Efilive communication issue with dyno (powerdyne) software

[Dmaxink]

Has anyone ever had a issue with the scantool not connecting when the dyno is connected? This also effects the lockup controls on the dyno. The scantool will not connect or log when the powerdyne software is engaged...any takers?

You can't run two scantools on the vehicle at once.
Or, is the Powerdyne software running via V2?

Cheers,
Ross

Photo tach is the only way to go if you want to log while on the rollers. We have a spare five speed Allison TCM tuned for fourth gear only with TC lockup in TH for dyno tuning. The six speeds usually hold in manual mode.
