Running rougher while connected?

Post by Map63Vette »

So I think this might all be in my head, but I swear my engine seems to run different when I have my tablet with MSDroid connected vs. when I run without it. I have a little cheapo 7" Chinese tablet I'm using as a digital dash (and speedo at the moment) that I have mounted under the dash in my setup (a 5.7 Hemi with MSD ignition control and fuel only MS2Extra). When I'm cruising down the highway without the tablet, it seems like the engine runs silky smooth. However, when I do the same drive with the tablet connected it seems like it just doesn't quite run the same. I realize that it would probably take some amount of processing cycles to provide data to the tablet from the MS, but surely not enough to compromise the way it runs right? I have a bluetooth dongle constantly attached to the MS for what it's worth. Has anyone else ever experienced this same phenomenon?

Running Ms2Extra too, but fuel and ignition. Also connected via Bluetooth. Didn't notice any difference between logging using TS/MsDroid/no log so far.

I have occasionally seen this happen if there are grounding issues with the device connected.
