?

Hello,

i just joined the forum.

i bought my 96 from a family friend, (which has 136,000 miles as of now,) and it came with exhaust mods, cold air intake, and an inter-cooler. Plus a Super chips tuner.

i tried the tuner in all 4 settings. Stock, safe tow and the two other performance settings.

not desiring anymore power from the truck i tried them all to find the best fuel mileage. which was Safe Tow mod.

Well after 5 years and about 20,000 miles, with no problems running it in safe tow mod, one day the engine quick. no start.

ended up being the PCM went out.

so i asked the service writers at the stealership which there were two of them that delt with me. and one said that the tuner can make the PCM go bad. the other said it can not.

so i went to the internet to look for answers and have found conflicting answers as well.



SO, now i will ask the Powerstroke forum.

Can a Superchip tuner, (Set at Safe Tow,) make a PCM go bad prematurely?

If you've been running it for the past 5 years and no issues then I highly doubt it. Could be uneducated mechanic trying to put blame somewhere as he probably doesn't know his way around a 7.3 very well. The PCM may not have ever went out and they put one in it, didn't tell you it was probably a fuse and stuck you with the bill. Did they give you the old one back?

I figured so. No way to swap it back to see if it really was the issue. Darn. Service writers are good for that, sometimes they can lie just to cover their mistakes. Not all do that though. Some dealers really can be good. Just not usually.

they said it had low fuel pressure. so did the shop before. but the other stealership wanted to change out parts until it worked. starting with the ICP and IPR for $1,500. then if it didn't work after that the HPOP for $2,500. then if it didn't work they wanted to start changing injectors.

so i towed it to this stealership and they diagnosed it as low fuel pressure as well and thought a possible PCM.

the service record says:

monitored EEC PIDS, found ICP pressure does not reach 180PSI, load tested IPR circuits from PCM to IPR valve. found wires and pins test ok, installed known good IPR valve and checked code to clear,found code still triggers, suspect PCM is not commanding IPR, recommend replacing PCM with aftermarket rebuilt unit, test drive and verified operation of PCM.



i have no reason to doubt they did the work, but i would like to figure out if whether or not i could be left standing because of using this Superchips tuner. i go way out in the woods with this truck and it would be a looooong walk back if she broke down on me there.

Low fuel pressure

Change fuel filter. Then check pump at idle pre filter. Check fuel pressure regulator. Then check pickup screen in the tank.

Wow $1500 for ICP and IPR change.

Dealer price $200 ipr takes 1/2 hr
$125 ICP takes 10min to change.

ya, that's why i didn't pay them to do it. if all they are going to do is change parts, i can do that. i wanted an educated diagnosis done.

that is why i towed it to another ford dealer.

i had already changed the filter, and CPS at home. it is a bit of a long story.

i pulled codes and came up with three different ones. none of which i could tell exactly why i had a no start.


HowEver.
the main reason i posted though was to get more folks opinions on the probability of the Superchips Tuner harming my PCM or not.

anyone else ever hear of this?
