With pretty much everything where I want it to be with my vx220 I am quite happy with it, except the ECU, which has never been quite right.
So I hatched a plan and have been gathering parts ever since.
"What do I need from a new ECU" - well I have always wanted to use individual coils (Saab B207), seqential injection (better emissions for MOT), use the original z22se Injector position and fuel rail (I was going to use the original vx220 fuel lines, but I hate the way they lap around the engine bay), plus the 60-2 trigger wheel
So far;
Located a LSJ cam sensor and modified it to fit my engine -

Picked up a brand new set of Bosch 470cc injectors (astra vxr) for £140 from Germany, I will be using the OEM Saab injector spacers
Ordered a Penny and Giles 'red' Throttle Poisition Sensor
Modified a single feed fuel rail for fuel return
I machined a piece of alloy to match the dimensions of the original end and then added the fuel return fitting
