SIP speedometer 2.0 on SIP Vape DC : RPM does'nt works

Hi Everydody.

I migrated my PX 2011 to SIP Vape ignition DC version then I just install the SIP 2.0 Speedometer. Everything but the RPM is working ... and it was for the RPM function I bought it 😢

Am I facing an unexpected - and untested - situation by SIP or someone has some tricks for this exotic configuration ?

Thanks and take care of you.
