Well I've tested and adjusted it with a IAW monitor ... but I will try to find a new PF09, just to try another, but I've not had any luck yet :-(
Any chance that you know a place to get a new one ??
If you have set it up with the iaw then it should be fine and if you see a steady rise then again it should be ok.
As for a new one there getting thin on the ground could try ducati bike dealers or moto guzzi as some of there models use the pf 09. also as you know fiats,lancias use them too.
What plugs you using? also what leads? hear that some blue motorsport leads are not so good.
Make sure your leads are not near the map sensor as this also can cause issues.
Are your earth cables ok? its been suggested on here by a tuner to put an extra earth on the ecu to body.
Hope you sort your issues out as wasted spark when working correctly can't be beaten.
