MSDS dropping cylinders

[wild E coyote]

I always thought this was a bad thing
for a motor but have seen where you
get to 8th in High and push minus on the steering and it detaches the MSDS
to not drop cylinders to eco mode
and the Trans. shifts normal., once the
truck is restarted the ECU goes back to
controlling the Trans.

MSDS is Material Safety Data Sheet.

Appreciate the information but this is common knowledge. It's actually called MDS though.

I installed a Pulsar XT module and permanently shut off start stop and MDS. It gives you control of several other functions too. The MPG loss is negligible and I believe it will keep the engine from problems down the road. .

i think its the root cause of all the lifter issues in Hemis

from what i have read recently, it's due to poor lubrication of the lifter and its surrounding components...
