Which ECU?
I've got a part-built kit with a red top but without an ecu. How do I know which one I need? It's got a dispac on it but I don't
know which Vauxhall the engine came out of.
Thanks

Are you running original injection or carbs/throttle bodies?
If the first you could get a ECU M2.8 from a later Astra gsi
if second, most aftermarket ecus might be ok... Megasqurt/jolt. once again depends if carbs or tbs?

go with whatever stock was to begin with. Once you start using aftermarket ECU's, you have more in that than your engine. I know I do.

Yes if you have stock engine with original injection then that's the ecu. The earlier ecu worked with distributor.

All of the distributor-less C20XEs would have been fitted with a cat and oxygen sensor wouldn't they? Can you run them with this disconnected
without it throwing error codes and possibly limp home mode?

If he;s IVA'ing it, he'll probably need cat and lambda anyway

I've got a cat already - in the custom made exhaust. Where in the system should the lambda sensor go?

Just after the last collector, before the CAT
