I just download a free version of multiecuscan, and connect it with an ELM V 1.5 to my Delta III 2.0 16V 165cv DPF.
Connection and dialog seem OK, but data are not stable. For instance, the rpm values fluctuated from 48 to 125 to 520 to 145, several times by second.
Same problem with the other parameters.
Do you know the cause ?
Is that due a non modified ELM 327 ?
Is ELM 327 V 1.5 OK ?
Does my car need the ful version of the software ?
Thanks in advance for yours replies .
