No dont think it can be done bud. The C has over 20 different modules throughout the car, in affect an ECU for each different part of the car. Each door has its own "ECU", you cant just wire in things, you also have to program the ECU to do thing, even adding electric windows. With that in mind, each Module is coded to to the car and on many cases to each other. If you've seen the term Canbus an the astra h forums then this applies to the Vec C as well.
So to cut a long story short the Vec C used its own ECU to tie in with the Can Bus system, and from what i'm aware its a dead dodo, all the big Vauxhall tuners wont offer a map for it only the none Canbus Z22se's. 🙁
By the way, if it is a 52 plate C (that was the first year of the C) then benny said he came across many a 52 plate C with the old small oil jet still fitted even though VX said they never carried it over to the C.
