ECU Black-out during logging on the dyno

[Bigggy]

This week-end I had a dyno day with some buddys and on the first run of my car, my laptop was connected to the SCT X3 with Live link and at around 4k rpm the gauges went crazy and I lost communication with the ECU. At that moment the car kept going and the gauges came back at 6.2k rpm just to finish the run.

I've disconnected everything and it did not happen on the 2 other runs.

Anyone ever seen that?

Other strange thing, the A/F of the shop was going crazy rich at at 5k rpm, even if my AEM was at 11.0 at all time (I know its too rich).

I had the same issue with my xcal3 and many others have also. I had to get rid of it and get an xcal2. I found someone in the market to do a straight up trade.

The gauge thing is common when datalogging.

Thanks guys! I did some logging last friday and it was fine, just weird that it started on the dyno. I will do some more logging this week, so I'll see if it do that again.
