        This was the reason I didn't go with this conversion about
6 months ago. That ECU is listed as for the international market
(according to someone who was very helpful on the list). I never
did try to match pins to see if it was anything like the 2L digifant II
units. I tried writing Bosch via both email and snail mail and never
got a response. Hopefully you two will have better luck.
        I tried to work out a deal with TIIco to modify the wiring
harness pins to work with the Digifant II Ecu (so this thing could
be sold in ca as smog legal as it would just be a swap with a reman'ed
motor). They were not interested in working out a deal were they
got me a digifant II ecu in exchange for the SA one.... oh well.
That and the price kept going up every time I talked to them.

        One more thing - do these engines you guys have received have
2.0L stamps on them or 1.8 (it's on the back of the block below the
exhaust manifold)?
