Default iat fluctuations - 05-19-2017, 02:51 PM

drove my car for the first time in about 4 days noticed that my iat temps were fluctuating all over the place. snag are few logs that I could take. didn't want to get on it to hard for to long. can someone maybe take a look and see if they notice anything. currently waiting for the engine to cool before I start digging in. also I noticed that the rpm and Speedo did a sweeping motion when I was driving. people were saying it's the jb4 resetting itself? couldn't find a link with a definite answer or solution, anyone experience this? thanks

As far as I know the sweep is a feature, look at the map guide that tells you which settings do what.

I know you can get the gauges to sweep on start up but this was in the middle of driving.

Sounds like you may have a power connection issue with the JB4.
