MDS On/Off Switch

[magnuman]

Now that I have done my MDS "On" Indicator light mod.,
MDS "ON" Indicator Light
and my WOT fuel mixture control mod.,
Mixture Control at Wide Open Throttle (WOT)?
I am thinking of hooking up an MDS on/off switch so I can get better control over MDS operation. I am still researching the hook-up, especially the way it may afftect the PCM, if at all. Anyone with ideas, pros/cons, potential problems, etc. on how to implement this mod., please put your two cents worth in. Will it even work??

magnuman you are the man and if you can disable the MDS, then that will be the best performance mod for our cars period.
Thanks man and keep up the good work in all HEMI forums.

Everything I have read indicates 1) MDS only operates when operating the car in a manner full power is not needed and 2) when power demands exceed what is available with MDS activated, the system deactivates in such a short time (a very small fraction of one second) that you can't tell it was every activated.

I just can't visualize how deactivating MDS would help performance.

It's called wild, adult-choice, freedom from control, exhilarating swim naked with the sharks FUN

No point in being alive without it:

I think you missed my point. The full power of the Hemi is available whenever you want it. Deactivating MDS would give you no additional performance.

Exactly. The fraction of a second it takes to 'kick back in all eight' would be more than overshadowed by tranny delay, etc. Wouldn't even notice it.

I apoligise you are correct I am still jet-lagged after a 12 hour transatlantic + trans-Canadian flight :o

Watch out for more goofy posts - more goofy than usual that is

Does it work at 80 mph?

I'm also interested in disabling the MDS but for another reason. Maybe, just maybe, I'm being totally paranoid but I wonder what effects MDS will have long term?

My thinking is as follows: 4 cylinders are always in use while the other 4 are not always in use. So, 4 cylinders will always have more wear and tear than the other 4. I'm just wondering at what point will half of my engine will be 'worn out' while the other half is still OK.
