That may drive the resistance of the SCP BUS higher than expected.

Flashing the car should not cause any problems though as the data rate will not be as high or near the demand.

Try taking a PID out of the log once and see if anything changes. Or start with 1 PID and work up until you find where the gauges go wonky.
I wasn't running the full amount of PID's but did have some extra running.
Glad to see this does happen,I was getting a little worried!

EggYolkedZX3 My car also does this during datalogging. Not quite like that Mustang but while cruising, the speedo and rpm gauges drop to zero for a second or two. I believe its normal and nothing to worry about.

Never had an issue uploading the custom tune from Tom.
Did the custom tune weeks ago.
This seemed like the dash was going through a series of self checks.
Things were intermittently coming on and shutting off while the datalog shows no interruption in data.

Just found a video that shows the exact same thing....

Nope.
I just talked with my friend Matt who does Dynotuning and says it was normal to see this while they tune as well.
Unsure if maybe one of My parameters I selected was responsible.....
