I had the 392 in my 2012 SRT grand Cherokee and purchased the Diablo Tuner from Trinity just for the sole purpose of deactivating this feature. I can not get my head around a 8 cyl. Engine running on 4 cyl. Anyway it worked perfectly. I saw consistently 18-19 mpg. I still have this unit as I put everything back to stock when I sold the SRT. Probably will not work with the latest software but maybe Trinity might be able to reflash the unit to operate with the newer Jeep. You are welcome to it for free if you would like to try it. I have no use for it and can’t just throw it in the trash. Send PM and it is yours.
MDS itself is not the issue. The issue is the damage that the MDS can potentially lead to although i don’t think MDS has been directly linked to the damage. It’s more anecdotal, I believe.
Where is the 4 cylinder light? Never seen it. I looked in the manual and in the performance supplement, which does mention it, but not what it looks like or where it is.
The 4cyl indicator is on the MPG screen.
