Alfa Wiring Diagram Needed - Urgently

Be careful Guy or you could go too far the other way with just as drastic results. 3.1kg/cm2 this is a smidge over 3 bar which is 43.5 PSI. loads of converters on the web. This would be without the vacuum pipe connected I would expect. When connected it will then vary this when the engine is running and under load or sudden throttle opening. Rolling road and a way of measuring your exhaust gasses with an analyser or wideband lambda is the only sure way of getting this mixture right. Generally a standard ECU will cope with minor performance changes, however there is a lot of discussions about 12v injectors being near their limits hence people upping fuel pressure to richen mixtures or swapping injectors but often ending in tears, only a rolling road session will confirm what the engine needs. Until you confirm this I'd not do any high speed runs a running lean will have just as dire consequences

Thanks Rob, I'll have another look at it when it's cooled down somewhat and see what the pressure is with the vacuum tube disconnected and adjust it up a tad.

Guy

Great news to hear you've got it running Guy and thanks for sorting Donna today. Chuffed to bits with the lights. I'll see you at Stoneleigh for beer or three and with a bit of luck and hard graft, I'll be in the yellow peril. :)
