Strange spike after "running" comes on

[NitroX5]

Firmware 1.1.79 (still connection problem, no chance to downgrate for a released version... however I have found some solutions)

FIRST startup on 5cyl engine.
Under cranking everything looks fine(pulsewith, 14° spark) but as soon as the RPM left the crank period and get to running state, two values going crasy.
VE goes double and spark angle drops to 0.5°  Because of this RPM drops back into cranking mode again. I have checked all setting what could related to this issue, but no success. Is this caused by firmware?

After buying a proper FTDI USB-Serial cable, connenction problems gone completly.
Now, with 1.1.74. firmware and inspection over settings, those spikes are also disapperaed.
