Heres a forum i found guys where an aussie guy did the conversion, not sure if anyone else has stumbled on this. Not sure why he didnt go with Mivec ecu, would of saved him the hassles with the intake lenth control, and the first version from the 95 30M Diamante is slightly different to the 96/97 ones and easily tuned . This is according to kiwi mivec site, something to do with the ecu type. anyway heres the link..........http://www.mogwa.org/forum/phpBB2/viewtopic.php?t=7344&postdays=0&postorder=asc&start=15&sid=d99d4e73b0e487ed31e556f1bb2e1f3c

interesting man still a lot of money for a conversion
wouldnt it be cheaper just to buy one and send to oz from nz
like this one for 2600 nz so 2100approx au

And this comment is a bit of a worry,

''lost HP across the range, including peak. At the MIVEC cut-in, the graph went nearly vertical, but did not catch up to the first dyno run.''
