Ive been looking into it and looks like the best option is going to be megasquirt and some gsxr throttle bodies this will also eliminate the issue of the original throttle body hitting the bonnet. Ive no experience with megasquirt but as clarkson would say " how hard can it be ? ".
Im a bit dissapointed with myself as the last car i built the donor ecu and custom loom i made worked brilliantly ! No immobiliser to mess with on that though.
Suppose i best let this thread go now ! Sorry for the hijack
