Ok i finally got my first Vi-PEC in to tune last week and put simply it went extremely well... for two reasons.
First reason is the installation and setup time is around the same as a POWERFC D-JETRO... plug the unit in and fit the intake temp sensor to the manifold or piping whatever your fancy.
Secondly and i suppose most importantly for me was the software was instantly recognisable as LINK which i have used in the past so it saved me the hassle of learning new hotkeys, map navigation and so forth.
The Vi-PEC is a highly capable unit and is a breeze to tune but, is it any differrent to the run-of-the mill G4 plug in LINK? i think not but if both are priced the same i can see no issue either way, the benefit being it is twice as easy to source and is now well backed locally.
The car i fitted it to was a SERII R33 with FMIC, full exhuast and a profec b spec II
Peak power was 210rkw after final tune and peak torque was 346nm @ 11psi without the dip in the graph which was boost controller setup. I attached the last run i saved for refference.
