Lets try this one more time for those following along at home. Get your popcorn ready!
My post:
Just wanted to share this, pulled the trigger and had my ECU tuned to delete the MDS from functioning. Super simple, mailed my PCM out and he mailed it back with no more MDS!!! The guy said if sending in my current PCM wasn't an option, that sourcing a used one could work too.
Your post:
I don't think it's all that wise to disable the mds,unless you do it properly,and that's pull the MDS solenoids and replace them with the factory MDS block-off plugs,then swap lifters and cam to a non-mds set-up.Throw in the fact i don't think MDS is the issue with lifter failure,as both non-mds and mds lifters have been known to give trouble. If MDS was an actual issue,the 6 speed manual transmission 5.7 and 6.4 Challengers would never have lifter issues,and they have just as many lifter issues as the automatic transmission engines with mds have,if not more.If you factor in the amount of non-mds manual transmission Challengers they built,there's a pile of them having cam/lifter issues in comparision to the amount of MDS engines they've built.
There's quite a few outfits who'll delete the MDS in your factory PCM ,MMX has been offering that service for quite awhile now,and i know lots of tuner outfits on the Hi-Po facebook pages also offer the same service
My post:
Why is that not wise? If the truck disables it in manual mode what makes you feel that it’s not safe to run that way all the time? You think Dodge made it to intentionally fail if driven like that?
Also, if the concern is lifter failure, and we aren’t sure whether the non-MDS setup is any better (and if trucks without MDS disabled are having issues as well)… then you might as well disable with software and run it. Then in the event they fail, feel free to replace with the non-MDS hardware.
Replacing before hand makes no sense.
My post later:
As was mentioned by others in this thread, there are certainly benefits to changing some parts/parameters on any given engine. For instance, higher idle speed would make sense to me as an attempt to lubricate better. Any of those things MIGHT help SOME people SOME OF the time.
The issue I have is that you say to delete MDS the right way someone should disable in a tune AND THEN ALSO replace all their hardware. But, if we know that non MDS engines have lifter and cam issues just like the MDS engines, there is ABSOLUTELY NO REASON to replace hardware that isn't broken. If someone was concerned and trying to prevent the tick then by all means do whatever other mods tickle your fancy... but for you to tell someone the "right" way to do something because that's what you "feel" like (and leave out the facts) that is just plain wrong.
I have been saying all along you are incorrect that all the hardware needs to be replaced. This post was not a discussion on tips and tricks to avoid MDS failure. You have a real tough time coloring inside the lines.
