np, I didn't realise there were that many people having issues with them...I basically learnt the hard way having a crash course learing how the thing worked when my car had the turbo conversion. It's a shame I still don't have it as I could have brought it down for all to see. I've never used the E-01 just the laptop interface, even with that the car just fired up first time and all adjustments through the software worked fine, ignition advancing/retarding and fuel adjustment, scaling to the boost map and the fuel cut defender was a matter of setting the max AFM voltage to just bellow the cut-out and fixing it there.
Power FC is a full replacement so sort of in a different category to a piggyback
Let me know the exact details of what issues you have and maybe I can help you guys out. The two I've seen with issues have been the wrong firmware update and a 100% faulty unit.
