I recently discovered that the fuel injectors on my 7 port were a massive 480cc, and usually fitted to a Vauxhaull Zafira VXR. So based on some advice and a few formula's I changed them down to 220cc.
When changing from one injector size to the next, how linear is the relationship between injector and a fueling compared to the next? For instance in this case I'm moving to an injector which is near half the size of the prior injector. So could I literally double all my pulse rate values in the theory 480/220 is x 2.18....and hence multiply all values by 2.18 throughout the whole map. Then tweak individual points as necessary using my AFR gauge readings?
Any help or suggestions would be much appreciated thanks!
